2021 Chevrolet Suburban Informative Car Review


Chevrolet has completely revolutionized its longest-running nameplate with the 2021 Suburban, and it's larger and better than ever - which is why it was awarded an Editors' Choice award. While there are many similarities between the revamped Chevy Tahoe and this one, extra length plus new independent rear suspension provide even more cargo capacity as well as a third row of seating.

Boasting impressive V-8 engines, a rare diesel option with immense torque, and state-of-the art driver assists alongside of plenty of infotainment features makes the 'Burban one of the biggest SUVs on the market today. The 'Burban is truly an unparalleled competitor to SUV behemoths such as the Ford Expedition Max.

Engine, Transmission, and Performance

The 2021 Suburban offers three distinct engine choices - a 355-hp 5.3-liter V8 as the default choice, an optional 420 hp 6.2 liter V8 or a 277 horse powered diesel 3.0-liter six cylinder engine that produces 460 lb.-ft of torque to match the bigger V8s on offer. All engines are mated with 10 speed automatic transmission and either rear or all wheel drive options while you can also choose to upgrade your experience further by opting for adjustable air suspension and adaptive dampers if desired!

The Suburban's ride height allows for both automated and manual adjustments, making it more accessible to passengers while also providing optimal aerodynamics and ground clearance. If you're seeking sporty styling with features such as blacked-out exterior trim and 22-inch wheels, the RST model i perfect for your needs. As an alternative option, the Z71 trim includes 20-inch wheels outfitted in all terrain tires along with underbody skid plates plus a two speed transfer case that provides traditional four wheel drive capabilities - ideal if you want something rugged looking!

Fuel Economy and Real-World MPG

According to the EPA, the larger Suburban will offer the same fuel economy numbers as the shorter Tahoe, with the 5.3-liter V-8 earning ratings of 16 mpg city, 20 mpg highway, and 18 mpg combined. Stepping up to the 6.2-liter V-8 drops fuel economy only slightly, to 15 mpg city, 20 mpg highway, and 17 mpg combined in rear-wheel drive examples. The optional diesel engine will still likely be the thriftiest, but the EPA hasn't released estimates for that engine yet. Both gas-only powertrains employ fuel-saving technology that includes auto stop/start and cylinder deactivation. Once we're able to test the all-new Suburban models on our 200-mile highway route, we can evaluate their real-world mpg.

Safety and Driver-Assistance Features

The 2021 Suburban features an array of contemporary driver-assistance technologies as well as innovative assists for towing.
