The diesel engines have been by far the most popular, with petrol following pretty far behind. However, the hybrid engine is likely to become more popular in the upcoming years as these models start to enter the used car market.
Audi currently offers the A6 in three variants: Sport, S Line and Black Edition. The S Line has been the most popular with its good balance of value and features, including 19-inch alloy wheels, privacy glass and a sport suspension.
You should look out for a 360° camera, a premium Bang & Olufsen sound system, a head-up display, remote parking assistant technology, front and rear heated seats, quad-zone automatic climate control and a panoramic glass sunroof.
Yes, the A6 has a huge amount of passenger room, with the capability of seating three adults in the back seat comfortably. There's also a decent-sized boot for carrying suitcases and groceries.
Yes, Audi released the plug-in hybrid 50 TFSI e with a 2.0-litre engine and an electric motor to create 294bhp. When fully charged, this hybrid can offer up to 30 miles of driving on electric only before switching to petrol/electric hybrid power.
There is an automatic transmission offered with the A6 lineup and it's the most popular gearbox among used models. There's also a manual transmission option for drivers but these are quite rare on the used market.
Yes, it's possible to find a used A6 with four-wheel drive, which is known as quattro because the transmission supplies power to all of the wheels as needed. There are also used A6 models with front-wheel drive available, which benefit from better overall fuel economy.
