Audi A6 facelift spy shots

A facelifted version of the Audi A6 has been spotted on test, showing minor cosmetic changes for the both saloon and Avant models. The visual changes might be subtle, but a suite of tech updates under the skin will aim to keep the A6 competitive with the BMW 5 Series and Mercedes E-Class.

The pictures show a new design of Matrix LED headlights, thought to borrow the anti-dazzle feature first seen on the facelifted 2014 A8. Individual LEDs can be switched on or off independently, giving the driver greater illumination ahead without shining main beam directly at oncoming traffic.

The main single frame grille and lower intakes have also been revised, sporting a new set of horizontal strakes similar to the Audi A3 e-tron hybrid. Updated rear light clusters and a new rear bumper with rectangular tailpipes complete the new look.

Hybrid tech will feature in the facelifted A6, too. Audi boss Rupert Stadler confirmed at the 2014 Beijing motor show that a plug-in hybrid A6 e-tron would be offered in China from 2015, with a roll-out to European markets following soon after.

The A6 e-tron is likely to use a turbocharged petrol engine in tandem with an electric motor to deliver fuel-sipping economy. While petrol hybrids suit the Chinese and North American markets, the 2.0 TDI-powered A6 Ultra will appeal to European A6 fans, thanks to its claimed potential of 62.8mpg and 114g/km of CO2 emissions.

The new Audi A6 is likely to appear in early-2015, along with a lightly revised version of the hotter S6. The revamped S6 is thought gain a 15bhp power boost for the twin-turbo 4.0-litre V8 engine, pushing output to 429bhp.
