400 PS Sportec RS425 based on Audi S4 Avant

Sported decide to offer a tuning program to the already incredible Audi S4 Avant. A newly programmed engine control and the installation of a sports air filter offers a full 425 PS instead of the standard 333 PS from the 3.0-liter V6 compressor. It can also develop 520 Nm of torque and all these enable the car to speed from 0 to 100 km/h in 5.2 seconds. The model is electronically limited to reach a top speed of 250 km/h. The new RS425 is fitted with 9 x 20-inch light weight metal rims surrounded by 245 / 30 tires.

Sportec Audi S4 Avant: The Powerful Swiss Estate Car

An Audi S4 with its 333 compressor-PS is no mean thing on its own but the Swiss tuner thinks differently and by applying specific techniques has pushed the vehicle from Ingolstadt way over the 400 PS mark.

A newly programmed engine control and the installation of a sports air filter coaxes a full 425 PS instead of the standard 333 PS from the three litre V6 compressor. The maximum torque has also been distinctly increased by improving the electronics. Instead of 440 a maximum 520 Nm can now be called upon. A plus factor that is noticeable in the driving dynamics. Whereas the standard Audi S4 needed 5,6 seconds to accelerate from zero to 100 km/h the Sportec RS425 only needs 5,2 seconds. At top speeds, though, they are equal as both vehicles are electronically blocked at 250 km/h.

However Sportec is not content with solely an upgrade. A special sports silencer with four end pipes - two pairs on either side right and left - provide a more sporty sound. A braking system on the front axles enlarged to 380 millimetres ensures improved braking power. On the other hand chassis clearance has been reduced as Sportec has fitted the Audi with a suspension kit shortened by a progressive 25 millimetres.

In addition the Sportec RS425 is fitted with 9 x 20 inch large lightweight metal rims surrounded by 245/30 tyres. The Audi S4`s new look is rounded off with a diffuser at the rear and a spoiler at the front, both of which are made of carbon.
