Even A Sheriff Sometimes Needs German Help!
Even a sheriff can sometimes use a little help from Germany:
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 (www.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
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 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
This level of performance necessitates numerous GeigerCars.de
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.
