The PPI Razor GTR was first introduced at the 2008 Essen Motor Show as the R8 Razor show car. After extensive testing and development on the road, track and wind tunnel the show car was transformed into a production ready model with increased power, improved handling and reduced weight over the standard Audi R8.
One of the most important engine modifications is the specially designed supercharger. This unit works in conjunction with the ram-air intake system and a high performance stainless steel sports exhaust which allows the engine to breathe more easily. These new components are precisely regulated to work with each other thanks to a new ignition control unit.
The result is that the supercharged 4.2 litre V8 develops up to 580 hp @ 7,400 rpm and 600 Nm of torque @ 6,200 rpm. This means that the PPI Razor GTR Audi R8 can reach 60 mph in just 3.7 seconds and continue on to 206 mph.
In addition to the power enhancements the PPI Razor GTR also has wind tunnel tested aerodynamics with a widebody appearance. The overall weight of the car has been significantly reduced thanks to the use of carbon fibre for the various aerodynamic features.
The front bumper of the Razor GTR has been designed to work in conjunction with a specially engineered front diffuser to increase downforce over the front axle. Larger air inlets below the headlights supply the radiators with additional fresh air, and an intake in the hood provides cooling air to the brakes. At the rear is a large spoiler to balance out the front/rear downforce.
The motor cover, made of a light high-tech polycarbonate, also features carbon-fibre ram-air inlets that replace the heavy OEM Engine cover and aid in cooling.
The exterior design of the PPI Razor GTR is further enhanced by a new widebody skin to allow the body to accommodate all the performance enhancements and wider wheels. The car utilizes specially designed lightweight wheels. At the front, 10Jx19 MAG9 wheels weighing 8.8kgs with 255/35 ZR 19 Michelin Pilot Sport 2 tires are fitted, at the rear are 12.0J x 20 MAG9 wheels with 325/25 ZR 20 Michelin Pilot Sport 2 tires.
The interior of the PPI Razor GTR is also modified and Onyx Nubuck-leather with orange coloured accents and highlights. Additionally, PPI equips the limited edition PPI Razor GTR with extensive carbon fibre trim throughout the cockpit; hand-brake lever, door sill protectors, Driver and Radio Console Surround, Door Trims, Center Console inserts, and kneepad trims, the ultra-light folding sport seats are also made of carbon fibre.
