The tuning experts at have taken the new Hummer H3 Alpha with its 5.3 liter 300 bhp V8 Vortec engine a step further

Massive horsepower

The Hummer H3 is still the baby Hummer, shorter, less powerful but also lighter than its bigger brothers the H1 and H2. German Hummer experts Geigercars have successfully tuned up the H2 to be the fastest Hummer on the planet with a whopping 700 hp and a 0 – 100 km/h time of 6.5 seconds.

Time for the H3 to receive a similar treatment. The 2.3 tonne SUV has had its 5.3 liter V8 Vortec engine remapped through the Geiger Tuning Kit to produce 300 hp (instead of the factory 242 hp). The Tuning Kit consists of new engine software, a sport air filter and stainless steel performace exhaust system, resulting in a top speed of 124 mph. The sport suspension lowers the H3, improving its road going behaviour while not impeding its off-road abilities too much. A performance brake system ensures that there is enough stopping power available to keep driving this little monster safe.

The exterior has received it own fair share of upgrades with a very distinctive GT design. The racing stripes are available in any color and the body kit in the car's chosen color. There is a choice of 23 (305/35-23) or 24 (305/35-24) inch alloy wheels.

Inside you will find leather seats, plenty of carbondesign applications and full blown multimedia system with personal DVD players in every headrest. Interestingly enough Geigercars also has a natural gas kit available for the gas guzzler, lowering carbon dioxide emissions by 20% while the 75 liter gas tank can be refilled for just EURO 40, without sacrificing its performance increase!
