The Hummer H3, introduced in 2005, was a compact sport utility vehicle (SUV) produced by General Motors (GM) under the Hummer brand. It was designed as a more affordable and maneuverable alternative to the larger Hummer H1 and H2 models, aimed at appealing to a wider range of buyers seeking a rugged and capable off-road vehicle. The H3 was based on the GMT355 platform, also shared with the Chevrolet Colorado and GMC Canyon pickup trucks, providing a strong foundation for its off-road prowess. It featured a distinctive boxy design, offering a commanding driving position and ample interior space for five passengers. The 2007 model year saw several updates to the H3, including a revised grille design, new exterior colors, and improved interior trim.

Powering the 2007 Hummer H3 was a 3.7L Inline-5 engine, producing 242 horsepower and 242 lb-ft of torque, mated to a 4-speed automatic transmission. The H3 was available in both 2WD and 4WD configurations, with the latter featuring GM's shift-on-the-fly 4WD system for effortless transitions between driving modes. The H3's off-road capabilities were further enhanced by its high ground clearance, rugged suspension, and available optional features such as locking differentials and skid plates. It was designed to handle challenging terrain and provide a capable and confident driving experience, making it a popular choice for enthusiasts looking for an adventure-ready SUV.
