Auto Shanghai 2011: Audi A3 E-Tron


Audi reveals A3 concept car with hybrid powertrain

Audi chose Shanghai to reveal a new technical study: the A3 e-tron concept.

The Audi A3 e-tron concept is a four-seat notchback saloon. It measures 4.44 meters long and 1.84 meters wide, but just 1.39 meters high. The styling has all the features of the typical Audi design language with the single-frame grille is integrated into the front end, giving it a sculptured look. The frame is made of carbon fibre-reinforced polymer (CFRP), and the transversely mounted, three-dimensional aluminium louvres emphasise the showcar's width.

Designed as a plug-in hybrid, the A3 e-tron concept is propelled by two power units - a 211 hp 1.4 TFSI four-cylinder engine with turbocharging and petrol direct injection and an electric motor with an output of 27 horsepower. The system provides a combined output of 238 horsepower. Working together, the petrol engine and electric motor accelerate the notchback to 62mph in 6.8 seconds, then on to 144mph. A regulated oil pump, the intelligent 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
A compact seven-speed S tronic serves as the transmission for the compact plug-in hybrid. It comprises two transmission structures, which are operated by two clutches. Gears are alternately shifted by the two clutches for quick, smooth shifts without any perceptible interruption of traction.

The four-seat notchback saloon integrates the full breadth of the brand's technological advances from the enhanced MMI operating system to the drivetrain.
