Audi TT Roadster
Sheer sportiness, a genuine driving experience plus high power reserves – cue the new TT Roadster from Audi. The open-top sports car retains the distinctive lines of its tremendously successful predecessor, but instills them with even greater emotion, performance and dynamism. Note: Specifications listed are for European market. U.S. vehicles may have different specifications.
Audi offers a choice of two engines for its new TT Roadster. The 3.2-liter V6 power unit generates 250 hp and is coupled to the quattro drive system as standard. The 2.0 TFSI engine, which blends turbocharging with gasoline direct injection technology, delivers 200 hp to the front wheels. Both model variants can be ordered with the innovative S tronic dual-clutch gearbox as an alternative to the standard six-speed manual shift.
The chassis of the new Roadster is also built for impressive sporty performance. Its highlight is Audi magnetic ride, the optional suspension damping technology that allows drivers to choose between an uncompromisingly dynamic ride or more comfort-orientated characteristics.
To mirror the purist character of open-top motoring, the boldly styled body is crowned by a lightweight cloth hood. The TT Roadster 3.2 quattro comes as standard with a quick-action, fully automatic softtop which is available as an option for the 2.0 TFSI.
Whereas the tail end and the roof section seem to flow into one another at the rear of the TT Coupé, the soft top of the TT Roadster forms a clear contrast that gives the overall design a more geometric look. The body's lines brim with power and forward thrust. This impression is underscored by the athletic curves of the vehicle's flanks just as much as by the rising dynamic line above the sill area and the taut, muscular shoulder line. The eye-catching fuel filler cap positioned above the rear right wheel sports a classic aluminum design.
The face of the new Audi TT Roadster has an expressive feel. Wing-shaped plastic elements are embedded into the slanted, sharply tapered headlights to emphasize the three-dimensional depth of the lamp units. At the rear of the car, it is the large tailpipes and the wide diffuser which stand out. The tube-shaped reflectors seem to hover inside the tail light units. As on the Coupé, an electrically powered spoiler rises up out of the boot lid when the speed reaches 75 mph.
The TT Roadster 3.2 quattro comes as standard with an electrohydraulically powered soft top, which is available for the 2.0 TFSI as an option. This version of the soft top opens in just 12 seconds at the push of a button, and can even be operated on the move at speeds of up to 30 mph. The fully automatic hood incorporates an additional layer of soundproofing beneath the black headliner for even better acoustic and thermal insulation.
The manually operated roof is operated by means of a central catch. A mesh wind deflector that extends and retracts electrically can be ordered as an option to smooth the air stream in the interior – none of the competitor models are able to offer such a convenient solution.
To ensure that the load is distributed evenly between the axles, the steel components are located principally at the rear of the body – the bulkhead behind the passenger compartment, for example, is made from steel. This particular component, which anchors the high-strength roll-over bars with their elegant plastic covering, has a fundamental role to play in the body's overall rigidity.
Like the TT Coupé, the new Roadster is available with a choice of two transverse-mounted engines. Both generate high pulling power and impressive peak output, resulting in out-and-out sporty performance. The four-cylinder engine directs its power to the front wheels, while the V6 powers all four wheels based on the quattro principle offering dynamism and sure roadholding in equal measure. Apart from a sporty six-speed manual shift, both engines are also available in conjunction with the innovative S tronic dual-clutch gearbox for lightning-fast gear changes without any interruption in the power flow.
When fitted with the S tronic shift, the Audi TT Roadster 2.0 TFSI accelerates from standstill to 62 mph in just 6.5 seconds and reaches a top speed of 146 mph. It burns an average of just 7.8 litres of fuel for every 100 km.
The V6 unit with its capacity of 3,189 cc delivers 250 hp and a peak torque of 236 ft.-lbs. which is on tap between 2,500 and 3,000 rpm. The sonorous, ultra-compact long-stroke engine features two continuously adjustable camshafts. The TT Roadster 3.2 quattro sprints from 0 – 62 mph in 5.9 seconds with the S tronic gearbox and can, if necessary, go on to reach a governed top speed of 155 mph. It returns average fuel consumption figures of 9.5 l/100 km.
The sporty chassis has undergone complete redevelopment for the new TT Roadster. Its chief features are the complex four-link rear suspension, wide track widths, elastokinematics that have been heavily reworked, plus large wheels. The 2.0 TFSI rides on 16-inch and the 3.2 quattro on 17-inch alloy wheels. The wheels may be specified with run-flat capabilities as an option.
The construction of the four-link rear suspension, which also operates using a subframe, separates the coil springs and the shock absorbers from one another. The longitudinal links – which have a relatively soft set-up for enhanced ride comfort – absorb the propulsive and braking forces, while the rigid connection of the three transverse links for each wheel allows them to direct the lateral forces into the bodyshell with great precision.
All variants of the new Audi TT Roadster come generously equipped as standard, with the specification including the new "chorus" audio system and a driver information system, and in the 3.2 quattro, automatic air conditioning. There is a choice of two optional navigation systems, both DVD-based and featuring the exemplary MMI operating logic. Universal mobile phone preparation and the resonant Bose surround-sound system are also available.
