Audi TT RS presented at the 2011 Chicago Auto Show before sales announcement

Article by Christian Andrei, on February 10, 2011

It was eagerly anticipated for Audi to reveal the arrival date of the most powerful version of its small coupe but already, the TT-RS has been showcased at the 2011 Chicago Auto Show. AutoGuide said that Audi Canada expects to pull a similar move this month at the Canadian International Auto Show before the sales start expected this year.

But then, the coupe is set to reach the U.S. in limited numbers. Audi chose to do this after its Facebook petition page gathered in excess of 11,500 signatures after only a month.

There are high hopes for the TT-RS as it isn’t just an upgraded model in Audi’s diversified lineup. The TTS came from the Audi AG Sport division but the RS model was developed by Quattro GmbH, the team who created the R8, RS4 and RS6.

It should also be noted that what makes it stand out isn’t from the badges and chrome trim, but what’s powering it. The iron block/aluminum head powerplant, which displaces 2.5-liters, features direct-injection and turbocharging to deliver 340hp.

European buyers have a choice between a six-speed manual box and an S-Tronic double-clutch gearbox. Audi's Quattro system sends power to all four wheels with the use of a specially-modified Haldex multi-plate clutch.

The official figures for the European model indicate that the model can accelerate from zero to 62 mph (100 km/h) in 4.6 seconds and achieve an electronically limited top speed of 155 mph or 250 km/h.

The quattro permanent all-wheel drive comes standard in the Audi TT RS. Its heart is at the rear axle, where the hydraulic multi-plate clutch is mounted. Depending on the situation, the electronically controlled clutch distributes most of the torque input from the front to the rear wheels.

In a matter of milliseconds, a powerful electrical pump together with an accumulator press the clutch plates together by means of hydraulic pressure. The compact rear-axle differential and constant velocity joint in front of the propeller shaft are heavy-duty components that have been added to the quattro powertrain.

The quattro drivetrain allows the Audi TT RS to have excellent traction, outstanding stability and fascinating dynamics. Doing some laps along the racetrack and driving on winding country roads let the superior handling shine.

Accurate and responsive steering, the instantaneous chassis reactions, the grip while leaving a curve, the neutral stance at the cornering boundary and the thrilling power of the engine show that each mile in an Audi TT RS displays the pure essence of sportiness.

TT chassis builds on the revolutionary base of the Audi TT design. Its four-link suspension plays a very important part since it manages longitudinal and lateral forces individually. The electromechanical power steering is very efficient and adjusts to the speed of the vehicle.

The body is made of aluminum in the front and steel sheet at the rear, a ground-breaking mix of materials resulting in outstanding crash safety, well-balanced load distribution among axles and excellent rigidity, which lays the cornerstone for the precise handling of the Audi TT RS.

The standard sport chassis lowers the body height by 10 mm or 0.39 and features shock absorbers and tightly tuned springs. The Audi magnetic ride adaptive damping system, which comes as an option, lets the driver select any of two modes for shock absorbers by pressing the Sport button.

Dynamic mode makes it possible for Audi TT RS to ride smoothly. Comfort mode gives maximum comfort, which is best for long trips. The sportiest TT model prides itself on 18-inch wheels with 245/45 tires. They are matched with highly ventilated disc brakes with a front diameter of 370 mm or 14.57 inches and rear diameter of 310 mm or 12.20 inches.

For the heat to quickly disperse, the friction rings in the front are perforated then connected by hollow pins to the aluminum brake disc covers, surrounded by black, aluminum four-piston brake calipers with RS logos.
