APS Sportec Builds 425HP Audi S5

Last time we checked (as in a few minutes ago on the UK, US and German sites), the S5 Coupe continues to use Audi's venerable 4.2-liter V8 with 354HP, while the S5 Convertible comes with a 333HP 3.0-liter supercharged V6. Nevertheless, APS, the UK-based importer of the Swiss tuning brand Sportec, has released a performance upgrade for the S5 Coupe and Convertible with the... 3.0 TSI V6.

In any case, labeled "Stage One", the Swiss tuner's performance package for Audi's 3.0 TSI V6 consists of a free flowing air filter element and an ECU remap. While it doesn't sound like much, it manages to squeeze another 97-horsepower out of the S5's (convertible) 3.0-liter V6 unit, boosting total output from 328 bhp and 440 Nm (325 lb.ft) to an RS5-rivaling 425 bhp at 6,640 rpm and 520 Nm (379 lb.ft) at 4,250 rpm.

Sportec says the upgrade trims 0-62mph (100km/h) acceleration by 0.5 seconds to 4.6 seconds while top speed is electronically limited at 155 mph (250km/h).

The Stage One upgrade is available now in the UK from APS Sportec priced at £1,950 fitted including VAT.
