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. This was achieved through a complete transformation of Chevrolet's full-size SUVs, combining the strongest aspects of its new full-size truck architecture with entirely new systems tailored to the needs of today's SUV drivers and passengers.
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.
Tahoe: The leader expands with 66 percent more cargo space
Already America's best-selling full-size SUV, accounting for more than 25 percent of the segment, the redesigned, fifth-generation 2021 Tahoe features substantially more usable space. With a 4.9-inch (125 mm) longer wheelbase and a 6.7-inch (169 mm) increase in overall length compared to the current model, Tahoe offers 40 percent more third-row legroom and 66 percent greater cargo volume behind the third row. The space gain is achieved efficiently; while maximum cargo room increases 30 percent, Tahoe's overall length increased less than 4 percent. The 2021 Tahoe offers 25 percent more cargo room behind the third-row seat than the 2020 Ford Expedition (20.9 cubic feet).
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.
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.
