Speaking to GM Authority at the recent reveal event for the new Chevy SUVs, GM Vice President of Global Product Programs, Tim Herrick, confirmed the Tahoe and Suburban have gained weight over the outgoing K2 platform models, though he wouldn’t say by how much.
“We’re not announcing weights yet, but these will be a little heavier [than the outgoing, K2 models]” Herrick, told GM Authority executive editor, Alex Luft.
This is a bit surprising, as the Chevrolet Silverado and GMC Sierra both lost weight when they moved to the T1 platform in 2019, which the Tahoe and Suburban also use. When comparing the Crew Cab V8 models, the current-generation Chevrolet Silverado is 450 pounds lighter than a previous generation K2 Silverado.
At the same time, the Chevrolet Tahoe and Suburban are both considerably larger than before. The 2021 Tahoe has a wheelbase that is 4.9-inches longer than the outgoing model, while the Suburban’s wheelbase has grown by 4.1 inches. They also have much more cargo space than in years previous, with the Tahoe’s cargo volume growing by a considerable 66 percent in total.
Some weight has also been tacked on with the new multi-link independent rear suspension. The automaker estimates the more sophisticated suspension setup is 50 to 100 percent heavier than the old live rear axle depending on the model, though it believes the added weight is a worthwhile trade off for improved ride and handling and better packaging.
Speaking of better packaging, both the Tahoe and Suburban have gained a massive 10-inches of third-row legroom – fixing one of the biggest problems with the outgoing K2 models. With a comfier ride and more space for them and their things, customers probably won’t mind having a few extra pounds onboard, and we think most probably won’t notice it.
The 2021 Chevrolet Tahoe and 2021 Chevrolet Suburban will go on sale in mid-2020 in the North American market.
