Even a Texas sheriff can sometimes use a little help from Germany. Unusual customer requests are the norm at GeigerCars.de, Europe's leading tuner of American automobiles. But the request from a Texas sheriff to turn his new emergency vehicle into the world's fastest police Hummer, represented a special challenge even for the specialists from GeigerCars.de. After the conversion to the GeigerCars.de 7.0-liter supercharged engine with 700 bhp and a peak torque of 667 lb-ft the black and white Hummer reaches a top speed of 155 mph. That should be fast enough for the sheriff to catch just about any speeder.

In order to lend the flashing red-blue light bar and ear-splitting siren more credence the engine specialists from GeigerCars.de installed a supercharged V8 engine with an enlarged displacement of 7.0 liters in the engine bay of the Hummer H2.

The GeigerCars.de high-performance engine was fitted with a belt-driven supercharger with generously dimensioned intercooler. But that's not all. The modifications to the engine 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 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 to calibrate the GeigerCars.de power components the supercharged eight-cylinder engine delivers a maximum power output of 700 bhp at 5,500 rpm and produces a peak torque of 667 lb-ft at 4,260 rpm. Power is transferred to all four wheels via a modified four-speed automatic transmission. Despite a curb weight of 6832 lbs, the police Hummer H2 7.0 Kompressor from GeigerCars.de delivers sports car performance: The sprint from 0 - 62 mph takes just 6.5 seconds while the top speed is limited electronically to 155 mph.

This level of performance necessitates numerous GeigerCars.de modifications to the suspension. Immediate eye-catchers are the one-piece forged chrome king-size 10Jx28 wheels with Kumho 325/35 R28 tires.

In addition GeigerCars.de upgrades the police car with professional suspension and brake tuning. The sport suspension lowers the ride height of the SUV by some 4 inches, and offers firmer damper settings. Sport sway bars reduce body roll in fast corners.

The GeigerCars.de 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 GeigerCars.de 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.
