The new CLA is designed throughout for the electric and digital age at Mercedes-Benz. As the first model of an entirely new vehicle family, it embodies the next evolutionary step in the Mercedes-Benz design philosophy of Sensual Purity. The Concept CLA Class already previewed this dynamic appearance combined with extraordinary design elements: The production model is equally striking with an exciting interplay of intelligence and emotion, redefining desire.
With its fastback silhouette, the CLA stands for outstanding aerodynamics and efficiency. The long wheelbase (2,790 millimetres), short overhangs and a distinctive GT rear are an emotional expression of athletic power. The car's sporty proportions are enhanced thanks to a low greenhouse, long bonnet with power domes and large wheels up to 19 inches. The car's muscular and athletic shoulders start at the front wheel arches and extend to the sculptural rear. The flared wheel arches and wide track (front/rear: 1,605/1,574 millimetres) reinforce the dynamic impression.
The clear design language emphasises the sculpted surfaces with reduced lines and precise joints. The striking character lines on the flank create an interesting interplay of light and shade when viewed side-on. The powerful design conveys sporty confidence and modernity, giving the CLA a visual lightness. The meticulous attention to detail underscores the high quality and exclusivity of the new model.
More space at every seat and for luggage - the frunk returns after 90 years
At 4,723 millimetres, the new CLA is about four centimetres longer than its predecessor. The wheelbase has increased by over six centimetres to 2,790 millimetres. The driver and front passenger have slightly more legroom (plus 11 millimetres). Passengers in both seat rows also have more headroom: an increase of 16 and 28 millimetres (front/rear). This is due to the higher roofline and the standard-fit panoramic roof, which lets in plenty of light and creates a sense of freedom.
The CLA with EQ Technology is the first modern Mercedes-Benz with a frunk (front trunk). It offers 101 litres of additional load space - ideal for a luggage trolley, a crate of 0.33-litre bottles or the charging cable. This makes it bigger and more useful than in the Mercedes-Benz 130 (W 23) from the 1930s, which was the brand's first vehicle with a frunk. At the rear, the new electric CLA offers a luggage compartment with a volume of 405 litres.
Brightens the day and night: panel with illuminated Mercedes-Benz pattern and headlights in star design
The sporty front end of the all-electric CLA features a shark-nose design. The highlight is the new panel with illuminated Mercedes-Benz pattern, which reinterprets the classic chrome grille. Seamlessly integrated into its surroundings, this design element not only includes the large iconic Mercedes-Benz star but also features a total of 142 chrome-effect stars, creating a distinctive brand signature. The illuminated grille greets and bids farewell to the driver with various animations. Depending on country-specific regulations, the central star may also be fully or partially illuminated.
Full-LED headlights provide an emotional and striking appearance both day and night, as well as optimum illumination of the road. They are connected by a band of light. The innovative star design contributes to the unmistakable brand identity. With the optional MULTIBEAM LED headlights, the daytime running lights are designed in the shape of the Mercedes-Benz star. The standard LED High Performance headlights feature the star as a chrome-plated design element.
The frameless doors with chrome trim emphasise the sportiness and timeless elegance of the new model. The large panoramic roof comes as standard and brings plenty of light into the interior. The compact exterior mirrors are mounted on the beltline. The retractable door handles (optional in conjunction with KEYLESS-GO) are flush with the body and contribute to optimised aerodynamics.
The GT rear end gives the CLA a powerful presence. The star-shaped taillights are connected by a band of light, which is animated with coming-home and leaving-home scenarios. As is typical for sporty Mercedes-Benz vehicles, the license plate is positioned in the bumper. The rear diffuser is elegantly painted in high-gloss black, aerodynamically optimised and contributes to the model's excellent drag coefficient. Alloy wheels come in a choice of ten exclusive designs, ranging in size from 17 to 19 inches. All wheels have also been aerodynamically refined.
Best-in-class standard equipment
With the all-new CLA, Mercedes-Benz offers even more upgraded standard equipment. Every CLA is delivered in the Progressive Line as standard. The equipment includes LED High Performance headlights, the Mirror Package, a multifunction leather steering wheel in a sport design, comfort seats in ARTICO man-made leather/fabric with seat heating and 4-way lumbar support, and the THERMATIC single-zone climate control with air vents for the second row. Four USB-C charging ports with a power output of 100 watts further enhance passenger comfort.
The highly successful AMG Line is available as an option, further emphasising the vehicle's sportiness. Exterior features include 18-inch alloy wheels, a front bumper with air intakes and a chrome splitter and a specific rear bumper. When the door is opened, drivers are greeted with an animated light carpet featuring a star pattern. The interior of AMG Line vehicles features sporty accents such as a sports leather steering wheel with a flattened rim and red contrasting stitching on the door panels. It also has sports seats in black ARTICO/MICROCUT and an AMG sports pedal set in brushed stainless steel with black rubber studs.
For a more exclusive appearance, the Night Package is available as an option. It can be combined with both the standard equipment and the AMG Line. It includes high-gloss black trim elements on the bumpers, E-line and beltline, a high-gloss black upper casing on the exterior mirrors and tinted rear windows. The package also includes specific 18-inch alloy wheels.
For customers who prefer even more sportiness, the AMG Line Plus is available for the first time. It adds additional design elements from the AMG Performance Programme to the AMG Line. These include a high-gloss black rear spoiler, illuminated high-gloss black door sills and exclusive 19-inch alloy wheels. Red MANUFAKTUR seat belts and the Night Package complete the AMG Line Plus.
