2021 Chevrolet Suburban and Tahoe Debut with Diesel Power and IRS

The Chevrolet Suburban and the slightly shorter Tahoe have generally followed suit with the automaker’s full-size pickup line. We got an all-new Silverado for the 2019 model year, and now it is time for Chevy’s big SUVs to evolve.

The obvious upgrade comes with the SUVs new suit, which draws heavily on the Silverado’s controversial styling. LED lights are standard front and rear, along with 18 inches wheels and 20 inches wheels are optional. Both SUVs will offer nine exterior shades at launch, and if they look a bit bigger, it is because they are. The Suburban’s wheelbase is stretched 4.1 inches and is 1.3 inches longer overall. The Tahoe expands even more – its wheelbase now spans an extra 4.9 inches and bumper-to-bumper distance grows by 6.7 inches.

The Bow Tie twins do not ride on carryover underpinnings. Both SUVs are all-new underneath and there is a major upgrade in the form of a multi-link, independent rear suspension. The solid axle is gone and that should translate to a smoother ride for all seven passengers inside. The company’s Magnetic Ride Control and Air Ride Adaptive Suspension are available options to further enhance the ride, and the new underpinnings also give the Tahoe and Suburban a lower floor height for easier loading. Whether or not this affects the SUVs maximum tow rating is unknown, though a distinct lack of towing statistics from Chevy suggests it might be worse.

The new suspension and stretched wheelbase also translate to more space inside. For the shorter Tahoe, cargo space behind the third row increases by a full 66 percent. There is 122.9 cubic feet of storage all total, and while space in the Suburban was never really an issue, it gains 19 percent in back for a total cargo capacity of 144.7 cubic feet. With regard to passengers, third-row riders in the Tahoe get 10 more inches of legroom while Suburban passengers get approximately two extra inches in the second and third row to stretch out. Both models now feature sliding second-row seats for easier access to the back as well.

Passengers get more technology in the new Bow Tie SUVs as well. As many as five displays are available, including a standard-issue 10 inches infotainment screen that Chevrolet says is the largest in the segment. An optional digital instrument cluster is among them, along with a big head-up display and two 12.6 inches LCD displays for rear-seat passengers.

For safety and convenience, Chevrolet is keen to wax poetic about 30 various features, but included in that lofty number are decades-old staples like airbags and seat belts. There is some modern technology, however, including standard-issue automatic emergency braking for all Tahoe and Suburban trim levels. A bevy of cameras, collision alerts, pedestrian alerts front and rear, and other upgrades are available, too.

Under the hood, the familiar 5.3 liter V8 carries over as the standard engine, still packing the same 355 horsepower. The 6.2-liter, 420 horsepower V8 also carries over as the up-spec engine. The new 3.0-liter Duramax turbo-diesel inline-six joins the options list, offering an estimated 277 horsepower and 623 Newton meters of torque. The engine is now connected to a standard 10-speed automatic transmission. Fuel economy figures are not yet available for any of the engine options, including the diesel.

The pricing is not yet available, but we can tell you that a new High Country model level joins the ranks as the range-topping trim beyond the Premier edition.

The 2021 Suburban and Tahoe will hit dealerships in mid-2020.
