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.