Light-flooded ambiance: panoramic roof with heat protection coating fitted as standard
All CLA models come as standard with a large panoramic roof. This one-piece fixed glass roof has no central brace and extends seamlessly from the windscreen frame to the rear. This design provides a new interior experience with an almost unobstructed view upwards. It also contributes to more generous headroom in both seating rows compared to its predecessor.
Heat-insulating laminated safety glass protects against sunlight. The exterior surface is coated with a 250-nanometre thin infrared film that reflects long-wave radiation, reducing potential glare. For comparison, a human hair has a diameter of about 50,000 nanometres. The equally thin 200-nanometre Low-Emissivity (LowE) coating on the interior side of the panoramic roof reduces the emissivity of the glass and serves as heat protection. This design eliminates the need for a roller blind, creating an even airier impression.
New spatial experience: visual reduction to a few floating high-tech elements
The interior of the CLA offers a new luxury experience in this vehicle class. The previous sculptural automotive design has been replaced by a new design concept that follows the principle of reduction to the essentials. It de-emphasises the underlying structure and focuses on a few iconic high-tech elements. This radical reduction characterises the avant-garde style of the interior. The inspiration for the control elements came from modern product design in the consumer electronics sector.
The highlight of the interior is the optional, floating MBUX Superscreen, which extends across the entire interior width. Behind a large glass surface are the 26-centimetre (10.25-inch) driver display and the 35.6-centimetre (14-inch) central display (for display and control concepts, see separate chapter), both with LCD technology. After market launch of the CLA, the MBUX Superscreen will be available as an optional extra with an additional 35.6-centimetre (14-inch display) for the front passenger. If no passenger display is installed, a trim element with a star pattern graphic continues the glass look in this area. Depending on the equipment, a backlit version is also available.
Round air vents are integrated at either end of the MBUX Superscreen, enhancing the modern and sporty impression. Their rings appear to float in front of the funnel-shaped moulding. A flat central vent with a high-tech appearance replaces the usual louvres. Another extra is the head-up display. Approximately 2.8 metres in front of the vehicle, the driver sees a floating, virtual 31-centimetre (12.2-inch) image.
The doors offer a wow effect with their large centre panels, which likewise appear to float. This element makes the concave underlying structure recede into the background. Open storage compartments are integrated into the door panels. The pull handle in classic tubular design appears reduced, powerful and sporty. The switch for electric seat adjustment is also completely redesigned. Its body has a circular form and a high-quality galvanised surface finish.
The third highlight in the interior is the centre console. Appearing to float in mid-air, its high position enhances the sporty feel. From the armrest between the front seats, it reaches forward beneath the Superscreen. As in higher vehicle classes, it is split into two levels: The upper section offers an expansive, three-dimensional trim surface, available in a wide range of decorative finishes. Integrated into this trim element are a double cup holder and an optional wireless smartphone charging cradle.
New multifunction steering wheel with simplified controls
The CLA comes as standard with a new multifunction steering wheel. The switch panels on the left and right are capacitive and seamlessly integrated into the surface. The operation of the steering wheel has been changed compared to the previous generation: tactile aids around the symbols make orientation easier. In general, many functions have been removed from the control panel for better usability. Only a finger navigation pad for controlling the content on the driver display is now present on the right side. This enabled significant enlargement of the individual functional areas. Additionally, the mute function has been removed from the volume slider. It is now available as a separate symbol at the top of the right switch panel. The volume can be finely adjusted by sliding or pressing the - and + points, the latter with haptic feedback. For the first time in this vehicle segment, the steering wheels is also available in ivory beige.
Seats made from recycled materials in a luxurious layer design
Two types of seats are available in the new CLA: The standard-fit comfort seat is generously sized and invitingly designed. In the shoulder area, it features the so-called layer design familiar from higher vehicle classes. The sports seat also follows this design, where the layer design connects the seat surface and side bolsters into a single unit. The layer tapers upwards into the backrest and adopts the slim design of the headrest, which has an integrated look. It, too, appears to float and is height adjustable.
Both seats incorporate secondary materials throughout their construction - from the seat cover and seat foam to the substructure and metal components. Mercedes-Benz offers five upholstery options for the comfort seat, including black man-made leather, with backing fabric made from recycled PET bottles. These bottles are regranulated, spun into yarn and finally processed into textile. Sustainably produced and processed leather is also available. Every step of its production is considered - from cattle farming to the tanning process. The leather is chrome-free, tanned with mineral, synthetic or vegetable tanning agents such as coffee bean husks, chestnuts or extracts from other renewable raw materials.
The microfibre fleece MICROCUT is made from 100-percent recycled material. First, PET bottles are processed into regranulated yarns. Using a sophisticated microfibre process, these are used to create a high-quality and durable fleece that has the look and feel of suede. This material is used in selected AMG Line upholstery, on the seats as well as the centre panels and door armrests.
The floor covering is also made from secondary material. The Econyl yarn is produced from 100-percent recycled material.
Modern luxury reinterpreted: exclusive colours and trim elements with innovative surfaces
A balanced variety of colours and materials underscores the luxurious overall experience in the interior. The attractive and extensive range of exterior paints, as well as interior colours and materials, allows configuration of the CLA according to personal taste. Here are four examples:
Two exclusive paint colours developed for the CLA: aqua mint uni and clear blue metallic
Special interior accents: Leather in beech brown, available in the standard Progressive Line as well as the AMG Line.
