About the Hummer H3

Like the H2, the 2007 Hummer H3 has only one engine option available, a 242hp, 3.7 liter, inline 5 cylinder.  However, the H3 has received an additional transmission.  Instead of just a 4-speed automatic, a 5-speed manual has been added as the standard transmission.  Gas mileage for the 2007 Hummer H3 is pretty low, 15/19 miles per gallon.  Smaller than the other Hummers, the H3 is a slightly more user friendly.  
Most of the features available come standard in the 2007 Hummer H3.  Air conditioning, cruise control, tire pressure monitors and a CD player are just a few of the standard features.  The options include a CD changer, a navigation system and a sunroof.  To keep you safe, the 2007 Hummer H3 has All-Wheel Drive, ABS, traction control and airbags.  Certainly not as high end as the Hummer H2, the H3 is an excellent alternative if you need a more controlled Hummer.
Owners of the 2007 Hummer H3 liked the SUV overall.  A common request was for more power, perhaps a V6 or even a V8 available.  Gas mileage was also a source of contention with owners.  Many owners were surprised by the maneuverability and turning radius of the H3.  Overall, this is a Hummer that is made for people who don't quite need a full-sized beast.  It's been tamed a little bit, and some folks need a calmer ride.
