It must be 30 degrees although it looks like 45 as the Hummer noses down it. It has been raining and the first attempt to climb back up the grass, from a standing start mind you, does not quite succeed. The second attempt, with a bit more welly, is successful. The automatic transmission and the torque-biasing differential certainly make it easy for the driver. The wheel track is a shade under 6' - 71.
Suspension is independent with double wishbones and coil springs at each corner.
The transmission is also cleanly tucked up between and above the chassis rails. Braking is by in-board mounted discs. The air line is carried down the centre of the non-rotating stub axle and there is a seal and air hose to the tyre valve on the outside of the wheel, another advantage of portal axles with hub reduction gearing. A similar arrangement is used by some Unimogs. The Hummer is the absolute antithesis of the Jeep, the Land Rover, the European style of military four wheel drive.
