Audi has revealed a plug-in hybrid version of its best-selling car on the Chinese market. The A6 L e-tron is a long wheelbase model that has been stretched by around 10 centimetres to give extra legroom for rear seat passengers. Long wheelbase cars carry a lot of status in China.
The big news for the rest of the world is the powertrain; it's a parallel hybrid system that pairs a 211hp 2.0-litre TFSI petrol engine with an electric motor putting out up to 95hp. Designed to offer zero emissions while driving in China's emerging megacities, the Audi A6 L e-tron concept can travel up to 50 miles at a constant speed of 37mph in pure electric mode. The hybrid control module chooses the best suited operating mode with the combination of engine and electric motor offering over 300hp when called upon.
Visually the e-tron is differentiated from the standard A6 by new 21-inch alloys, a redesigned chrome grille, a bespoke rear diffuser in the bumper and a new exhaust system.
It is unlikely we will see the A6 L e-tron in the UK as Audi has stated that the long wheelbase model is China specific, but the hybrid technology - shared with the recently launched A8 Hybrid - should trickle down to future e-tron models in Europe.