To emphasise the sporty character of the CLA: The AMG Line offers microfibre and ARTICO upholstery with a technical-looking pearl effect in black/clean white pearl. The Colour & Trim specialists have reversed the usual colour distribution on the seat, with the stronger colour now adorning the shoulder area. A textile strip in the centre of the seat and piping on the outer sides showcase the highest craftsmanship.
The AMG Line also offers sporty-looking leather upholstery in black with green accents.
The selection of large, high-quality trim elements is equally varied, inspired by offerings from higher vehicle segments. In addition to surfaces made of open-pore wood, brushed aluminium and anodised-look coatings, a trim element made from paper, which is unique in the auto industry, is also available. It is made of cellulose and hemp fibres and is very robust. This high-quality decorative surface offers a completely new look.
Personalised ambient lighting: diverse settings for a cosy atmosphere
In typical Mercedes-Benz fashion, the ambient lighting enhances many areas, from the instrument panel to the rear doors. Indirect light sources emphasise the floating character of the three central components: Superscreen, centre console and door centre panel. This creates a special feel-good atmosphere in the interior. The many settings - 64 colours plus ten colour worlds, 20 brightness levels and three brightness zones - allow for optimal customisation.
Individual sound experience: optional Dolby Atmos and standard holistic "SoundExperience"
A Burmester® 3D Surround Sound System is available as an option. With Dolby Atmos, it enables an unparalleled multidimensional music experience. This sound system includes 16 speakers and an 850-watt amplifier. For the first time, silver chrome covers for the tweeters and midrange speakers further enhance the interior's visual appeal.
The all-new Mercedes-Benz CLA: the Mercedes-Benz Operating System and driving assistance systems
The new CLA is the first vehicle to operate entirely on the in-house developed Mercedes-Benz Operating System (MB.OS). This makes it the cleverest Mercedes-Benz ever made. The deep integration of the chip-to-cloud architecture into the vehicle provides control of all actuators and sensors for an unparalleled immersive experience and intelligent integration of vehicle functions into the user interface. MB.OS is the brain of the new CLA. It controls four areas: infotainment, automated driving, body & comfort and driving & charging. At its core, MB.OS helps decouple hardware and software, making software development faster and more adaptable.
Starting with the new CLA, Mercedes-Benz divides the technological intelligence of its vehicles into three categories: MBUX, MB.DRIVE and MB.CHARGE. MB.DRIVE is the new umbrella term for intelligent driving assistance systems.
Thanks to MB.OS, the CLA is up-to-date for years and always ready for new functions
The CLA is equipped with supercomputers connected to the Mercedes-Benz Intelligent Cloud. This enables over-the-air updates of the entire vehicle software, including driving assistance systems for the first time. This keeps the CLA up-to-date and attractive for years, similar to a smartphone that regularly receives new apps and extended functions. To provide customers with top-notch content and experiences, Mercedes-Benz collaborates with leading global partners like Google and Microsoft. The Mercedes-Benz Operating System offers maximum flexibility to seamlessly integrate content from third-party providers. The typical Mercedes-Benz user interface remains intact, ensuring the familiar and valued customer experience.
The Mercedes-Benz Operating System also features more efficient software performance. As a result, over-the-air updates consume significantly less energy compared to the previous system. With MB.OS, Mercedes-Benz sets new standards in energy efficiency through advanced technologies, the implementation of power-saving modes and intelligent function control. This means more range and fewer carbon emissions.
Launch of the fourth MBUX generation: exceptionally intuitive and personalised
The proven and popular infotainment system Mercedes-Benz User Experience (MBUX) now runs on MB.OS, marking the start of the fourth MBUX generation. It opens up a new world of personalised experiences and intuitive interaction between humans and vehicles, setting new standards in the automotive industry. The new MBUX generation is the world's first in-car infotainment system to integrate artificial intelligence (AI) from both Microsoft and Google, combining multiple AI agents in one system for the first time.
The up to three screens are powered by state-of-the-art high-performance chips and real-time graphics from the Unity Game Engine. The new operating and display concept is tailored not only to the vehicle but also to individual customer preferences, following the design principle of reduction to the essentials. The enhanced MBUX Zero Layer on the central display shows the most important information, suggestions and, for the first time, recently used apps. In the app grid, apps can now be moved and grouped into individually named folders, similar to a smartphone. When an app is open, a simple swipe to the left returns to the app grid. Another swipe takes the user back to the Zero Layer. Alternatively, they can still go directly to the Zero Layer at any time via the home button.
The MBUX Virtual Assistant: intelligent, easy to talk to and empathetic, like a friend
With generative artificial intelligence (AI), the new MBUX Virtual Assistant revolutionises the relationship between vehicle and driver. It is the next evolutionary step of the MBUX voice assistant and goes far beyond responding to commands. The MBUX Virtual Assistant enables complex, multi-turn dialogues - like you have with a friend - and has short-term memory. It is activated by saying "Hey Mercedes." Based on ChatGPT4o and Microsoft Bing search, it unites the collective knowledge of the internet. For example: "Hey Mercedes, when does the cherry blossom season start in Japan?" - "And when does it start in Germany?" Users can speak naturally without thinking about specific formulations. For instance, the virtual assistant can answer questions like "Hey Mercedes, what is a black hole? Explain it so that children can understand."
Thanks to Google Gemini, the MBUX Virtual Assistant is also well-versed in navigation-related questions. The Automotive AI Agent from Google Cloud, developed with Gemini via Vertex AI, is specifically tailored to the automotive industry. It can access information from the Google Maps platform to provide users with detailed and personalised answers to questions about navigation, points of interest and more. For example, it can respond with suggestions to the question: "Hey Mercedes, I have a date today. Do you have any ideas for something special to do around here?"
