What is the actual fuel consumption of the Hummer H3?
3 Answers
The actual fuel consumption of the Hummer H3 ranges from 11.7 to 14.6L. Taking the Hummer H3 2008 H3x 3.7 as an example, its body dimensions are 4782mm in length, 1989mm in width, and 1904mm in height, with a wheelbase of 2842mm. The body structure is a 5-door, 5-seat SUV, and the minimum ground clearance is 216mm. The Hummer H3 is equipped with a 3.7L naturally aspirated engine, delivering a maximum horsepower of 245ps, a maximum power of 180kw, and a maximum torque of 328nm. It is paired with a 4-speed automatic transmission, featuring a front-engine, four-wheel-drive layout. The front suspension type is a double-wishbone independent suspension, and the rear suspension type is a torsion beam non-independent suspension.
I've been driving a Hummer H3 for five years, and this car is indeed a gas guzzler. In city traffic jams, it consumes around 20 liters per 100 kilometers, while highway cruising can drop it to about 15 liters. It mainly depends on how you drive—aggressive acceleration and braking can easily push it to 22 liters. With a 3.7-liter engine paired with a 2-ton body, it guzzles fuel even when starting from traffic lights. Once, a friend took the same model off-roading, and the fuel gauge visibly dropped while climbing hills, reaching up to 25 liters on dirt roads. With fuel prices so high now, you'd better budget an extra 2,000 yuan per month for gas if you drive this car. Modifications like spare tires or extra roof racks will make it even thirstier.
Just sold a 2010 H3, having handled over a dozen of this model. Real-world fuel consumption typically ranges between 17 to 22 liters. The 5.3L V8 version consumes 3 liters more per 100km than the 3.5L variant. Cold starts in winter are particularly fuel-intensive, reaching up to 30 liters in the first ten minutes when temperatures are below freezing. I recommend owners use 95-octane fuel, as 92-octane often triggers the engine warning light. Tire size has a significant impact—factory tires consume 15 liters on highways, while switching to off-road tires increases it to 18 liters. The rear-wheel-drive version saves about 2 liters compared to the four-wheel-drive, but let's be honest, who buys this car if not for its all-terrain capability?
