On-road Performance Meets Off-road Legend. by Don
 — 20mpg after the chip tune. My only complaint is the cruise control. The cruise control PID loop needs to be retuned to not let the motor go above 6krpm. Everything else about this vehicle is SOLID. ... Read More

2007 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.  ItâÂ?Â?s been tamed a little bit, and some folks need a calmer ride.
