Picking up the ‘GTR’ designation, the latest model builds on the success of the original using knowledge PPI engineers have gathered over the past year from racing, wind tunnel development, and autobahn and track testing. The highlight of the package is an increased focus on optimising the power-to-weight ratio of the Audi R8, with engineers simultaneously boosting power while reducing weight.
The essential part of the motor alteration is the incorporation of a specially engineered supercharger. In addition, a ram-charged sport air filter system and a high performance exhaust system made of stainless steel have been designed and added specifically to work in conjunction with this new forced-induction system.
The end result is a car with 580hp (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 only 3.7 seconds and reach a top speed of 332km/h.