The MBUX Virtual Assistant can retain context. It can switch between the Automotive AI Agent from Google and ChatGPT, depending on the topic being discussed. This means users can continue conversations and retrieve information throughout their journey. The virtual assistant is always present on the Zero Layer as a "living" avatar in the form of the Mercedes-Benz star.
During an active dialogue, it recognises emotions and can respond accordingly. The star avatar provides visual feedback through colour-coded animations to express moods and show empathy. In the default setting, it is blue (red with the AMG Line). If it detects that the customer is in a positive mood, it turns green. If the MBUX Virtual Assistant notices pronounced happiness or excitement, for example, about a planned date, the avatar becomes more vivid and colourful. In the case of anger or sadness, it changes to orange/red. With different animations, the Virtual Assistant also signals whether it is speaking, listening or processing. Movement, brightness, intensity and colour interact seamlessly to communicate intuitively with the driver.
Individual entertainment for the front passenger
On request, the new CLA offers the front passenger their own 14-inch screen for individual entertainment. The continuously growing app portfolio includes video streaming platforms such as Disney+. Disney+ is a popular streaming service that offers a wide range of films and series from Disney, Pixar, Marvel, Star Wars, 20th Century Studios, FX, Searchlight Pictures and National Geographic. Offering an unmatched collection of exclusive originals and an ever-growing library, Disney+ is available in the new CLA and will soon be available in other Mercedes-Benz models. Also available are the video-streaming platform RIDEVU from Sony Pictures Entertainment and video games with a wide selection of triple-A titles via the cloud-gaming provider Boosteroid. To enjoy the best in-car gaming experience, customers can use their Bluetooth gaming controller or mobile phone. The gaming controller can be used with the passenger display even while driving. The central display can only be used for this when parked.
The passenger display screensaver can also be customised with personal images. Numerous safety precautions, such as eye-tracking technology, ensure that the driver is not distracted.
MBUX Surround Navigation: seamless integration of assistance and route guidance
Integrated visual communication also reaches a new dimension with MBUX Surround Navigation. Thanks to the deeply integrated architecture of MB.OS, the advanced navigation system shows a real-time view of the vehicle and its surroundings. The system seamlessly combines the driving assistance view with a 3D representation of the surroundings and route guidance on the driver display. It shows other road users such as cars, bicycles, motorcycles and pedestrians. The integration of information into the driver display using 3D game engine graphics provides an extremely intuitive overview.
Drivers benefit from improved situational awareness as they see what the CLA sees and how the assistance systems are supporting them. This also builds trust on the path to autonomous driving. The display of route guidance in an environmental representation is particularly helpful in busy urban traffic. Customers can see early on what lies ahead, such as behind the next turn. Buildings and other infrastructure are easily and quickly recognisable. The system also provides an integrated overview of vehicle status through real-time virtual-reality visualisation, including the illumination of indicators, high and low beams. Acceleration and deceleration are visualised by the adjusted speed of the wheels.
Intelligent navigation you can trust, with tailormade route guidance from Google Maps
In the new CLA, the navigation experience is based on Google Maps. The unique navigation system offers Mercedes-Benz customers the best of both worlds: core services from Google Maps as a recognised benchmark and the trusted user interface from Mercedes-Benz. This offers the familiar Mercedes-Benz services for charging and parking. The navigation solution in the CLA, developed in partnership by Google and Mercedes-Benz, is one of the first systems to integrate Google Cloud's new Automotive AI Agent for in-vehicle use with Google Maps.
Mercedes-Benz Navigation with Electric Intelligence plans the fastest and most convenient route, including charging stops, based on numerous factors. It dynamically responds to traffic jams or changes in driving style. Mercedes-Benz is continuously developing the energy forecast for Navigation with Electric Intelligence. In the future, predicted wind conditions along the road will be considered even more accurately based on the vehicle's height.
To work out the route, the system calculates energy demand. It takes into consideration topography, route profile, ambient temperature, speed, heating and cooling needs. Other factors include the traffic situation on the planned route and the available charging stations, their charging capacity and payment functions. The calculation takes place in the cloud and is combined with onboard data.
The intelligent navigation recognises when a charging stop is necessary and plans it automatically to optimise overall travel time. Sometimes, two short charging stops with higher charging capacity may be more beneficial than one longer stop. Additionally, the vehicle's charging settings are automatically adjusted by Navigation with Electric Intelligence and optimised for fast charging along the route. This includes preconditioning the high-voltage battery to ensure it is at the optimum temperature for high-speed DC charging at the right time. The system also provides energy-saving tips.
Mercedes-Benz is the first automaker to introduce an integrated reservation function for charging stations. Starting in Germany and the USA, Mercedes-Benz customers can exclusively use the integrated charging service MB.CHARGE Public to reserve a charging point in advance at the company's own Mercedes-Benz charging parks. When route guidance using Navigation with Electric Intelligence is active, the vehicle automatically makes the reservation 15 minutes before reaching the charging station. For drivers, the reservation function saves time spent waiting and provides them the assurance of an available charging spot.
KEYLESS-GO now with automatic locking and unlocking
The new CLA is available with the optional KEYLESS-GO feature. In the latest generation of this access system, and depending on market availability, the vehicle automatically locks or unlocks when the user with the vehicle key approaches or moves away. This feature can also be deactivated via the head unit if desired. Additionally, KEYLESS-GO is optionally available with Handsfree Access, allowing automatic opening and closing of the boot via a kicking motion under the rear bumper.
