Chevy totally reinvents its oldest nameplate with the all-new 2021 Suburban—and it’s bigger and better than ever, which earned it an Editors’ Choice award. It shares a lot with the redesigned Chevrolet Suburban; however, its extra length and newly adopted independent rear suspension bring more cargo and third-row space. Those traits make the ‘Burban the biggest SUV to wear a bowtie, and a serious competitor to enormous alternatives such as the Ford Expedition Max. In addition to its familiar V-8 engines, the Chevy now includes a diesel option with loads of torque. Of course, it also offers an abundance of obligatory equipment such as contemporary driver assists and countless infotainment features.
The 2021 Suburban introduces an all-new generation that features significant improvements. The most notable update is the SUV’s first-ever independent rear suspension. This allows much better interior packaging that frees up room in the cargo area and third row. The Suburban is also longer than before and outfitted with more technology than ever. This includes first-time equipment such as an air suspension and a downsized Duramax diesel engine. We’d recommend the RST model. Unlike before, it’s no longer the high-priced, high-performance Suburban. Instead, it’s mostly a sporty appearance package that also can be equipped with the diesel engine. We’d choose the latter to replace the standard 355-hp V-8 and add all-wheel drive.
A pair of V-8s and a diesel six-cylinder complete the Suburban’s engine lineup. All of them hook up to a 10-speed automatic transmission and either rear- or all-wheel drive. A 355-hp 5.3-liter V-8 is the default engine on all but the top-tier High Country model. It gets a standard 420-hp 6.2-liter V-8, but it also can be equipped with the optional diesel 3.0-liter six-cylinder engine. While the latter only pumps out 277 horses, its 460 lb-ft of torque ties that of the bigger V-8. The 2021 Suburban also can be fitted with adaptive dampers and an adjustable air suspension. The latter allows the Suburban’s ride height to be automatically and manually lowered or raised. This enables improved passenger accessibility, aerodynamics, and ground clearance. Those looking for sporty styling such as blacked-out exterior trim and 22-inch wheels should see the RST model. The more rugged-looking Z71 trim level has 20-inch wheels wrapped with all-terrain tires, underbody skid plates, and a two-speed transfer case that provides traditional four-wheel drive.
