Despite the added power, the 2007 Hummer H3 still feels sluggish. Combine that with the five-cylinder engine’s inherent coarseness, and one must wonder why a smooth V6 with more power and similar efficiency couldn’t be hired for the job. Planting the H3’s throttle begets a lackluster response, while the automatic transmission is relatively smooth, although the shifter is easily bumped from Drive to Neutral. Pilots of the H3 will no doubt notice the truck’s poor visibility and ponderous handling (heightened by our H3X tester’s 18-inch all-terrain tires). To its credit, the H3 offers comfortable front buckets, and braking, while prompting plenty of nose-dive, is sure and effective.
