German tuning firm PPI Automotive Design GmbH unveiled it’s original ‘Razor’ Audi R8 at the Essen Motor Show last year but it looks like it wasn’t enough. Now, an even more aggressive version of the car has been revealed along with word that the final production version will be unveiled at the Top Marques in Monaco on April 16.

The newer model builds on the success of the original using knowledge PPI engineers have gathered over the past year from racing, wind tunnel development, and extensive track testing. The highlight of the package is a full focus on improving the power-to-weight ratio of the Audi R8, with engineers simultaneously boosting power while reducing weight.

An essential part of the motor upgrade is the incorporation of a specially engineered supercharger. In addition, a sport air filter system and a high performance exhaust system made of stainless steel have been specially designed to work in conjunction with this new forced-induction system.

The final result is a car with 427kW and 600Nm of torque. At the same time, the R8’s 1,580kg kerb weight has been reduced by more than 250kg, enabling the Razor GTR to accelerate from 0 to 100km/h in 3.7 seconds and reach a top speed of 332km/h.

In addition to the improved speed performance, the car also has a striking widebody appearance with ultra-modern, wind tunnel tested aerodynamics. All new PPI parts, including the new front bumper, diffuser, side skirts, and hood, are made from carbon-fibre.

New wheels all round are extra-wide 19in forged alloys cloaked in 325mm Michelin Pilot Sport 2 tyres in the rear and 255mm sets up front. Sitting within these is an updated brake package with six-piston calipers all around and 380mm discs up front and 356mm units in the rear. Finishing it all off is a hydraulically adjustable suspension kit developed together with KW Automotive.
