Audi's all-new A6, sporting styling cues from the A8 and the latest infotainment system, will be due here as early as the fourth quarter of the year.

Engines in the executive sedan feature new mild-hybrid technology. A belt alternator starter works together with a lithium-ion battery to enable the A6 to coast at speeds of between 54kmh and 159kmh, and to initiate its start-stop function earlier - at speeds of up to 21kmh.
