The original A1 e-tron was powered by a 101bhp electric motor and had a small rotary engine mounted underneath the boot floor that could kick in once the batteries had run out of charge after about 31 miles.
This latest e-tron has what Audi calls a Dual-Mode Hybrid system. There’s a 128bhp three-cylinder 1.5-litre turbo engine, two electric motors and a single speed transmission.
One of the motors functions mainly as a starter and generator but the other – which produces 114bhp – can drive the front wheels. Due to the complicated way the system works there’s a total output of 175bhp, allowing for 0-62mph in less than nine seconds.
An electric-only range of around 50 miles allows means fuel consumption stands at 282mpg and CO2 emissions are just 23g/km.
As it stands the Dual-Mode Hybrid concept is in the early stages of development but it shows exactly what Audi’s future model line-up will be capable of.
