German car tuning specialists PPI Automotive have released their PPI RAZOR GTR version of the Audi R8, and it will premiere at the Top Marques Monaco 2009. A year ago, PPI introduced their R8 RAZOR edition at the Essen Motor Show which had great success. The new GTR model has all the features the R8 RAZOR did, however PPI aimed at tweaking the R8 to get extra performance gains for the GTR version. Some of the new parts they added were a re-engineered supercharger, a ram-charged intake filtering system, and a stainless steel high performance exhaust. The power numbers for this Audi R8 tops out at 580hp at 4,700rpm, and 600Nm of torque at 6,200rpm, which is exceptional for only weighing 1,580kg.

The acceleration for this R8 is amazing, in a mere 3.7 seconds it can reach 100km/h with a maximum speed of 332km/h. This is capable from extensive testing and research performed by PPI Automotive, and with their knowledge they were able to create a true sports car. With their wind tunnel testing and development, PPI was able to enhance the vehicles aerodynamics from the previous R8 RAZOR edition. A specially designed new front bumper with diffuser attached was put in place to reduce lifting forces. Larger air vents to provide cooler air to the radiators were installed, along with new side skirts giving it a sporty look. At the rear, is a special wing that comes with an adjustable Gurney-flap, with a new rear bumper and fenders to allow cooler air to enter the engine bay. Several carbon fiber parts such as a rear diffuser were installed, and it offsets the airflow between the rear wing and newly designed front bumper.

The Audi R8 RAZOR GTR sits on lightweight MAG9 Carbon Fiber forged aluminum PPI wheels weighing in at only 8.8kgs. Michelin Pilot Sport 2 tires are found on all fours and measure 255/35 ZR19 in the front and 325/25 ZR20 in the rear. A new braking system made of high performance parts was installed and it can be easily identified by its large 6-piston orange calipers. The interior received several minor upgrades such as carbon fiber throughout to save some extra weight. To name a few, carbon fiber hand-brake lever, door trims and sill protectors, radio and center console trim was all made entirely of carbon fiber.
