GMC Hummer EV: Zero Emissions, Zero Limits

May 17th, 2021 by

The GMC Hummer EV Pickup continues to go through rigorous off-road testing in the lead-up to its production debut this fall.

The most recent test took place on the challenging trails near Moab, Utah, where the Hummers off-road capability was put to the test. The teams testing and calibration included Adaptive Air Suspension hardware, Extract Mode, Terrain Mode, One-Pedal Driving control, e4WD and torque distribution, eLockers, stability control, rear steering, CrabWalk and more.

“GMC’s Hummer EV SUV offers an exceptional balance of on-road performance and off-road capability, enhanced by a unique structure that allows for our signature open-air experience,” said Al Oppenheiser, Hummer EV chief engineer. “New features debuting on the SUV reinforce its role as a tactical tool in almost any situation.”

Available Terrain Mode, part of the GMC Hummer EV’s Drive Mode Control, will offer two braking calibrations with a mild braking option for two-foot driving and a purpose-designed One-Pedal Driving control in low-speed off-road driving.

One-Pedal Driving enables the driver to accelerate and decelerate using only the accelerator pedal. With Terrain Mode, that same One-Pedal Driving control is adapted with unique calibrations for speed-limited off-road driving, helping the driver to negotiate steep grades, rock crawling and other challenging terrain without having to toggle between the accelerator and brake pedal.

“One-Pedal Driving offers a great feeling of control by optimizing the regenerative braking, friction braking and drive motor torque all through the accelerator pedal,” said Aaron Pfau, GMC Hummer EV lead development engineer. “Drivers will quickly realize the benefits once they try it off-road.”

The upcoming available Extract Mode feature enables the Adaptive Air Suspension height to be raised approximately 6 inches in order to help the GMC Hummer EV navigate extreme off-road situations, such as clearing large boulders and deep water.

“The GMC Hummer EV was a blank slate that was filled out by a dedicated team of engineers who are hardcore off-road enthusiasts,” said Pfau. “Features like One-Pedal Driving, Terrain Mode and Extract Mode result in an absolute off-road beast that will take you to new places.”
