2010 Audi S5 by Sportec..

When we discuss tuning kits provided by Sportec, we are usually talking about Porsche models. However, the British tuner actually tunes many different brands including Mercedes, BMW, Volkswagen, and even Fiat models, among others. Their latest package sees them tweaking the power on the Audi S5, both coupe quattro and cabriolet.

The package is called the "Stage One" and it uses the Audi’s 3.0-liter supercharged, V6, TFSI powerplant, a free flowing air filter element, and ECU remapping to completely revamp the car’s output. The result of this hard work is an output of 425 HP at 6640 rpm (an increase of 97 HP over the standard model) and a peak torque of 520 Nm at 4250 rpm (up from the standard 440 Nm). And as an impressive little touch, the maximum torque output is available from 2750 to 6250 rpm. With the new amount of power, the S5 makes the 0 to 60 mph sprint in to 4.6 seconds, while top speed is limited at 155 mph for safety reasons.

The Sportec Stage One upgrade is priced at £1950.00.
