According to reports, Audi is working on a facelift for its A6 sedan. The most noticeable difference on the updated car would be the company's LED headlights, earlier available on the larger A8 only.

The other updates on the facelifted Audi A6 would include refreshed bumpers, modified side skirts and a redesigned grille up front. On the inside, the carmaker is likely to provide an upgraded MMI infotainment system, along with the latest safety and driver assistance systems.

Audi is also readying the updated S6 performance sedan. Under the hood, the refreshed S6 will use the same 4.0-litre twin-turbo V8 motor but with an expected bump in power to around 429bhp. The carmaker claims improved fuel economy and a 0-100kph sprint time.

According to sources, the facelifted Audi S6 sedan will make its public debut at the Paris motor show this year and go on sale in international markets sometime early in 2015.
