For those who think the current five-cylinder Hummer H3 powerplant just doesn't have enough juice, Hummer has dropped a V8 into the 2008 Hummer H3. It will be called the H3 Alpha and it goes on sale this summer. (the V8 is an option)
The lump in question is a 5.3-liter, small-block V8 making 295 horsepower and 317 pound-feet of torque. The H3 Alpha, which comes with a four-speed automatic transmission should get to 60 mph from a standstill in about 8 seconds. That's a 3 full seconds quicker than a standard H3. Hummer says it doesn't have any fuel economy estimates for the new model.
All Alphas come standard with a higher level of standard luxury features and have many bits of chrome trim and wheels along with "Alpha" badging.
