Sportec Audi S4 Avant
An original Audi S4 Avant produces 333ps, but it seems that this much power is not enough for the tuners from SPORTEC. That is why they boosted up the engine to 425ps and 520Nm of torque. The result is 0-100km/h for 5.2 seconds. The top speed is electronically blocked at 250km/h.
The upgrades are newly programmed engine control and the installation of a sports air filter. 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 9J 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.
