Three refined engine options are available for the 2021 Chevy Suburban. For specifics on each of these choices, read on below!

2021 Chevy Suburban rear/side view5.3-Liter V8

The 355 hp 5.3-liter V8 engine comes standard in the 2021 Chevy Suburban. It does a great job zipping around town, and can accelerate up to highway speed with minimal strain. Partly to credit for the enjoyable, power-ready drive the engine provides is the delightfully quick, decisively shifting 10-speed transmission; this gizmo always has plenty of power on tap ready to be unleashed.

6.2-liter V8

The 420 horsepower 6.2-liter V8 provides everything drivers need to turn their drive into a bona fide blaze of glory. This hot and spicy offering maneuvers the big SUV effortlessly, even with big loads being hauled behind. When the pedal is pushed down, a satisfying exhaust roar is emitted. Note that this engine is only offered on the High Country trim.

3.0-liter Duramax Diesel

The 277 hp 3.0-liter diesel engine, lovingly referred to as “Baby Duramax,” is a likewise great option. It provides brisk, smooth, quiet acceleration. This last detail is particularly impressive, as diesel engines are known to be noisy in general.

Electronic Gear Selector

One unique performance element of the 2021 Suburban is the electronic gear selector mounted on the dash. Buttons and switches are used to switch gears, rather than a shift stick. Park and neutral can be toggled with buttons, while switches are pulled to engage drive and reverse.
