Performance & Capability

Engine Options

The Suburban is all about giving you choices on what kind of powertrain you want out of this fully capable SUV. Two V8 options are available in the 5.3L EcoTec3 V8 (with 355 horsepower and 383 lb-ft of torque) and the 6.2L EcoTec3 V8 (with 420 horsepower and 460 lb-ft of torque), both with 10-speed automatic transmissions. For those who prefer the diesel side of things, a Turbo-Diesel engine is available, with the Duramax 3.0L (with 277 horsepower and 460 lb-ft of torque).

Four-Corner Air Ride Adaptive Suspension

Those driving on the Z71 or High Country Suburban trims will enjoy the first-in-class Four Corner Air Ride Adaptive Suspension. What this advanced system does is automatically adjust the ride height and ride comfort to match the conditions around you. For when you need to clear obstacles at a high height, or keep the body lower for aerodynamic purposes, the Suburban is versatile for your wide-ranging needs.


Head-Up Display

Modern technology like this Head-Up Display allows you to be able to keep your eyes on the road, but still be apprised of everything going on in your vehicle. This 15-inch multi-colour display on your windshield projects info like calls, safety alerts, directions and more.

9 Camera Views

The Suburban has space for a lot of people and eyes, but if it’s just you or you need some extra help on any drive, the class-leading nine available camera views will help you maneuver the large body of the Suburban without hassle.

Trailering Tech

This full-size SUV can take passengers and cargo inside, but is still fully capable to tow as well, with an abundance of trailering technology to make your latest towing trip a breeze. Available is the Advanced Trailering System, complete with an in-vehicle app that includes checklists, tire/temperature monitoring and custom profiles.


Forward Collision Alert

For any vehicle you’re following, this Forward Collision Alert will detect if a front-end collision may be imminent, allowing you to quickly adjust. This system also happily provides you with a tailgate alert when you get too close to the vehicle ahead.

Automatic Emergency Braking

Working in tandem with the Forward Collision Alert is this Automatic Emergency Braking, activating at speeds below 80 km/h. Its camera tech provides emergency braking, or assistance of the driver’s braking, to help reduce the severity of collisions.

Front Pedestrian Braking

It’s not just vehicles that the Suburban is aware of, but pedestrians, too. This system is active during the daytime and at speeds less than 80 km/h, with only limited nighttime visibility. It will provide emergency braking or help your own braking from a collision with a pedestrian.

What’s New From the 2020 Chevrolet Suburban?

The 2021 Chevrolet Suburban touches down with an all-new generation from the 2020 model year. This fully redesigned model is one of the biggest SUVs yet in Chevy’s arsenal, built on a truck frame that’s made to create the equally legendary Silverado 1500. Added space is introduced in the form of rear legroom and cargo room, along with more refined elements inside. The all-new 2021 Suburban offers an even smoother ride thanks to its first-time-ever independent rear suspension. New, as well, is the Duramax diesel engine option for even more powertrain availability.
