The Audi TTS: The Chassis
Audi has opted for a McPherson front suspension with lower triangular wishbones for the TTS. The suspension is largely made of aluminum, thereby reducing the unsprung masses. With a view to increasing rigidity, the subframe is bolted to the body at six points. The sensitive, high-precision power steering is driven electromechanically, a technology that improves fuel consumption by 0.2 liters per 100 km (0.716 mpg). The characteristics of the steering’s power assistance have been adapted to reflect the dynamic nature of the TTS.
The four-link rear suspension offers considerable benefits for vehicle handling, as it is capable of dealing with the longitudinal and lateral forces separately from one another. All of the links are made from high-strength grades of steel, while modified bearings emphasize the taut feel of the TTS. The coil springs and shock absorbers are fitted separately from one another, meaning that they take up little space.
The TTS comes standard with 18-inch cast aluminum wheels that sport the five-arm parallel-spoke S design and are shod with 245/40-size tires. Further wheel variants are optionally available, including a new 19-inch cast aluminum wheel designed by quattro GmbH. The exceptionally dynamic top-of-the-line TT model comes equipped with a high-performance braking system. Large disks are fitted front and rear, with the front disks being internally ventilated too. Inside the black-painted calipers, which bear the TTS emblem at the front, are the sport brake pads. Audi has devised a second, sporty level for the ESP stabilization program which enables controlled drifting.
Audi magnetic ride crisp and versatile
The TTS rolls off the production line equipped with yet another high-tech solution the Audi magnetic ride adaptive suspension system. Circulating inside the damper pistons is a special fluid containing minute magnetic particles. When an electrical voltage is applied, the oil’s flow properties change the characteristics of the suspension.
Audi magnetic ride works adaptively, meaning that it adjusts automatically to suit the prevailing conditions. The driver can select one of two suspension settings. In Normal mode, when oil viscosity is high, the TTS offers a well-balanced, comfortable ride. In the Sport setting, meaning low viscosity, the TTS harnesses all of the potential of its sports suspension which lowers the body by 10 millimeters (0.39 in.) to deliver uncompromisingly dynamic handling.
The Audi generates non-stop fun at the wheel as it speeds around corners like a go-cart with absolute crispness and precision, seemingly glued to the road. Any body roll is suppressed from the moment the vehicle starts to turn. The steering becomes more responsive and direct, and selective bracing of the wheels makes the self-steering more neutral.
