APS Sportec Boosts Audi S5 to 425 BHP

The British tuners at APS, importers of the Swiss based Sportec range of vehicle performance enhancements, announced the launch of a new performance upgrade for the 2009 onward models of the Audi S5 quattro coupé and cabriolet that are fitted with the 3.0-litre supercharged V6 TFSI powerplant.

Dubbed Stage One, the upgrade package consists of a free flowing air filter element and an ECU remap, which have contributed to a rise in power from 328 bhp at 6000 rpm to 425 bhp at 6640 rpm, a gain of 97 bhp.

The maximum torque output on the Audi S5 has also been increased thanks to the Stage One upgrade, now producing a maximum of 520 Nm (379 lb.ft) at 4250 rpm, compared to a peak figure of 440 Nm (325 lb.ft) from the factory.

According to APS Sportec, over 80% of the maximum torque output is available from 2750 to 6250 rpm, which “both perfectly suits the characteristics of the car’s 7-speed S-Tronic transmission and highlights the user-friendliness of the conversion.”

“The additional power and torque output realised by the Sportec Stage One upgraded Audi S5 considerably enhances the in-gear and fast cruising performance of the car, in keeping with its luxury GT credentials,” a company statement reads.

Performance wise, the 0-62 mph (100 km/h) time is reduced by 0.5 seconds to 4.6 seconds, while top speed is limited at 155 mph (250 km/h) for safety reasons.

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 GBP1950.
