APS of Brackley, UK importer for the Swiss Sportec range of exclusive vehicle enhancements, announced a new performance upgrade for the 2009 onward models of the Audi S5 quattro coupé and cabriolet using the 3.0-litre supercharged, V6, TFSI powerplant.
Labelled the ‘Stage One’ upgrade, Sportec’s S5 performance enhancement package consists of a free flowing air filter element and a carefully developed ECU remap. In combination this has a dramatic effect on the power characteristics of the supercharged 2995cc Audi engine, with peak power increasing from 328 bhp at 6000 rpm to 425 bhp at 6640 rpm, a significant gain of 97 bhp.
Similarly, Sportec’s Stage One upgrade delivers a prodigious increase in torque output on the Audi S5, producing a maximum of 520 Nm (379 lb.ft) at 4250 rpm, compared to peak figure of 440 Nm (325 lb.ft) from the factory.
Careful development by Sportec’s technicians ensures that 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. However, when exercised to the full, it reduces the 0-62 mph (100 kmh) by 0.5 seconds to 4.6 seconds, while top speed is limited at 155 mph for safety reasons.
