So what does the H1 Alpha offer to those that love to tackle the great outdoors? The real question is what doesn't it have and what does it take to stop the beast. The biggest problem for those like me that don't live in the outback or on a million-acre estate is trying to find a trail wide enough to swallow the H1. I took the truck on some dirt trails just to get an idea of the ride off the pavement.
The Central Tire Inflation System (CTIS) is one of the more unique systems on the H1. An air compressor lives under the hood that can inflate and deflate the front and rear tires to change the pressure based on the terrain and climate conditions. The air compressor can also be used with an extra air hose to inflate other items like bike tires or air mattresses. There is a pressure gauge on the dashboard and two switches to choose inflate/deflate and front/rear tires.
The H1 spends a lot of weight protecting itself from rocks and debris. The rocker panels have shields to absorb impacts. The brushguard is a massive structure to help keep foliage from damaging the front and also helps with keeping tabs of the right front corner of the vehicle when driving.
The undercarriage is completely protected from all you can throw at it. Skid plates, axel shields and fuel tank shields help keep the front and rear covered while a ladder-like frame keeps the engine and transmission free of damage. The H1 Alpha has a massive 16 inches of ground clearance and has a very tall 72 degree approach angle.
Thanks to a sealed central venting system, the H1 can ford 2-? feet of water. The massive grapefruit sized exhaust pipe is located high and at a completely downward angle to stop water from getting in and the air is taken in through a snorkel above the hood.
Running out of gas may turn out to be a difficult thing. The H1 has two gas tanks, a 28.5-gallon main tank and a 24-gallon auxiliary tank. Which tank you are using can be toggled with a switch on the dash. Hummer says the new Duramax engine can power the H1 600 miles between fill ups. What?s that, like 12 mpg?
Suspension is a heavy-duty 4 wheel independent setup with double ?A? frames. The springs on this truck make the ones used on a regular truck like it just came out of a disposable pen. The 4WD system is full-time and uses TorqTrac 4 traction control system. TT4 activates when it senses wheel spin (as long as the brake is not depressed) and will apply the brakes to distribute more torque to the tires that have grip.
ELocker electronic locking differentials are also an option for the H1 Alpha and allow the driver just to flip a switch on the dash to lock and unlock the front or rear differentials to help get more traction.
Once again, the Allison transmission proved its worth driving at low speeds off-road by keeping the truck in first gear. The H1 Alpha wagon has a 9,036 lb towing limit and the tow/haul mode can be used to improve shifting while towing anything that heavy. The transmission also has its own temperature and oil pressure gauge on the dashboard so the driver can always be sure to keep tabs on it.
The H1 has some other impressive climbing attributes: It can scale a 60% slope, a 40% side slope and climb a 22 inch vertical wall. Parking curbs have nothing on that. The capabilities of the Hummer H1 Alpha are no surprise and it still proves to be an awesome vehicle to drive when you remind yourself of the strength and technology underneath you.
