The 5 Best Off-Road Vehicles

The Hummer H3 Alpha can back up its ostentatious styling. The Alpha designation means more than this smallest of Hummers is equipped with a 300-horsepower V-8 rather than the standard five cylinder. Alphas have a special oil pan that makes sure lubricant flows to the powerplant even as the H3 negotiates a 60-degree incline or a 40-degree side slope. A cast-iron - rather than aluminum - front differential case and more stout front halfshafts handle the engine's huge torque. But power alone won't keep you moving in the back country. The optional locking electronic rear differential and traction control makes sure the tires with the most grip get the most power. Also optional is a 4.03:1 low range transfer case, while available 33-inch diameter tires help the H3 clear obstructions.
