All 2009 Hummer H3T models come with full-time four-wheel drive with a two-speed transfer case. All except the Alpha are powered by a 3.7-liter inline five-cylinder engine that makes 239 hp and 241 lb-ft of torque. The standard transmission is a five-speed manual, and a four-speed automatic is optional. Although the five makes decent power, it’s simply outmatched by the H3T’s near-5,000-pound mass, so acceleration is leisurely at best. Towing capacity is rated at 4,400 pounds when properly equipped, and EPA fuel economy estimates stand at 14 mpg city/18 mpg highway and 15 mpg combined with either transmission.

The Alpha features a 5.3-liter V8 (with 300 hp and 320 lb-ft of torque) mated to a four-speed automatic transmission. Towing capacity goes up to 5,900 pounds, and we’d expect its performance to be about the same as the H3 Alpha, which sprinted from zero to 60 mph in a relatively quick 8 seconds flat. With this engine, fuel economy drops slightly to a 13/16/14 mpg rating.
