A3 e-tron sedan concept to be unveiled at Shanghai image

Vw’s premium brand Audi is set to unveil the A3 e-tron concept – in Shanghai.

The four-seat notchback sedan integrates the full breadth of the brand’s technological expertise – from the enhanced MMI operating system, to the high-end infotainment system, to the drivetrain.
And with its two powerplants and lithium-ion batteries that store enough energy to propel the car on electric power alone for up to 54 km (34 miles), the plug-in hybrid also delivers high fuel efficiency.

Audi’s engineers replaced the Geneva concept model’s 408HP 2.5-liter turbocharged inline-five with a hybrid powertrain comprising of a 211HP 1.4-liter TFSI gasoline unit with turbocharging and gasoline direct injection, and an electric motor with an output of 20 kW (27HP), for a combined system output of 238HP.

Working together, the gasoline engine and electric motor accelerate the notchback to 100 km/h (62.14 mph) in 6.8 seconds, then on to 231 km/h (143.54 mph).

Audi thermal management system, a start-stop system and an energy recovery system – technologies from the brand’s modular efficiency platform – all contribute to this high efficiency.

The all-new A3 is expected to make its international production debut in the second half of 2012, in both sedan and hatch form.
