July 12, 2006 Born from a military vehicle and the most prominent symbol of America's global military dominance, the HUMMER does not require more testosterone, but hey, boys will be boys. German automotive performance house Geiger specialises in American cars and outrageous one-offs, and is hence accustomed to unusual customer requests. So the request from a Texas sheriff to turn his personal emergency vehicle into the world’s fastest police HUMMER represented a special challenge and one which was approached with pride. The resultant vehicle is now bound for the U.S.A and sports a supercharged 7.0-liter engine with 700 hp (515 kW). As if that’s not enough, the black and white HUMMER H2 has a brutal torque output which peaks at 904 Nm at 4,260 rpm and surely slingshots the beastie to its electronically-limited top speed of 250 km/h. That should be fast enough for the sheriff to catch just about any speedster ... though we suspect few people would wish to have this sheriff on their case.
In order to lend the flashing red-blue light bar and ear-splitting siren more credence the engine specialists installed a supercharged V8 engine with an enlarged displacement of 7.0 liters in the engine bay of the HUMMER H2.

The high-performance engine was fitted with a belt-driven supercharger with generously dimensioned intercooler. The engine mods also include special pistons, a precision-balanced crankshaft and titanium piston rods. The cylinder heads of the V8 engine were re-machined for optimized gas flow and fitted with a sport camshaft and a reinforced valvetrain. A special intake system with sport air filter and a fully stainless-steel high-performance exhaust system with high-performance manifolds and metal catalysts round out the conversion.
After reprogramming the engine electronics, the supercharged eight-cylinder engine delivers a maximum power output of 700 hp / 515 kW at 5,500 rpm and produces a peak torque of 904 Nm at 4,260 rpm. Power is transferred to all four wheels via a modified four-speed automatic transmission. Despite a curb weight of 3.1 tons the police HUMMER H2 7.0 Kompressor delivers sports car performance: The sprint from 0 – 100 km/h takes just 6.5 seconds, top speed is limited electronically to 250 km/h.
This level of performance necessitates numerous modifications to the suspension. Immediate eye-catchers are the one-piece forged chrome king-size 10Jx28 wheels with Kumho 325/35 R 28 tires.
In addition, the H2 suspension and brakes have been replaced with more robust units and the ride height lowered by some 105 millimeters, with much firmer damper settings. Sport sway bars reduce body roll in fast corners. The high-performance brake system with 380-millimeter perforated and vented discs and eight-piston fixed calipers on the front axle delivers enormous fade-free stopping power.
After transporting the police HUMMER H2 7.0 Kompressor back to the US the vehicle will be equipped with state-of-the-art police communication technology and will then serve as the personal emergency vehicle of the county sheriff.View gallery - 5 images
