New A1 Sportback Concept features an advanced hybrid system and seven-speed dual-clutch gearboxEnlarge Photo
As its name suggests, the A1 Sportback features a five-door bodystyle and a sloping rear hatch design. Other features are shared with the previous Metroproject, although the Sportback features a longer wheelbase, a new grille and unique bumpers. At 13.09ft (3.99m) long and 5.74ft (1.75m) wide, the car is still fully within the compact class, however.
Under the hood sits the same 1.4L TFSI engine as the Metroproject and is mated to a S-tronic seven-speed dual-clutch gearbox. The 150hp (110kW) petrol engine is also mated to a 27hp (20kW) electric motor, which can drive the vehicle for short distances on its own or assist the internal combustion engine during high loads. The electric motor adds an additional 110lb-ft (150Nm) of instantaneous torque and is powered by an array of lithium-ion batteries. A true plug-in hybrid which can be charged from any standard power outlet, the car also has an electric-only range of 62mi (100km) at up to 62mph (100km/h).

Audi's Drive Select system also enables the driver to choose between sporty or efficient driving modes, which alter throttle and gear-shifting response parameters to suit the driving styles associated with each. A dynamically adjustable magnetic ride suspension system co-opted from the Audi R8 and TT ensures the car is ready for whatever the driver or road can throw at it.
Eighteen-inch wheels and large four-wheel disc brakes ensure good grip and stopping power for the car's sportier moments, while the aerodynamic design and low profile enhance both efficiency and speed.
