The Secret Ingredient That Makes Super-SUVs Handle Like Sports Sedans

The brain can’t make sense of it. Watching it gums up the pattern recognition machine at the center of our gray matter. Years of experience and reinforcement have provided an accurate model of how a big, high-riding, comfy SUV will flop itself around a corner. At the wheel of the 2021 Bentley Bentayga, that prediction is always wrong. The calculus in your neurological filing cabinet won’t add up when it comes to machines like this.

This is endemic to the whole fleet of modern super-SUVs. It goes beyond the supercar/sports sedan more-grip-than-you-can-comprehend phenomenon, because it’s more than just an increase in capability. It is a fundamental shift in how vehicles handle their weight.

The culprit is the active anti-roll bar. It’s the single element that allows the Lamborghini UrusAston Martin DBXPorsche Cayenne Turbo, Bentley Bentayga, and Audi RS Q8 to corner flat and still ride well. A traditional anti-roll bar has a set stiffness; stiffer bars allow flatter cornering but also tie wheel motions together and amplify bumps. A softer setup will improve comfort, but won’t be able to resist body roll. For the full story, check out this article from Road & Track.
