The Audi-exclusive tuning specialists at PPI Automotive Design GmbH have announced the plans to create 10 units of the Audi R8 RAZOR GTR-10. This car carries a V10 engine, with only the front hood, front bumper, and rear diffuser being the same aftermarket parts featured on the previous Audi R8 RAZOR GTR. Although the front fenders, front spoiler, side skirts, rear funder, rear spoiler, rear engine lid, and bumper might look similar in this project, they are all modified slightly. Under the hood, the PPI tuners refined the V10 powerplant with a roof mounted ram air-intake system, vented liftgate glass, a high performance exhaust system, and a reprogrammed ECU for the ignition map. It results in a serious power increase to 601 bhp at 7,400 rpm, and a max torque of 565 Nm at 6,400 rpm. For a comparison, the stock Audi R8 V10 produces 518 brake horsepower (bhp) from the factory.
For the exterior styling, a completely redesigned and wind tunnel tested carbon fiber wide body kit was installed on the Audi R8 RAZOR GTR-10. Compared to the originial RAZOR GTR, this new package reduces lift and adds extra cooling to the brake system and engine oil coolers. Carbon fiber has been draped across the roof pillars and doors to give an optical carbon fiber skin. This resulted in a total weight saving of 250 kg, and with the addition of the extra horsepower, the Audi R8 was able to sprint from 0 to 100 km/h in just 3.2 seconds, while reaching a top speed of 335 km/h.
The wheel and tire combo found on this R8 RAZOR includes MAG11 Forged Aluminum PPI wheels, measuring 19×9 in the front, and 20×12 in the rear. These come wrapped in Michelin Pilot Sport 2 tires, and the car tuning firm upgraded the brakes next. New 6-piston calipers with 380×36 mm brake discs were installed in the front, while the rear received smaller 356×32 mm discs. Suspension upgrades include a new set of KW coilover strut and springs kit, and PPI also offers a camber and tie rod kit with a hydraulic lift system for the front axle to increase ground clearance up to 45 mm if needed. Each of the PPI Audi R8 RAZOR GTR-10 cars manufactured will come with an aluminum plaque framed in carbon fiber showing the production number.
