AUTO CAR MANUAL

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

The Sportec RS425 Audi S4 Avant also comes with a special sports silencer with four end pipes. A braking system on the front axles enlarged to 380 millimetres. 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 Audi S4 Avant is fitted with 9 x 20 inch large lightweight metal rims surrounded by 245/30 tyres.
