Sportec gives the 2010 Audi S4 Avant a makeover

Article by Christian Andrei, on July 21, 2009

Sportec’s move to use a sports air filter and a newly programmed engine control in a 2010 Audi S4 Avant prodded the vehicle to get over the 400 PS mark with its 333 compressor-PS. The Swiss tuner applied its techniques to push the vehicle to get a full 425 PS rather than the standard 333 PS from its three litre V6 compressor.

Revising its electronics raised its torque to its maximum. So instead of 440, the maximum has been increased to 520 Nm. This boost is significant in the driving dynamics. The standard Audi S4 is capable of accelerating from a standstill to 100 km/h in 5.6 seconds but the Sportec RS425 can do this in only 5.2 seconds.

Top speed is unchanged as it is electronically limited at 250 km/h. But Sportec made other upgrades too. The vehicle was given a special sports silencer with four end pipes as there will be two pairs on either side. These generate a sportier sound. Braking power is assured with a braking system on the front axles that has been enlarged to 380 millimetres.

Meanwhile, Sportec reduced the chassis clearance as it fitted the vehicle with a suspension kit made shorter by a progressive 25 millimetres.

Furthermore, the Sportec RS425 was given a set of 9 x 20 inch large lightweight metal rims covered by 245/30 tires. The Audi S4 also got a diffuser at the rear and a spoiler at the front. These two items are built of carbon.

Sportec RS425

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.
