A tuning program that will make you forget about the 4.2-liter V-8.
In a search for improved efficiency, Audi has replaced the famed 4.2-liter V-8 found in the S5 with a new 3.0-liter supercharged V-6 (dubbed the 3.0T) that achieves better fuel mileage and has a broader power curve. While the power output is slightly down compared to the V-8, the performance is strikingly similar. But, for those that want the added performance without having to shell out the extra money for the RS5, APS Sportec has introduced a new “Stage One” program for the supercharged V-6.
With the “Stage One” upgrade, customers receive a drastic increase in power and performance through modest upgrades. For “Stage One” APS Sportec installs an air filter with increased air flow over the stock unit, and an ECU remap. These two modifications result in a staggering 97-bhp increase, bringing horsepower output from 328 at 6,000 RPM to 425 at 6,640 RPM. The engine’s torque is also significantly increased, going from 325 lb-ft. to a strong 379 lb-ft. with 80 percent of torque available from 2,750 to 6,250 RPM. The increased power propels the S5 to 62 mph 0.5 seconds faster than stock, reaching the mark in just 4.6 seconds. For safety reasons, the top speed is still limited to 155 mph.
The “Stage One” performance upgrade for the supercharged 3.0-liter V-6 offers improved drivability and in-gear acceleration. The upgrade will be available on both the S5 Coupe and Cabriolet models. The 425-bhp upgrade will be available for £ 1,950.00 (+/- 3,000 USD) including VAT from APS Sportec – not bad for an extra 97 bhp!
