Mounted transversely, the 2.5-litre in-line five features direct injection and turbocharging.
The engine develops peak power of 250kW and torque reaches 450Nm between 1600 and 5300rpm.
The TT RS will reach 100km/h from a standing start in 4.6 seconds. Electronically governed, the Audi can top 250km/h.
In combined-cycle testing the fuel consumption figure for the TT RS is 9.2L/100km.
The engine in the TT RS drives through a six-speed manual transmission to a quattro all-wheel-drive system, featuring a Haldex-style, electronically controlled coupling, which transmits torque to the rear wheels.
A 'Sport' button fitted as standard enables faster throttle response under load and emits an engine note sportier than the default mode. Finally, the system adjusts the car's Magnetic Ride dampers to sport mode.
Balancing weight, strength and rigidity, Audi has developed the TT RS around the company's Space Frame structure (ASF) -- something shared with the other models in the TT range. Comprising aluminium up front and steel sheet behind, the TT RS's body in white weighs 206kg -- of which aluminium accounts for 140kg. Audi claims that the body, formed entirely from steel would weigh half again. The kerb mass measurement for the TT RS is 1450kg.
