Overview & Reviews

The Hummer H1 receives a number of important drivetrain improvements this year. Now labeled H1 "Alpha," the truck features a new 6.6-liter turbodiesel V8 good for 300 horsepower and 520 pound-feet of torque. This output is considerably better than last year's 205 hp and 440 lb-ft of torque, and GM says the new engine delivers better fuel economy, too. A new five-speed automatic transmission is also part of the package. It replaces last year's four-speed transmission and delivers a better low-speed crawl ratio and a higher maximum tow capacity. Other supporting changes to the driveline include stronger half shafts, bigger brakes and a new design for the H1's geared hubs that's said to improve smoothness during deceleration and stopping.

• Unsurpassed off-road ability, major-league attention-getter.

• Drives poorly on the street, not much passenger room for such a big vehicle, high price.
