The chassis of the Hummer H2 was painstakingly designed and engineered to provide a solid foundation for best-in-class off-road performance, while maintaining a refined, comfortable ride on road. Not only was the chassis specially tuned for superior off road performance, it was actually designed to optimize the off road balance between rock crawling and desert racing. Special attention was paid in areas of obstacle clearance, suspension articulation, wheel control and underbody protection.

Its on road manners, including ride comfort, are extremely refined. The Single Wheel traction control system provides additional capability under certain operating conditions. The system detects a slipping wheel and applies brake pressure to it to slow it down, transferring torque across the differential to provide traction for the wheel on the opposite side. The system senses any slipping wheels and applies the brakes to them individually, while the driveline and differentials transfer torque to the wheel with the high traction for added traction.
