The all-new 2021 Suburban joins its shorter twin, the all-new 2021 Chevrolet Tahoe at the facility, as well as its corporate cousin – the 2021 GMC Yukon. Both of the short-wheelbase SUVs (Tahoe and Yukon) started production June 26th, 2020, while the long-wheelbase variants (Suburban and Yukon XL) enter production today, July 13th.
With a storied history spanning 85 years, the Chevy Suburban is the longest-running nameplate in automotive history. In fact, it (almost) single-handedly established its segment. The all-new 2021 model was revealed last December and represents the 12th-generation of the Suburban nameplate.
The new model rides on an all-new platform (the GM T1 platform) with a wheelbase that’s 4.1 inches longer than its predecessor, which was in production from the 2015 thru the 2020 model years. There’s also more legroom for passengers riding in the second and third rows.
While 2021 Suburban cargo volume grows 19 percent, overall length of the extended-length full-size SUV grew less than 1 percent. A lower cargo floor makes getting things in and out of the trunk easier and more convenient.
Chevy also made a host of other improvements to the 2021 Suburban, including a completely overhauled exterior, interior, mechanicals, and a bevy of new technologies. An independent rear suspension replaces the live rear axle of the the last-gen, enabling better ride characteristics as well as the aforementioned gains in interior and cargo space.
Six trim levels will be on offer, including the base LS, mid-level LT, sporty RST, offload-oriented Z71, loaded Premier and luxurious High Country. Not all trims will be available during the initial stages of 2021 Chevrolet Suburban production. Particularly, LS and RST will go into production later on in the model year.
The 2021 Suburban will offer three engine options, including two gasoline V8s and a turbo-diesel straight six. The base gasoline engine is the naturally-aspirated 5.3L V8 L84 that’s rated at 355 horsepower and 383 pound-feet of torque. The optional gasoline engine is the 6.2L V8 L87 rated at 420 horsepower and 460 pound-feet of torque. Meanwhile, the 3.0L LM2 I6 turbo-diesel Duramax engine makes 277 horsepower and 460 pound-feet of torque. All three engines are paired with GM’s Hydra-Matic 10L80 10-speed automatic transmission.
The baby Duramax engine will not be available at start of 2021 Chevrolet Suburban production. It will instead join the lineup later on in the 2021 model year. It’s also worth noting that not all engines are available with all trim levels.
With 2021 Chevrolet Suburban production underway, the very first units should be arriving at dealers within the next few weeks, barring any unforeseen delays .
