By means of a software update and a sports exhaust system the performance of the V8 biturbo engine was increased by around 62 Ps and 90 Newton metres. To help the 470 horsepower get straight to work an original KICHERER PowerConverter (with an E certificate of conformity) was mounted in the vehicle. The accelerator pedal thus reacts almost immediately to the driver's commands. Both ear and eye can delight in many ways in a beautiful exhaust system at the rear of the vehicle. On the one hand even the ex-works end pipes are convincing with a modern, almost rectangular design and on the other hand the KICHERER sports exhaust system behind it produces a sportily exciting but still discrete V8 sound.
