Hummer H3 GT Alpha by Geigercars

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!

Press Release

While some are still raving about the most powerful Hummer H3 yet to be designed, others are already a step ahead. The tuning experts at GeigerCars.de have taken the new Hummer H3 Alpha with its 5.3 liter 300 bhp V8 Vortec engine a step further: It has been modified to create improved performance, more driving power, more speed and not to mention its exclusive styling – it is an impressive package both on and off road.

The Hummer H3 GT Alpha achieves its additional power by means of a Geiger Tuning Kit, which raises the engine’s maximum performance to 300 bhp. The engine produces a peak torque of 3876 in-lbs, which allows the 2.3 ton Hummer to effortlessly reach a top speed of 124 mph.

GeigerCars.de has employed three specific components to produce this performance upgrade: software for the engine and transmission, a sport air filter, and a complete stainless steel high performance exhaust system. The distinctive sound emitted from its impressive tailpipes is synonymous with focused power and appeals to even the sportiest of drivers.

Competent off-road, Confident on the road

The H3 Alpha’s four wheel drive makes the vehicle ideal for heavier off-roading, and at the same time allows the H3 to feel at home on the road. GeigerCars.de has modified the H3 with a sport suspension, which lowers the ride height of the SUV to make it suitable for the road and provides a stable and smooth ride when taking fast corners. The Hummer H3 Alpha is easy and safe to drive both on road and off. GeigerCars.de also outfit the vehicle with a high performance brake system providing an additional safety measure- you can be sure that the 2.3 ton H3 Alpha can be steered confidently in every situation.

An extravagant appearance

The H3 GT Alpha’s power and strength is highlighted by its exclusive GT design. Its look is customized, turning the standard Hummer SUV into a truly unique specimen. With racing stripes in any available color, body kits in the car’s chosen color, and black tinted windows- the H3 GT Alpha exemplifies both an extravagant and sporty character. Most impressive is the SUV’s outer appearance boasting 23 inch alloy wheels and 305/35-23 size tires. Alternatively, the vehicle can be equipped with 24 inch wheels and 305/35-24 size tires.

A cinematic atmosphere in the rear

The interior of the H3 GT Alpha is pure luxury with Carbondesign applications and comfortable leather seats. A multimedia system, including both a navigation and sound system ensures a relaxing ride. The cinematic atmosphere provides passengers pure travel enjoyment. Each headrest has an integrated display screen with a personal DVD player.

Improved fuel efficiency using natural gas

For those who are concerned about fuel efficiency and emissions there is the option of converting to the more economical natural gas solution. The H3 Alpha and all other US cars from GeigerCars.de can be equipped with an environmentally friendly natural gas system. Once installed, total carbon dioxide emissions can be reduced by up to 20% and soot particle emission can be reduced entirely. This not only protects the environment but also your pocketbook: 40 Euro and the tank is full! The 75 liter tank has been installed in the rear undercarriage in such a space saving manner that the entire floor space remains unaltered. The Hummer H3 Alpha also reaches its complete performance power when tanking natural gas.
