2007 HUMMER H3 Review

All-day comfort and good off-road capabilities.

Reviewed by Automotive on


The 2007 Hummer H3 is well-suited for narrow trails like its brother, the H2, but in some ways the H3 is a more reasonable purchase. The GMC Canyon and Chevrolet Colorado pickup platform is utilized with the same five-cylinder and combined to make the Hummer H3 one of the top picks in the SUV category. 2007 marks an improvement in output with an increase of 242 hp that bumps the torque to 242 lb-ft.

The four-wheel drive works full-time, which allows the SUV to climb and depart the serious trails without trouble. The ground clearance and standard skid plates give the H3 an advantage over the H2 and the rest of the competition. With the 4700-pound H3, some drivers feel that a V-8 or V-6 could improve the sometimes sluggish feel of the SUV. As for the off-road capability and impeccable image, it looks to be an excellent choice in the SUV segment.

The Range

Body Styles: SUV
Engines: 3.7-liter five-cylinder
Transmissions: four-speed automatic, five-speed manual

What's New

Both functional and visual changes have been made to the 2007 Hummer H3. A new model, the 2007 Hummer H3 H3X, gets chrome accents on wheels and brush guards, unique colors, and embroidered headrests. Powertrain warranty was extended, the engine became more powerful, and stability control became a standard feature for 2007.


When it comes to the 2007 Hummer H3 exterior, most people recognize the unique styling cues of the traditional Hummer. The standard 2007 Hummer H3 models come with 16-inch alloy wheels, full skid plates, rear window wiper, and rear defogger. The 2007 Hummer H3 H3X model has a fancier feel with the addition of 18-inch chrome wheels, chrome accents, brush guards for grille and headlights, tube running boards, and privacy glass. The available packages can add off-road suspension, locking rear differential, and 33-inch off-road tires.


This 2007 Hummer H3 has many interior standard features that include a CD six-speaker stereo, full power accessories, keyless entry, cruise control, air-conditioning, and OnStar telematics. The 2007 Hummer H3 H3X edition adds leather seating, CD changer, Monsoon audio system, heated front seats, and power front seats. Packages for enhancement offer leather upholstery, satellite radio, navigation system, and six-disc in-dash changer.

Having one of the best types of layouts among GM vehicles, the 2007 Hummer H3 has a lot of style and class inside. When riding in the large SUV, the feel is comfortable and sophisticated with metallic accents, two-tone scheme of colors, and leather optional seating. Cargo capacity is fair with 55.7 cubic feet, and the legroom for rear passengers is ample.

Performance & Handling

Boosting the 2007 Hummer H3 power was a refreshing addition with the inline five-cylinder, 3.7-liter engine producing 242 hp with 242 lb-ft torque. It sends power to all of the four wheels via the manual five-speed on standard base models, whereas the automatic four-speed can be selected as an option. The output is respectable, though the heavy weight takes a toll on acceleration and performance. The towing capacity is great at 4500 pounds, and the fuel economy is sufficient for the size of vehicle.

While driving the 2007 Hummer H3, the punch is sufficient at low speeds of city driving, though the H3 feels a bit winded and sluggish during freeway merging and on inclines. For off-roading, the 2007 Hummer H3 is about the best there is. The ground clearance of nine inches and aggressive approach with the all-terrain oversized tires, the 2007 Hummer H3 can go almost anywhere it pleases. When taking family road trips, the ride is comfortable and smooth for all passengers.


2007 Hummer H3 standard safety features include anti-lock brakes, OnStar system, monitoring tire-pressure, and stability and traction control. An optional feature is curtain airbags that are full-length. In impact testing by the National Highway Traffic Safety Administration, the Hummer H3 received five stars for driver and four for front occupant in frontal crashes. It also received five stars in side crash testing without curtain airbags.
