ForbesAutos.com has reviewed the 2006 Hummer H3, the new smaller Hummer. Forbes says the H3 handles better than the other Hummers but the gas mileage is still not good.
GM did its best to make the H3 fuel-friendly, equipping it with a relatively small (3.5 liters) 220-horsepower, five-cylinder truck engine (from the Chevy Colorado/GMC Canyon). It doesn't help much, though. Our 300 miles of untrafficked rural-road and interstate driving gave a bottom line of 14.7 miles per gallon. The full-time all-wheel drive and 4,700-pound curb weight are among the culprits for such a high rate of fuel consumption.
Autoweek reports that there is also a Hummer H4 coming out in 2008 or 2009 that aims to be a "a rough-and-tough competitor for the Jeep Wrangler."
