This latest development is designed to give some insight into how the technology will take shape in the Audi models of the future.
A modified 1.4-litre TFSI unit, in this application featuring a peak power output of 150PS, provides the more 'conventional' input for the A3 e-tron. A clutch links this to a 75kw electric motor, which is integrated into a newly designed six-speed 'e-S tronic' transmission sending power to the front wheels. Combined, the two power units generate 204bhp of system power, good for a 0-62mph sprint of 7.6 seconds and a top speed of 138mph. Peak torque from the electric motor is instantly available from rest to around 2000 rpm, and maximum torque from the TFSI engine is on hand between 1,750 and 4,000 rpm.
The Audi A3 e-tron can run exclusively on electric power for up to 31 miles at speeds of up to 80mph, or can be powered by petrol combustion alone.
