To travel in an open-top roadster is to experience driving in its most authentic, original form. The TT Roadster's no-compromise design, its powerful presence and its outstanding inner values guarantee enthusiasm among everyone whose passion for driving a sports car is allied to the feeling that there should be no fixed roof over one's head when doing so.
Of course, an open car is only truly attractive if it still appeals to the eye with the soft top raised. This was the challenge facing Audi's designers as they turned their attention to the TT Roadster. In doing so, one factor was of immense help - one that is only very rarely part of the development specification for an open-top two seater: the Roadster's bodywork requirements were all taken into account when the Coupé was designed, but the Audi TT Roadster pursued its own very individual development path. This explains the many roadster-specific ideas that turn the experience of driving under open skies into pure enjoyment.
The TT Roadster opens up a new chapter in open-top car safety, beginning with the two rollover bars which, with their gleaming satin finish, are not only a striking design feature but also an integral component of the body structure and a major contribution to the Roadster's overall safety and structural rigidity.
It goes without saying that occupant protection in this car is not limited to two rollover bars alone. Crumple zones at the front and rear, high-strength side intrusion protection bars in the doors and large-volume body sill sections are other exemplary safety features. Precisely calculated reinforcement involving the use of thicker metal in the sill areas and sturdy transitions at the joints between the A and B- posts and the floor assembly give the TT Roadster its excellent torsional rigidity. Detailed vibration analysis and the appropriate local modifications to the body ensure outstandingly low vibration levels.
A sturdy windscreen frame with double anchorage inside the A-posts, additionally reinforced by a high-strength steel tube-in-tube system, two front airbags for driver and passenger and pyrotechnic seat belt tensioners combined with belt-force limiters are all part of the TT Roadster's standard equipment, as are the side airbag systems integrated into the seat backs and designed to protect the head and thorax. The car's body meets legal side impact (96/27/EC) collision requirements effortlessly, and in fact already fulfils future European frontal impact standards (96/79/EC).
Active safety in the TT Roadster is also of major importance. The standard equipment includes an electronic stability program (ESP) including electronic differential lock (EDL), electronic brake-force distribution (EBD) and traction control (ASR). This system enables the driver to remain in control of critical situations when approaching the handling limits.
Large disc brakes and the anti-lock brake system (ABS) ensure that deceleration values are outstanding. Ventilated brake discs are used at the front; the 165 kW (225 bhp) TT Roadster quattro has them at the rear, too.
Additional reserves of driving safety and dynamics are built into the uprated sports suspension with its wide track. The front axle uses the tried and tested McPherson strut principle. The rear axle on the quattro version has a trailing arm and two wishbones at each side, with separate spring and shock-absorber mountings. On front-wheel-drive cars, compact torsion-crank rear suspension with precisely tuned elasto-kinematics ensures accurate wheel location.
The turbocharged four-cylinder inline engines with a displacement of 1.8 litres and five valves per cylinder develop 132 kW (180 bhp) or, if a larger turbocharger and a second charge-air intercooler are used, 165 kW (225 bhp). Acceleration from 0 to 100 km/h is mastered by the 165 kW/225 bhp version in an amazing 6.7 seconds. The front-wheel-drive Roadster can reach a top speed of 222 km/h, the more powerful version peaks at 237 km/h.
Even more impressive than the acceleration and top speeds of both models is their vigorous pulling power. Well-chosen gear ratios in the 5-speed gearbox for the 132 kW front-wheel-drive version and 6-speed gearbox for the 165 kW TT quattro ensure supreme progress. The top-of-the-range version's maximum torque of 280 Nm is developed between 2200 and 5500 rpm. 235 Nm are available between 1950 and 5000 rpm from the 132 kW engine.
In the cockpit area, careful attention has been paid to every detail, as in the TT Coupé: the sports steering wheel, the dashboard instruments with their matt aluminium surrounds, the pedals and the stainless steel support for the left foot are all design details typical of the TT.
In addition to this there are various features designed for extra comfort and convenience inside the TT Roadster: high-grade leather seat upholstery, central locking with remote control, plus various compartments for smaller items located in the rear panel behind the seats and protected by the central locking system. The "Baseball Glove" leather which was an impressive feature of the design study is now available on request in the production Roadster as part of the optional Authentic package together with cleverly matched sound systems, adding to the character of the car.
A TT Roadster is naturally driven very often with the top down. The soft top with its large heated rear window can be opened in a single-stage process and stowed behind the seats. An electric power-operated soft-top is also available. A tonneau cover made of multi-layer synthetic material can be quickly and easily attached to conceal the soft top when open. Turbulence, something that often disturbs roadster occupants at high speeds, is reduced by an electrically retractable glass windbreak, shaped to follow the outline of the rollover bars.
