Having already rolled out the standard TT Coupe and Roadster, Audi has used the Paris Motor Show to unveil its TT Sportback concept, which wraps a powerful 2.0-liter TFSI engine and quattro all-wheel drive in a stretched, four-door coupe body.
The 2.0-liter, turbocharged engine under the TT Sportback’s bonnet channels 294 kW (400 hp) and peak torque of 450 Nm (332 ft.lb) is available between 2,400 and 6,000 rpm, with the power routed through a seven-speed “S tronic” gearbox. This will send the TT Sportback from 0-100 km/h (62 mph) in 3.9 seconds and Audi claims that, in spite of its performance, the concept will use fuel at a rate of just 7.0 L/100km (33.6 mpg).
To eke every possible bit of performance out of the engine, Audi has fitted aluminum pistons and a crankshaft that is made of high-strength forged steel, while the crankcase is cast out of high strength alloy. Boost pressure is running at 1.8 bar and the TT Sportback’s 21-inch wheels and 255/30 tires are suspended by a McPherson front suspension and four-link rear system. Brakes are 18-inch units all around.
Apart from the drivetrain, the most arresting element on the Sportback concept is the extra doors on the back of the coupe. The Sportback’s body is 29 cm (11.4 in) longer and 6 cm (2.4 in) wider that of a standard TT, with a 12 cm (4.7 in) longer wheelbase. These changes allow for an extra set of frameless doors, which give access to the two individual rear seats.
Rear seats aside, the TT’s interior is largely unchanged. The production coupe’s high-tech 12.3-inch “virtual cockpit” instruments and slick air-conditioning integration carry over, as does the car’s wing-shaped dash.
There is no word from Audi as to whether the Sportback will join the standard TT Coupe and Roadster on showroom floors.
