On the styling front, the models can be equipped with a rear spoiler, a sports exhaust system and 19- or 20-inch light alloy wheels. The company also offers high-performance brakes and sport springs that reduce the ride height by 30mm.
For added performance, the TT-RS can be equipped with an ABT turbocharger, an air-to-air intercooler and an optimized ECU. The modifications enable the turbocharged 2.5-liter five-cylinder engine to produce up to 470 HP (346 kW) and 630 Nm (464 lb-ft) of torque - an increase of 130 HP (95 kW) and 180 Nm (132 lb-ft). This enables the model to accelerate from 0-100 km/h in 3.9 seconds and hit a top speed of 285 km/h (177 mph).
The TT-RS Plus tuning package is less extensive so the modifications only enable the engine to produce 440 HP (324 kW) which is an increase of 80 HP (58 kW).