MB.DRIVE sets a new standard with advanced driving and parking assistance systems
The all-new CLA models in Europe come standard with extensive safety equipment and the Distance Assist DISTRONIC. Technical details include eight cameras, five radar sensors, twelve ultrasonic sensors and a water-cooled supercomputer with sufficient power reserves for future functions and regular over-the-air updates.
The all-new Mercedes-Benz CLA: drivetrain, chassis, aerodynamics and safety
The all-new CLA with EQ Technology is the "one-litre car" for the electric age. With remarkably low consumption and impressive range in this segment, it elevates the real-life practicality of electric mobility to a new level. Initially, the CLA 250+ with EQ Technology and the CLA 350 4MATIC with EQ Technology will be launched. By the end of the year, the model range will be expanded to include additional battery-electric variants and the CLA with a high-tech hybrid engine (see separate chapter).
With a range of up to 792 kilometres according to WLTP, the CLA 250+ with EQ Technology offers a large radius in its class. This 200 kW model variant can travel from Stuttgart to Kiel or from Bremen to Munich without charging stops. The 260 kW CLA 350 4MATIC with EQ Technology is positioned as the performance version at the top end of the model range. It combines high efficiency with immense driving pleasure and outstanding performance, accelerating from 0 to 100 km/h in just 4.9 seconds. Both power levels reach speeds of up to 210 km/h.
800-volt technology makes charging almost as fast as refuelling
Highlights of the all-electric CLA include the 800-volt electrical architecture and advanced drive units with a two-speed transmission on the main drive at the rear axle. The 800-volt system maximises efficiency and performance and can significantly reduce charging time in conjunction with the new battery generation. The CLA with EQ Technology can recharge with up to 325 kilometres of range in just ten minutes. Fast DC charging is possible with up to 320 kW for both the CLA 250+ and CLA 350 4MATIC.
Newly developed electric drive system with 93 percent efficiency
With the main drive on the rear axle for optimal traction and driving characteristics, Mercedes-Benz brings a drive layout known from the mid and upper classes to the entry-level segment. The 200-kW electric drive unit with a permanently excited synchronous motor (PSM) on the rear axle was developed entirely in-house and is directly derived from the VISION EQXX unit. Battery-to-wheel efficiency over long distances is 93 percent.
The magnets in the rotor are arranged in a double-V shape. Another feature is the winding of the stator with so-called hairpin windings. These measures contribute to an especially quiet drive. The PSM also has a significantly lower proportion - almost zero percent - of heavy rare earth elements compared to previous motor generations. The high-performance power electronics are equipped with a silicon carbide (SiC) inverter for particularly efficient energy use. Transmission control and inverter are highly integrated into a single component.
Sprinter and marathon runner in one: two-speed transmission combines dynamics with high efficiency
The drive architecture includes a two-speed transmission on the rear axle, combining performance with efficiency. The first gear has a short ratio of 11:1, enabling excellent acceleration right from the start, a high towing capacity and great efficiency in urban traffic. The second gear (ratio: 5:1) is designed for power delivery at high speeds and high efficiency on the motorway for outstanding long-distance range and comfort. The top speed is also achieved in the second gear.
The shift points depend on the driving situation and the selected driving programme. Additionally, the online optimiser continuously adjusts them to current parameters such as battery charge level, power and driver requirements. Power is transmitted via claws (1st gear) or discs (2nd gear). The transmission has special thermal insulation.
The Electric Drive Unit (EDU) 2.0 resolves the conflict between maximum torque, top speed and excellent efficiency - especially in real-world driving. The high torque not only ensures dynamic driving performance but is also helpful for tackling inclines on mountain passes or towing loads. The all-electric CLA models can tow up to 1.8 tonnes with the semi-electric trailer hitch (optional), making them suitable for towing compact caravans.
Additional power only when needed: 4MATIC models with Disconnect Unit
The CLA 350 4MATIC all-wheel drive model also features an 80 kW drive unit on the front axle. This unit is likewise equipped with a silicon carbide (SiC) inverter for efficiency and is designed as a permanently excited synchronous motor (PSM). The front electric motor functions as a "boost" drive, activated only when additional power or traction is needed, depending on the driving situation or programme. This task is handled by the Disconnect Unit (DCU), which Mercedes-Benz is using for the first time in this segment.
For higher efficiency, the DCU can quickly decouple the front electric motor under low load, causing the electric motor and parts of the transmission to stand still. This reduces front axle losses by up to 90 percent and increases range.
"Free" heat for efficient pre-conditioning: multi-source heat pump as standard
The all-electric CLA is the first Mercedes-Benz to come as standard with an air-side heat pump. It no longer takes a detour through a water circuit and can use three energy sources in parallel as a so-called multi-source model: waste heat from the electric drive, the battery and ambient air. The air-to-air heat pump contributes to the high efficiency of the CLA by utilising this "free" heat. It uses about one-third of the electrical energy that a comparable auxiliary heater would need for the same output.
In addition to high thermal comfort for the occupants, the multi-source heat pump also enables the CLA's very high charging performance. It brings the high-voltage battery to the ideal temperature range before fast charging. The battery is integrated into the intelligent thermal management system. When Navigation with Electric Intelligence is activated, the battery is preheated during the drive if necessary, reaching the optimal temperature for fast DC charging at the charging point. Mercedes-Benz ensures that efficiency does not come at the expense of cabin warmth, keeping the interior at a comfortable temperature during fast charging.
