View all Hummer H3 reviews
Parkers overall rating: 2.5 out of 5 2.5

With prices starting at a little less than the cheapest Land Rover Discovery, the Hummer looks decent value. For a petrol 4x4, depreciation is relatively slow, however fuel consumption is punishing. With only one official dealer at the time of the H3's launch, customers will also have to travel for servicing. However, the H3 has a longer than average warranty at four years/60,000 miles should anything serious go wrong.

Only one petrol engine is available with the H3 with CO2 emissions of 327g/km or 346g/km, depending on whether you choose the standard manual or optional automatic. While these figures are quite high, they are no higher than expected for a petrol 4x4 of this size. Fuel economy is poor though, the Hummer only returning 20mpg with the manual and 15mpg with the automatic.

Although the engine is new for the H3, most other parts are proven and the technology is relatively simple. The car should prove generally reliable.
