Chevrolet's iconic people and cargo haulers begin a new chapter with the introduction of the all-new 2021 Chevrolet Tahoe and Suburban. Each has been redesigned to be the ultimate SUV - offering the most interior space of any SUV, exclusive technologies and features, and the best driving dynamics in the full-size segment.
Ultimate SUVs built on an all-new chassis
The changes for the all-new Tahoe and Suburban began with a new architecture featuring an independent rear suspension and longer wheelbase. The new architecture targeted improvements central to the needs of full-size SUV customers, including passenger accommodations, cargo capacity, driving dynamics and exterior proportions.
The longer wheelbase and new chassis systems create greater ride smoothness, particularly on uneven pavement and unpaved surfaces, with improved handling. The vehicles' load floors are significantly lower, providing a more natural seating position and a remarkable gain of 10 inches (254 mm) of third-row legroom, with big increases in cargo space.
Suburban: The legend advances with even more interior space
As the longest-running nameplate in automotive history at 85 years, Suburban established the segment and remains a trusted partner for customers who need maximum space. With a 4.1-inch (105 mm) increase in the wheelbase and a lower cargo floor, the new Suburban has the most passenger and cargo space of any SUV. Legroom increases for both the second- and third-row passengers, and maximum cargo volume expands 19 percent while Suburban's overall length increases less than 1 percent.
For the first time, Tahoe and Suburban's second-row seat can slide, adjusting approximately 10 inches (254 mm) forward or rearward. Both the second- and third-row seats also fold more easily, and the load floor is now both flatter and lower than prior models - improving the ease of loading and unloading. The rear-door openings for the Tahoe are also larger, thanks to the increase in wheelbase.
Compromise-free performance
The 2021 Tahoe and Suburban are powered by V-8 engines that are among the most advanced in Chevrolet's history, as well as an all-new Duramax turbo-diesel engine. All are matched with a new 10-speed automatic transmission with electronic shift control.
A 5.3L V-8 rated at 355 horsepower (265 kilowatts) is standard on LS, LT, Z71, RST and Premier models; and a 6.2L V-8 rated at 420 horsepower (313 kW) is standard on High Country. Both feature industry-first Dynamic Fuel Management technology, with more than 12 modes of cylinder deactivation that are designed to optimize engine efficiency across a broad range of driving conditions, including when towing a trailer. The engines also feature automatic stop/start technology, direct injection and variable valve timing, which all contribute to the balance of performance and efficiency.
The optional Duramax 3.0L inline-six turbo-diesel is available on all models except Z71. It is a clean-sheet engine design developed for full-size truck and SUV applications, where torque means everything for confident, on-demand power and trailering capability. The Duramax is rated at 277 horsepower (207 kW) and a strong 460 lb-ft (623 Nm) of torque. No full-size SUV competitor offers a diesel engine. It is expected to give the new SUVs some of the highest fuel economy ratings in the segment.
Highly durable materials make up the 3.0L Duramax's critical components, including iron cylinder liners within the aluminum engine block, a forged steel crankshaft and connecting rods, and blended silicon/aluminum pistons for greater heat resistance and reduced expansion.
Because trailering is important to many full-size SUV customers, the new Tahoe and Suburban include new trailering technologies pioneered by the Silverado pickups. A Max Trailering package is available and includes a high-capacity radiator and cooling fan, an integrated trailer brake controller, a Hitch Guidance with Hitch View feature and the Chevrolet trailering app. Tahoe and Suburban drivers will have up to nine camera views - more than any competitive full-size SUV.
The available features are designed to help improve the trailering experience with easier hitching using rear camera guidelines, bolstering confidence when towing a trailer. Additional features include a trailering app with trailer profiles, trailer tire pressure and temperature monitoring and Side Blind Zone Alert for trailering.
Tahoe and Suburban will have Chevy's industry-first trailering label that is located on the driver's side door jamb. This label provides customers with the information necessary to calculate their vehicle's exact capacities.
Most advanced available suspension in the segment
To improve the driving experience, engineers for the 2021 Tahoe and Suburban developed an all-new chassis that integrates the longer wheelbase spans and the independent multilink rear suspension. In addition, the all-new models offer both the Air Ride Adaptive Suspension system and Magnetic Ride Control - not offered by any competitor - that deliver even greater body control.
"I think the most impressive aspect of the all-new Tahoe and Suburban is how well they handle," said Herrick. "Despite being big, they offer responsive, confidence-inspiring handling that will change expectations for the full-size SUV driving experience."
The independent multilink rear suspension fundamentally transforms the driving dynamics of the Tahoe and Suburban, allowing each rear wheel to handle road conditions separately to dramatically enhance ride quality, steering responsiveness and overall driver control, compared to the previous live axle design.
Tahoe and Suburban's new multilink independent rear suspension, which is composed of three lateral arms, a large longitudinal arm, coil springs and a robust stabilizer bar, offers the ride sophistication and isolating characteristics typically associated with smaller vehicles, but scaled for the superior capability requirements of full-size SUVs.
The Air Ride Adaptive Suspension is available on High Country and Z71 models and delivers automatic load-leveling and ride-height adjustment. The ride-height can adjust up to 4 inches (101 mm). In highway driving, the system automatically lowers the ride height ¾-inch (19 mm) to improve aerodynamics and fuel efficiency. A driver-selectable setting lowers the suspension 2 inches (51 mm) to aid passenger entry and exit when the vehicle is parked. Drivers can also raise the body for additional ground clearance when driving off-road by 1 inch (25 mm) at low speeds in 4WD HI, and an additional 1 inch (25 mm) at lower speeds in 4WD LO.
Tahoe and Suburban feature one of the industry's most sophisticated chassis technologies in Magnetic Ride Control, which is standard on Premier and High Country, and available on Z71. It is one of the fastest-reacting damping systems in the industry, using sensors to continually "read" the road and alter the damping rate of the shocks almost instantly. It reacts much faster than traditional shock absorbers to reduce bouncing, body roll and vibrations that can often resonate in a large SUV.
Expanded range of standard and available safety technologies
Chevrolet is expanding key safety and driver awareness features for the all-new Tahoe and Suburban, with Automatic Emergency Braking standard on all models. A recent study by University of Michigan Transportation Research Institute analyzed the effectiveness of active safety technologies, showing dramatic reductions in certain types of crashes on vehicles equipped with advanced safety features, including a 21 percent reduction in crashes with Forward Collision Alert.
Coming in mid-2020 from Arlington, Texas
The redesigned SUVs go on sale in mid-2020 in North America, with availability in other regions to follow. The all-new Tahoe and Suburban will be manufactured at GM's Arlington, Texas assembly facility, which has received more than $1.4 billion in investments since 2015. The Arlington plant employs approximately 4,800 hourly and salaried personnel, and was recently upgraded with a new paint shop, body shop and additional assembly quality improvements to support the production of the new SUVs.
