Did you happen to buy the Audi S3 Sedan and are now looking to get rid of it for the recently unveiled RS3 Sedan?

You might want to hold on posting that ad, because ABT Sportsline has come to the rescue and will make you ride even more powerful than the RS, with an ECU tune and a new exhaust system, applied to the 2.0-liter four-banger.

With the work completed, the Audi S3 Sedan is now capable of pushing out 400 PS (394 HP) and 500 Nm (369 lb-ft) of torque, which means that the horsepower equals that of the new RS3 Sedan, while torque is up by 20 Nm (15 lb-ft). We don’t know how the extra oomph affects the 0 to 100 km/ (62 mph) acceleration, but the real RS3 needs just 4.1 seconds to complete it.

ABT also offers a slightly detuned version of the same engine, which brings the total output to 370 PS (365 HP) and 480 Nm (354 lb-ft) of torque.

Additionally, the car can be had with front and rear antiroll bars, fender inserts, entrance light, and several rim patterns, which range from 18- to 20-inch in size, wrapped in either Dunlop or Continental high-performance rubber.
