Sporting emphasis - the running gear

All of Audi's impressive know-how in the chassis and suspension development area is to be found in the Audi TT Coupé. It makes driving this "sports car, Audi style" an experience that simply has to be sampled first hand.

Many of the basic design decisions were clearly biased in favour of authentic sports-car character: the short wheelbase that's essential for maximum agility, the wide track, the large wheels with the wide rims and tyres, the low centre of gravity and the firm spring and shock absorber settings for a high level of dynamic stability.

This was the approach which also led to just about every running-gear element being redeveloped to the necessary extent. The front axle for the 132 kW front-wheel-drive car and for the two quattro versions is of MacPherson strut pattern, with new forged lower control arms, new guide joints with larger-diameter journals, new cast steel pivot bearings and specially chosen axle geometry. The anti-roll bar is pivoted directly on the spring strut at each side.

For the TT quattro, the choice fell on a rear suspension layout with combined trailing and double lateral control arms. This is a particularly space-saving design with the springs and shock absorbers mounted separately, the latter at an angle.

True-running and equally compact in design, the rear axle for front-wheel-drive cars has torsion-crank suspension. Track, camber and toe geometry has been matched to the car's sporting character.

Both rear-axle versions include an anti-roll bar. It further increases the resistance to body roll already assured by the firm suspension settings. On the TT quattro the anti-roll bar is pivoted to the wheel hub backplate by means of a connecting linkage at each side, on front-wheel-drive cars a tubular anti-roll bar is welded into the rear axle assembly.

The Audi TT Coupé has disc brakes at front and rear. The front discs are ventilated, on the more powerful version those at the rear as well. Disc diameters of 312 mm at the front and 256 mm at the rear take the car's high performance into account. The fist-type rear brake calipers are made of aluminium. This saves weight, in particular unsprung mass at the wheels, so that oscillation is reduced and dynamic stability improved. Heat dissipation is also better when the brakes are subject to severe loads.

The 17-inch cast aluminium wheels that are standard on the 165 kW TT quattro are shod with size 225/45 ZR 17 tyres, and make a powerful visual impression. Standard equipment on the 132 kW versions are 16-inch cast aluminium wheels with size 205/55 R 16 tyres.

The Audi TT Coupé's power-assisted steering has a very direct ratio, with a characteristic well suited to a sports car, for optimum road "feel" and high steering precision at all speeds. Here too the essential response of a thoroughbred sports car has been well captured.

The very latest electronic "co-pilots" ensure optimum traction, dynamic stability and safety in varying conditions. All TTs have anti-lock braking (ABS) as standard, and also an electronic differential lock (EDL) in the front axle and electronic braking-pressure distribution (EBD). In addition, the 132 kW front-wheel-drive version has Traction Control (ASR).
