188mpg Audi A3 e-tron breaks cover

The German firm will show off its hybrid future at this year's Geneva motor show with the conceptual Audi A3 e-tron.

The plug-in hybrid will be powered by a combination of a standard 1.4 litre TFSI engine and an electric motor. A clutch links the petrol engine to a 75kw electric motor, which is integrated into a newly designed six-speed 'e-S tronic' transmission sending power to the front wheels.
