Even a sheriff can sometimes use a little help from Germany: Unusual customer requests are the norm at GeigerCars.de, Europes leading tuner of American automobiles. But the request from a Texas sheriff to turn his new emergency vehicle into the worlds 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 hp / 515 kW and a peak torque of 904 Nm the black and white HUMMER reaches a top speed of 250 km/h. 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 thats 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 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 from GeigerCars.de 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 GeigerCars.de 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 GeigerCars.de upgrades the police car with professional suspension and brake tuning. The sport suspension lowers the ride height of the SUV by some 105 millimeters, 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. http://www.allcarnews.com/article/geiger-worlds-fastest-hummer/ personaly i would like to see this thing breaking at 250 km/h, the 0-60 is pretty impressive!
