2006 Hummer H1

The 2006 Hummer H1 is a full-size SUV available in traditional and convertible body styles, both with four seats. The H1 is for drivers who want a large, attention-grabbing SUV that shines off-road.

Hummer equips all H1 vehicles with a 6.6-liter turbodiesel V8 that produces 300 horsepower and 520 pound-feet of torque. Power is sent to all four wheels through a 5-speed automatic transmission.

The H1 is in its element when driven off-road. With 16 inches of ground clearance and a low-geared drivetrain, it can handle whatever stands in its path. Adding Hummer’s Off-Road Adventure package makes this SUV even more trail-ready, adding front and rear Eaton E-Locker differential locks, special 17-inch wheels, and a 12,000-pound winch.

Bold styling sets the H1 apart, turning heads on city streets and in parking lots. This SUV also has a stout tow rating, pulling up to 9,303 pounds.

The H1 won’t be a great fit for all buyers. It feels coarse on paved roads, where some other full-size SUVs deliver greater refinement. Also, it has less passenger and cargo room than other vehicles in its class.

What’s New in the 2006 Hummer H1?

• New, more potent turbodiesel V8.

• New 5-speed automatic transmission.

• Improved tow rating.
