Sportec Audi S5 APS tuned to 317kW

Sportec, renowned German car tuner based in Switzerland - notably accustomed to tuning Porsche 911s to epic proportions - has now taken a spanner or two to the latest Audi S5 and found an extra 72kW inside the new 3.0-litre supercharged V6. Enhancements made to the engine control unit give the engine completely new mapping which includes an increase in supercharger boost pressure.

The factory air intake is also revised and a new, breath-easy air filter is put in place. All in all, an extra 72kW is a fair whack in the back but what's more important is the widened torque band. Over 80 percent of the car's torque is said to be available from 2750rpm to 6250rpm. The torque figure is also raised from 440Nm to 520Nm over the factory Audi specification.

On the outside you can also get traditional Sportec wheels to top it off. Called the Stage One tune, it's available for £1950 (AU $3370).