Intelligent recuperation for maximum range
The all-electric CLA features a new one-box brake system. Previously separate components such as the brake booster with master brake cylinder and ESP control are combined into a compact module - hence the name. The system optimises the recovery of braking energy, increasing range. The by-wire concept ensures a consistent, assured and transparent brake pedal feel for the driver, regardless of whether braking is through recuperation or friction braking. Additionally, the new brake system meets the brand's high safety standards. In the event of a fault, the system reliably switches to the hydraulic fallback, ensuring safe braking behaviour at all times.
For efficiency reasons, almost all braking processes are carried out entirely through recuperation. The recuperation power is up to 200 kW. In principle, the models can even brake electrically to a standstill, thus recovering kinetic energy. The strong deceleration (up to 3 m/s² per axle) means more recovered energy and, ultimately, a longer range. Recuperation is possible even during ABS braking or on icy roads.
The selector paddle behind the steering wheel serves for more than just selecting driving modes. The driver can also use it to adjust recuperation power. Pulling the lever towards the steering wheel increases the level of recuperation to a deceleration of up to 3 m/s². Pushing the lever towards the driver display reduces energy recovery accordingly. Further pressing the selector paddle switches between the recuperation levels D+ and D Auto.
Top battery with silicon-oxide anodes and high energy density
The innovative battery system is based on a highly integrated modular architecture. The batteries consist of four large cell modules with hardcase cells and feature a compact and flat design. The CLA 250+ and CLA 350 4MATIC use the top variant of lithium-ion batteries with a usable energy content of 85 kWh. The cells' anodes are made from graphite mixed with silicon oxide. Compared to the previous battery with conventional graphite anodes, the gravimetric energy density has been increased by up to 20 percent. The volumetric energy density of the cell chemistry is 680 Wh/l. The cobalt content has been further reduced. At the end of the year, a CLA model with a battery featuring lithium-iron-phosphate cathodes (LFP) will follow. The usable energy content is 58 kWh, while the volumetric energy density of the cell chemistry is 450 Wh/l.
Despite significantly increased charging power, the terms of the battery certificate for the EQA and EQB still apply to the all-electric CLA. For a total duration of eight years or up to a total distance of 160,000 km (whichever comes first), Mercedes-Benz guarantees that the maximum battery capacity of the high-voltage battery will not be less than 70 percent.
The CLA provides power storage for the home: prepared for bidirectional charging
The all-electric CLA is prepared for the networking of electric vehicles with the power grid. When the vehicle is connected to a compatible bidirectional DC charging station, it becomes an energy storage unit that can store, for instance, solar power for later use. More importantly, it can also serve as a power supplier, either Vehicle-to-Home (V2H) or Vehicle-to-Grid (V2G).
The bidirectional charging function will be available at a later date, after market launch, through an over-the-air update. The use of bidirectional charging may be subject to market-specific conditions regarding legislation and the requirements of energy providers.
Class-leading aerodynamics with a drag coefficient starting at 0.21
Low air resistance means high efficiency, making aerodynamic performance particularly important for electric vehicles. Reducing the drag coefficient by just 0.01 increases the long-distance range by about 2.5 percent. With a drag coefficient starting at 0.21, the all-electric CLA leads its segment.
The variation within the model range is minimal, partly due to the wide range of aerodynamically optimised wheels. This includes, for the first time, a two-tone full cover for alloy wheels, which improves the drag coefficient by up to two points compared to a conventional rim. Additionally, the aerodynamics team has optimised the wheel spoilers forward of the front and rear axles across all wheel sizes, minimising the impact of wheels and tyres on air resistance.
Around the grille and headlights, the joints are optimally positioned and partially sealed. The underbody concept from the EQS and EQE has been further developed. The very smooth underbody is almost completely closed, with even the control arms and tie rods covered. The rear wheel cover is fixed to the body, meaning there are no joints with surrounding components. It therefore does not move with the axle during, for example, compression. The CLA has a so-called impact management system to protect the battery, with fully integrated components that have also been aerodynamically optimised. To avoid aerodynamic compromises, there are two diffuser variants for the rear of the all-electric CLA: for models with and without a trailer hitch.
Comfort suspension with multi-link rear axle from the mid and upper class
The CLA comes as standard with a steel-sprung comfort suspension featuring a newly developed three-link front axle. The lower control arm comprises the transverse and thrust arms, both made of forged aluminium. As with a McPherson configuration, the strut guides the wheel and is directly connected to the steering knuckle. The third link, the tie rod, is part of the rack-and-pinion steering. The transverse steering gear is positioned in front of the wheel centre, leading to the desired self-steering behaviour and precise steering response. The steering knuckle, connecting the lower control arm with the strut and supporting the wheel and brake system, is made of cast aluminium. In addition to lightweight construction, high camber stiffness was prioritised for this component, creating the best conditions for good steering response and low noise.
At the rear is a newly developed multi-link axle. This high-quality suspension concept is well known from Mercedes-Benz vehicles from the mid- and full-size classes. The company is now also bringing it to this segment.
High level of active and passive safety - first centre airbag in this vehicle class
The all-new CLA is developed from the ground up with the latest safety aspects in mind. Mercedes-Benz thus remains a pioneer in active and passive safety in this segment. The goal is clear: with the CLA, Mercedes-Benz aims to offer the safest car in its class. The new standard safety assistance systems can prevent a variety of accidents. Should an accident occur, the crumple zones, robust passenger cell and restraint systems are designed to minimise the likelihood of serious injury.
