Audi are showing off their new A3 e-tron at next month’s Geneva Motor Show.
The Audi A3 e-tron petrol/electric hybrid is capable of up to 188 mpg with CO2 emissions as low as 35g/km. It combines a conventional 1.4-litre TFSI petrol engine, albeit modified with an electric motor.
The modified 1.4-litre TFSI unit outputs 150PS and 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. The two power units together generate 204PS of system power and 350PS of system torque, which equates to a 0-62mph time 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. According to the ECE standard for plug-in hybrid cars, the Audi A3 Sportback-based e-tron is capable of achieiving up to 188 mpg with CO2 emissions of 35g/km.Published 22 February 2013
