Audi reveals latest EV study

Audi has used the Shanghai Motor Show to reveal its latest EV tech demonstrator: the A3 e-tron concept. The four-seater sedan integrates two powerplants and lithium-ion batteries that store enough energy to propel the car on electric power alone for up to 34 miles.

Measuring 4.44 metres long, 1.84 metres wide, and 1.39 metres high, the plug-in hybrid A3 is propelled firstly by a 211PS 1.4-liter TFSI four-cylinder engine that features turbocharging and petrol direct injection. The IC unit is supported by an electric motor with an output of 27PS. The system provides a combined output of 238PS. Working together, the petrol engine and electric motor accelerate the A3 concept to 62mph in 6.8 seconds. Top speed is 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.

At the heart of the A3 e-tron concept are the lithium-ion batteries located behind the rear seats. With a charge capacity of 12kWh, they give the A3 a range of up to 34 miles on electric power alone.

The batteries are charged by the energy recovery system when the car is in motion or directly from a household power socket when it is parked. This means that in most cases, the car is entirely emission-free in city driving.

A compact seven-speed S tronic unit 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 quickly, smoothly and without any perceptible interruption of traction