New in the CLA and for the first time in this segment, Mercedes-Benz is installing a centre airbag as standard. It deploys between the driver and front passenger in the event of a severe side impact, depending on the severity of the accident and vehicle occupancy. The centre airbag is integrated into the driver's seat backrest.
Proven multi-stage high-voltage protection system and further developed battery early warning system
In addition to protecting the occupants of an electric vehicle as well as other road users, Mercedes-Benz places special emphasis on the protection of the energy storage system. An all-electric vehicle has, in addition to the familiar 12-volt system, a high-voltage system that includes the high-voltage battery and connected consumers, such as the electric motors for the drive and components like the air conditioning. Beyond legal requirements, both the overall vehicle and the high-voltage battery, high-voltage (HV) lines, and other HV components must meet strict Mercedes-Benz standards.
In the all-new CLA, the battery housing is integrated into the crash concept as part of the vehicle structure. Additionally, for the new high-voltage battery generation, Mercedes-Benz has taken comprehensive precautions against potential thermal reactions. These include appropriate spacing between the high-voltage battery cells as wells as adaptations to the structure of the cells and cell modules. The enhanced early warning system not only alerts the occupants but also triggers additional protective measures within the vehicle. These include automatically closing side windows and ventilation flaps. A new sensor, positioned centrally in the high-voltage battery, monitors its status even when the vehicle is parked.
In the CLA, as with other models, Mercedes-Benz has implemented its multi-stage protection concept with eight elements of high-voltage safety. This ensures that there is no danger from electrical components for occupants, first responders and emergency services after an accident. This protection concept has already proven itself in other all-electric models from Mercedes-Benz, confirmed by findings from Mercedes-Benz Accident Research. In the event of a severe accident, the high-voltage system is automatically shut down, with a distinction made between reversible and irreversible shutdown.
Reversible shutdown occurs in minor accidents. If the driver attempts to restart the car after the automatic shutdown, an isolation measurement is automatically performed in the background. A restart is only possible if the system is error-free, ensuring that still-drivable vehicles remain operational. In severe accidents, where the vehicle is typically no longer drivable, the high-voltage system is irreversibly shut down. Irreversible means that only a specialist workshop can reactivate the vehicle.
During automatic shutdown, targeted discharging of the components ensures that they pose no danger. For rescue workers, there are also cut-off points where they can manually de-energise the high-voltage system.
New all-electric CLA reduces carbon footprint by 40 percent compared to its predecessor
The CLA is the forerunner of a new, innovative electric vehicle family from Mercedes-Benz. The carbon footprint of the new all-electric CLA is 40 percent smaller over the entire value chain compared to its non-electrified predecessor. By implementing further carbon-reduction measures in the supply chain and during battery charging, savings can increase to up to two-thirds.
About 40 percent of the aluminium used is produced in electrolysis plants powered by renewable energy, saving a total of approximately 400 kg of CO2 per vehicle for the all-electric CLA. Various carbon reduction measures in the high-voltage cells also reduce the carbon footprint of the new battery generation by about 30 percent per cell compared to the preceding battery. In addition to net carbon-neutral cell production, renewable energy is also used in the production of cathode, anode and cell housing materials.
As well as the interior materials, the thermoplastics in the new CLA also contain a high proportion of secondary materials. This adds up to four times more across the vehicle as a whole compared to its predecessor. A total of 50 percent of the secondary material in the thermoplastics comes from post-consumer recyclate. For example, the jack mounts are made entirely from recycled car bumpers. The frunk well has a recyclate content of around 70 percent.
MB.CHARGE Public: integrated digital charging service
Mercedes-Benz groups all the functions of public charging into the digital extra MB.CHARGE Public (formerly Mercedes me Charge), offering numerous exclusive benefits to its customers. Just one charging contract gives them access to one of the world's largest charging networks. It also ensures they can always charge in the familiar user-friendly way, regardless of station operator. In the all-electric CLA, authentication is via the Mercedes-Benz app, the MB.CHARGE Public RFID card or directly via Plug & Charge at participating charging stations. Each charging process is automatically billed through MB.CHARGE Public. Mercedes-Benz also ensures maximum cost transparency at public charging stations. Before charging, users can view the specific costs per kilowatt-hour or per minute and the estimated total cost for a full charge on the MBUX display or in the Mercedes-Benz app. Additionally, MB.CHARGE Public offers different tariffs and packages with discounted charging conditions depending on the region.
Mercedes-Benz is continuously expanding the charging network through its own activities to build public charging infrastructure worldwide. Around 45,000 charging points will be created by the end of the decade through the global Mercedes-Benz Charging Network and the joint ventures IONITY, IONNA and IONCHI in Europe, North America and China. These will also be accessible via MB.CHARGE Public.
Green Charging: Mercedes-Benz is committed to charging with renewable energy
Green Charging is an integral part of MB.CHARGE Public in Europe, Canada and the USA. If renewable energy is not yet available at the respective charging station, Green Charging uses green electricity certificates. These ensure that an equivalent amount of electricity from renewable sources is fed into the grid for charging processes. These are green electricity certificates from certified energy generation plants that are less than six years old. Wherever possible, the green electricity certificates are purchased and cancelled in the same country where the customer charges. This contributes to the further expansion of renewable energy.
Starting with the new generation of electric vehicles, Mercedes-Benz is extending its Green Charging initiative to private households. With intelligent home charging solutions, private customers can increase the share of renewable energy when charging their electric vehicles via a wallbox and reduce their carbon footprint.
