2006-2008 Hummer H3: Overview

Vehicle Highlights

General Motors-owned Hummer fielded its first midsize sport-utility vehicle for 2006, ready to compete against the Ford Explorer, Jeep Grand Cherokee, and Toyota 4Runner. Seating five passengers, the H3 shared a powertrain and truck-type body-on-frame architecture with GM's midsize Chevrolet Colorado and GMC Canyon pickup trucks. Compared to Hummer's H2, the H3 was 11 inches shorter in wheelbase, 3.3 inches shorter overall, 6.5 inches wider--and 1700 pounds lighter. Sole engine was a Vortec 220-horsepower inline five-cylinder, mated to a five-speed manual transmission or a four-speed automatic. This was the first Hummer to offer a choice of transmissions. Each H3 came with all-wheel drive that included low-range gearing. An H3 could ford 16 inches of water at 20 mph, according to Hummer; 24 inches if slowed to 5 mph. Ground clearance was 9.1 inches, and the H3 could climb 16-inch vertical steps and rocks. An available Adventure Off-Road Suspension Package included special suspension tuning, ultra-low transfer-case gearing, and a locking rear axle. All H3s had antilock four-wheel disc brakes, tire-pressure monitor, and StabiliTrak traction/antiskid control. Available but not standard were head-protecting curtain side airbags with rollover deployment. All H3s also had split folding rear seats, 16-inch alloy wheels, underbody shielding, and a swing-open rear cargo door with fixed glass and outside-mounted spare tire. Also standard was GM's OnStar assistance. Options included a sunroof, leather upholstery, heated front seats, and satellite radio.
