For those that find the regular TT RS models not fast enough, Audi has announced that the new and more powerful TT RS Plus editions of the Coupe and Roadster will go on sale in Britain in early May, with first delivers expected in the summer.

The Plus package represents a £3,085 premium over the standard RS with prices ranging from £48,945 for the manual Coupe to £52,265 for the dual-clutch transmission Roadster.

What you need to know about the Plus models is that Audi’s engineers have squeezed another 20hp (20PS) and 15Nm (11.06 lb-ft) of torque from the turbocharged inline-five nudging output to 355hp (360PS) and 465Nm (342.97 lb-ft), which are channeled to the quattro all-wheel-drive system through either a 6sp manual or the 7sp S tronic twin-clutch transmission.

With the S tronic, the TT RS plus Coupe reaches 62mph (100km/h) in 4.1 seconds (manual: 4.3 seconds), while the Roadster needs 4.2 seconds (manual: 4.4 seconds). In all cases, top speed is limited to 174mph (280km/h).

Audi also quotes a combined economy test figure of 33.2mpg UK for the coupe and 32.8mpg UK for the open-top model.

The most potent edition of the TT series gets a new set of 19-inch alloys (instead of the regular model’s 18-inch rims) wrapped in 255/35 rubber, a standard sports exhaust system with black tail pipes, a matt aluminium surround for the revised grille and carbon fiber mirror caps.

The Plus package also adds more cabin equipment, including satellite navigation, Bluetooth phone preparation and Audi Music Interface iPod connection, all of which are part of the normally optional Technology Package.
