Hummer EV Software Update Adds 6-Inches of Ground Clearance
GMC managed to increase the ride height of the Hummer EV with an over-the-air software update.
The update unlocks a new feature on the electric pickup called "Extract Mode." Once installed, it's possible to raise the Hummer "nearly 6 inches above normal ride height," which is achieved using the vehicle's Air Ride Adaptive Suspension system.
Extract Mode isn't something GMC expects you to use often. It's available to help clear obstacles when off-roading and is limited to low speeds. Until now the ground clearance available maxed out at 11.9-inches in Terrain Mode, but Extract Mode extends that to 15.9-inches.
The new mode also means many of the other off-road specs improve: the approach angle is now up to 49.7 degrees (previously 44.3 degrees), the departure angle 38.4 degrees (previously 33.7 degrees), breakover angle 32.3 degrees (previously 25.4 degrees), and water fording 32-inches (previously 28-inches).
To enable Extract Mode(Opens in a new window), locate the ride height controls on the Driver Mode Control dial on the center console, select Terrain Mode by rotating the dial, and then press the Raise button. Extract Mode should appear on the Driver Information Center, but it may take multiple button pushes before it appears. To revert back, press the Lower button instead. GMC cautions that frequent use of the air suspension system may result in a cooling period being required before you can drive again.
