Dynamic design, enthralling performance and exemplary efficiency – the Audi TT Coupe and the TT Roadster are now more attractive than ever. The design of the lightweight bodies made primarily of aluminum and the interior have been revised with great attention to detail, while new technologies lower the fuel consumption of the compact sports car. New to the lineup is a powerful and highly efficient four cylinder: The 2.0 TFSI develops 155 kW (211 hp), but is content with an average fuel consumption of just 6.6 liters per 100 kilometers (35.64 US mpg).
The second generation TT Coupe and the TT Roadster have made a name for themselves as design icons, similar to their predecessors. Awards such as the 2007 “World Design Car of the Year” document this status. A brawny, broad foundation, powerful shoulders and a flat roofline – the two compact sports cars have fascinatingly masculine lines. Their dynamic appearance is now even more expressive than ever.
The tubular, apparently floating reflectors of the tail lights add visual depth to the rear end of the car. The large tailpipes of the exhaust system – the 2.0 TFSI features a dual exhaust – and the larger, flat black diffuser set additional accents. A spoiler that extends at 120 km/h (74.56 mph) improves downforce.
The upgrades to the TT Coupe and the TT Roadster have added two centimeters (0.79 in) to both cars, which now measure 4,187 millimeters (13.74 ft) in length. The width of 1,842 millimeters (6.04 ft) and the height of 1,352 millimeters (4.44 ft) and 1,357 millimeters (4.45 ft) for the Coupe and Roadster, respectively, remain unchanged. The wheelbase measures 2,468 millimeters (8.10 ft). Four new metallic colors have been added to the TT color range: Scuba Blue, Oolong Gray, Volcano Red and Dakota Gray. Daytona Gray, pearl effect is also available with the S line package.
A key factor for the groundbreaking efficiency and excellent driving dynamics of the TT is the body, which features hybrid Audi Space Frame technology (ASF). Lightweight aluminum is used at the front of the car back to the B-pillar, with steel panels used at the rear. This mix enabled the development engineers to balance the axial loads perfectly and keep the total weight extremely low – prime parameters for dynamic performance.
The TT 1.8 TFSI weighs a mere 1,240 kg (2,733.73 lb), a good 100 kilograms (220.46 lbs) less than its closest competitor. The body of the Coupés weighs only 206 kilograms (454.15 lb), which breaks down to 140 kilograms (308.65 lb) of aluminum (68 percent) and 66 kilograms (145.51 lb) of steel (32 percent). The specific reinforcements in the TT Roadster – steel bulkhead, strongly ribbed sills, A-pillar and windshield frame – result in a 58 to 42 percent split of the two materials.
The ASF bodies of the TT are not only extremely lightweight, they are also very strong and low-vibration, providing the foundation for sporty and precise handling, the quiet ride and the high passive safety. A package of finely tuned retention systems protects the passengers in the event of a crash. The classic cloth top of the TT Roadster is a perfect complement to Audi’s lightweight construction principle. It contributes to a low center of gravity, fits ideally into the design line and takes up little space when folded.
Three four-cylinder engines with turbocharging and direct fuel injection are available for both the TT Coupe and the TT Roadster. The two TFSI gasoline engines and the TDI combine sporty performance with groundbreaking efficiency – their fuel consumption figures have been reduced by up to 14 percent. All three engines are coupled with a recuperation system that recovers energy during braking and coasting phases.
The front suspension features McPherson struts, with aluminum components used to keep the weight of the unsprung masses low. The power steering is direct, sensitive and thanks to its electromechanical drive, highly efficient. The trailing arms of the four-link rear suspension are relatively soft in the interest of comfort. The connections to the three transverse links per wheel, on the other hand, are rigid in order to direct lateral forces into the body with precision.
