GMC Hummer EV Turning Circle Is Tighter Than Most GM Vehicles

A tight turning circle isn’t a characteristic often associated with large off-road vehicles. But that is all set to change with the upcoming 2022 GMC Hummer EV, which is capable of making some pretty tight turns – tighter, in fact – than most GM vehicles on sale today.

As originally reported by HummerNation.com, there are two figures to consider when discussing the GMC Hummer EV turning circle: the first involves regular two-wheel steering, while the second entails the four-wheel steering.

In two-wheel steering mode, meaning only the two front wheels turn, the Hummer EV turning circle is 44.3 feet or 13.5 meters. With four-wheel steering, meaning all four wheels turn, things get even tighter, enabling the supertruck a turning circle of 37.1 feet or 11.3 meters.

Something to note here is that these measurements are for the turning circle/diameter, not the turning radius, which would only be half of the diameter.

The tight turning circle with four-wheel steering should help the Hummer EV get through the tightest of trail turns that other, similarly-sized off-road rigs would have difficulty navigating without one (or perhaps several) three-point turns. In fact, the Hummer EV turning circle with four-wheel steering is tighter than that of the GMC Terrain and Cadillac XT4, two models that are significantly smaller than the new Hummer.

Not only is the Hummer EV’s turning circle tighter than that of most GM vehicles, it’s also tighter than the turning circle of the Tesla Model 3, something GMC Hummer EV Chief Engineer, Al Oppenheiser, let known during the supertruck’s reveal back in October.

To illustrate how impressive that is, let’s compare the two vehicles’ wheelbases: the Model 3 has a 113.2-inch wheelbase, while the Hummer EV rides on a wheelbase that’s 135.6 inches long. That makes the Hummer EV’s wheelbase more than 22 inches longer, while still managing to have a tighter turning circle. Quite impressive, to say the least.

  1. I had a Quadrasteer GMC Sierra Denali circa 2004-2006. I had to learn how to drive it properly over the course of my first weekend of ownership. When I traded it on a GMC Yukon Denali in ’06 my used Sierra Denali made the cover of the Atlanta-metro edition of Truck Mart. I’ve got a photo of my fiancée holding the magazine, pointing to my ex-truck with a big smile on her beautiful face. She hadn’t wanted me to buy the Sierra Denali in the first place nor transfer to Atlanta so she got her ‘revenge’ after a fashion. The Quadrasteer was an excellent feature. It worked as described and never gave me a bit of trouble. It actually was quite useful for going surf fishing while driving on sand.

  2. Shouldn’t that chart read “4WS” not “2WS”….that’s referring to the steering, right?
