2021 Chevy Tahoe Diesel's Skidpad Performance Limited by Top Speed

• GM's full-size SUVs—including the Chevy Tahoe and Suburban, GMC Yukon, and Cadillac Escalade—have intrusive electronic stability control.

• We've had to engage low range on the four-wheel-drive SUVs to disable the stability control system during our skidpad test. Using that method, the best result we've recorded is a lackluster 0.73 g in a GMC Yukon Denali.

• The diesel Tahoe's top speed is limited to 35 mph in 4Low, which led to a pathetic 0.53 g result and the first time a vehicle's skidpad performance has ever been limited by its top speed.

General Motors' new large SUVs are limited by their intrusive stability control systems in our cornering test. Our skidpad test takes place around a 300-foot-diameter circle where we measure average lateral grip while turning both left and right. We test hundreds of vehicles every year, and the results are typically influenced by factors such as tires and the vehicle's weight, and variants of a given model usually perform similarly. But these new body-on-frame SUVs were a bit different.
