This latest e-tron concept uses a plug-in hybrid drivetrain to deliver fuel consumption of just 1.5l/100km and CO2 emissions of just 35g/km, according to European plug-in hybrid standards.
Specifically, the system includes a 110kW version of Audi’s 1.4 litre TFSI petrol engine, connected via clutch to a disc shaped 75kW electric motor for combined outputs of 150kW and 350Nm.
This clutch arrangement is tuned to make the most of the two power sources' relative power bands, with the electric motor doing much of the work up to 2000rpm, and the petrol motor optimised for 1750-4000rpm.
Power is then sent to the front wheels via an e-S tronic six-speed dual clutch transmission, to deliver a claimed 0-100km/h time of 7.6 seconds and top speed of 222km/h.
Each power source is capable of providing drive independently, and can hit 130km/h in pure-electric mode with a maximum range of 50km.
Audi’s press material makes no mention of the A3 e-tron’s power storage system or charge characteristics, but all is likely to be revealed at its Geneva appearance.
Despite being dubbed a concept for now, the A3 e-tron concept is likely a thinly veiled preview of an upcoming production model.
Visually, the concept remains close to the regular 2013 A3 Sportback due here before mid-year, but adds e-tron specific inserts to the S line front and rear fascias, and e-tron-specific multispoke wheels.
This is Audi’s third A3 e-tron concept to date, following the pure-electric A3 e-tron 'technical study' based on the previous generation Sportback in 2011, and the hybrid A3 e-tron sedan concept unveiled in Shanghai soon after.
Audi is likely to reveal its production plans for the model at the Geneva unveiling, so keep an eye on TMR for any updates.
