The latest project from APS of Brackley, UK importer for the Swiss Sportec is a new performance upgrade Audi S5 quattro coupé and cabriolet, 2009MY and above, that are powered by the 3.0-litre supercharged V6 TFSI engine. They call it the ‘Stage One’ upgrade, even though there’s only one plan and there’s no stage two! What’s really important is that the package adds 97 bhp to the output of S5’s V6.

So instead of 328 bhp at 6000 rpm standard you get 425 bhp at 6640 rpm, while the stock car’s 440 Nm (325 lb.ft) is now upgraded to 520 Nm (379 lb.ft) at 4250 rpm as well. They say it considerably enhances the in-gear and fast cruising performance of the car, in keeping with its luxury GT credentials, but don’t expect much as the acceleration time from 0 to 60 mph is reduced by 0.5 seconds to 4.6 seconds, and the top speed is still limited to 155 mph.

Suitable for coupé and cabriolet models of the 3.0-litre TFSI supercharged Audi S5, the Sportec Stage One upgrade is available now from APS Sportec priced at £1950.00 fitted including VAT.
