2010 HUMMER H3 is a 5.3 Liter V8 engine that boasts an impressive 300 horsepower and nearly 320 pound feet of torque. Paired with the 4 speed automatic transmission, the combo can tow an impressive 6,000 pounds with ease. The fuel economy that is characteristic of the 5.3 Liter V8 engine is less than most drivers would like and is estimated to be about 13 miles per gallon in the city and 16 miles per gallon on the highway. However, it is important to realize that a lot of the fuel economy is more of a result of the sheer heaviness of the vehicle and cannot be solely blamed on the engine.

The standard engine is a 3.7 Liter V5 motor that delivers 239 horsepower and 241 pound feet of torque. Either the five speed manual transmission or the 4 speed automatic transmission are matched very well with the engine and the combination is sure to please most individuals. While most individuals that tow large items are going to be more interested in the larger engine, the standard motor can easily handle weights of up to 4,500 pounds. The most significant advantage of the 3.7 Liter V5 motor is that the fuel economy is better than that of the larger engine and is estimated to be about 14 miles per gallon in the city and 18 miles per gallon on the highway.

In road tests of the 2010 H3, nobody was impressed with the fact that the mammoth could somehow accelerate up to 60 miles per hour in 11 seconds from a pit stop.

Luckily, it is also available with Alpha edition of the H3 that supports a 5.3-liter V8 engine to the generation of about 300-hp, and provide more decent performance. The 2010 H3 attains the speed of 60 mph in 8.8 seconds, with the help of V8 engine. The 60/40-split back seat can be folded to enhance the cargo space, even though the maximum capacity of the vehicle is of 56 cubic feet is lower than that of a lot of medium sized and compact SUVs. Exterior visibility is pretty weak with the tailgate-mounted additional tire and gun-slit-style windows.