The all-new Mercedes-Benz CLA: high-tech hybrid models with 48-volt technology
All-electric models play a key role in implementing Mercedes-Benz's sustainable business strategy. However, the desires and mobility needs of customers in different regions of the world determine the pace of this transformation. Therefore, the all-new CLA will also be available by the end of the year as a hybrid with 48-volt technology and an electric motor integrated into the transmission. The modular architecture of the CLA model family allows Mercedes-Benz maximum flexibility in the drive concept and production.
Visually, the CLA hybrid closely resembles its electric counterpart, allowing customers to choose between the two drive configurations based on their personal driving profile and usage. One of the few distinguishing features is the CLA hybrid's grille. It has a classic grille with the Mercedes-Benz star pattern in chrome, framed as standard by an LED light guide.
The highly efficient powertrain was developed by Mercedes-Benz engineers in Germany according to proven quality standards. The state-of-the-art combustion engine in the CLA hybrid will initially be available in three power levels. Buyers will have the choice between front-wheel drive and 4MATIC. Technical data and further details, including equipment, will follow later in the year before the sales launch.
CLA hybrid models can drive all-electrically and recuperate
The engine and transmission design is very compact thanks to the cylinder spacing and the side-by-side arrangement of the electric motor. The electric motor, inverter and transmission form a highly integrated unit. A newly developed 48-volt battery with lithium-ion technology offers an energy content of up to 1.3 kWh. Once again, the design is particularly compact: the battery cells and the DC/DC converter are integrated into the flatpack.
The electric motor provides intelligent support across the entire speed range. It significantly improves acceleration, especially at low engine speeds. At urban speeds and when less than 20 kW is needed, the hybrid models can drive using electric power alone. So-called electric sailing, i.e., efficient coasting with a decoupled drivetrain, is possible up to a speed of around 100 km/h. A special feature of the motor is its ability to recuperate in all eight gears, recovering up to 25 kW of energy.
Since the torque output of the combustion engine and the electric motor add up, the maximum torque is available over a wide speed range. Furthermore, the combustion engine can be started entirely by the electric motor and the disconnect clutch, eliminating the need for a conventional pinion starter. The start-stop function and switching between the two motors are almost imperceptible to the driver.
The electric motor, including the inverter, is integrated into a new, very compact eight-speed dual-clutch transmission (8F-eDCT). This development is called "eDCT" because the electric motor is integrated into the transmission, and control of the mechanical system is electrohydraulic. An electric motor serves both lines of the dual clutch. Power transmission and disconnection are achieved via two drive clutches and a disconnect clutch. The wide spread of the eight gear ratios also benefits efficiency, as it enables optimisation of the engine operating points.
New four-cylinder engine from the FAME engine family with Miller cycle combustion process
The combustion engine, developed by Mercedes-Benz, is a four-cylinder petrol unit with a 1.5-litre displacement. The engine, designated M 252, belongs to the Family of Modular Engines (FAME) and is suitable for a variety of vehicle applications.
Common features of the FAME engines include an all-aluminium crankcase with NANOSLIDE® technology and a cylinder head with a partially integrated exhaust manifold. They are also equipped with a turbocharger with a segmented turbine and switchable scroll connection. Other highlights are the compact charge-air path and the exhaust system mounted close to the engine. Its one-box design is prepared for future emission standards. The concept of the electric refrigerant compressor with 48-volt technology, adopted from the M 256, reduces friction and allows the vehicle to be air-conditioned when stationary and during electric driving.
For efficiency reasons, the petrol engine uses a combustion process based on the Miller cycle. The relatively early closing of the intake valves reduces throttling losses and allows a high compression ratio of 12:1. This design helps keep efficiency high and fuel consumption low, especially under partial load, which is very common in everyday driving. This also reduces NOx emissions.
The new engine-transmission unit has compact dimensions and is installed transversely between the steering knuckles. Another advantage is the exemplary NVH behaviour (Noise, Vibrations, Harshness). Conceptually, the M 252 is already at an advantage here because Mercedes-Benz uses four instead of three cylinders. Additionally, the engine has an extensive NVH package of foams and covers to reduce sound radiation. The CLA also features the double-bulkhead concept, known from higher vehicle classes. Furthermore, the bulkhead insulation has been extended into the sides of the A-pillar and the floor.
All-new CLA comes from the Rastatt plant
The CLA models with hybrid drive are produced flexibly on the same line at the Mercedes-Benz plant in Rastatt as their all-electric counterparts. Production is net carbon neutral. The plant is supplied with 100 percent green electricity, most of which is purchased externally.
Rastatt is the lead plant in the production network for Mercedes-Benz vehicles in this segment, serving as a pioneer of the "Digital First" approach in the company's global production network. In preparation for production of the new model, the extensive conversion of an existing assembly hall was virtually represented and commissioned for the first time using a digital twin. The all-new CLA also marks the first series-production applications of the Mercedes-Benz Operating System (MB.OS), the company's proprietary chip-to-cloud architecture. Vehicle software is no longer transmitted via various hardware modules but via a central server of the Mercedes-Benz Intelligent Cloud. In addition to the CLA, the A-Class, B-Class, compact GLA SUV and the all-electric Mercedes-Benz EQA are also produced at the site.
After the gradual ramp-up in Rastatt, Beijing Benz Automotive Co., Ltd (BBAC) will build the CLA for the Chinese market. In collaboration with the Hungarian Mercedes-Benz plant in Kecskemét, further models from the new vehicle family will follow after the start of CLA production.
