Hybrid
Audi claimed that the plug-in hybrid 50 TFSI e saloon was capable of 188mpg. In reality, expect to average 50-60mpg.
Mist again
The headlights can mist up, but they’re designed to do this, because they’re not completely sealed. Given that they’re LED, they don’t get hot.
Interior
Sit in the A6 and it’s easy to think you’re in the A8, such is the quality and hi-tech design in the cabin. Everywhere you look there are premium materials, digital screens and buttons. At first this can be daunting, but it’s pretty user-friendly.
You work the climate settings via the touchscreen, but the voice control is so good that you rarely need to press anything. Cabin space is excellent, with room for five adults, although whoever sits in the middle of the back seat will have to straddle the transmission tunnel. Boot space is impressive, with 530 litres in the saloon, and 586/1,680 litres (seats up/down) in the A6 Avant.
Prices
A6 saloons are plentiful, with buyers likely to pay just a small premium for an equivalent estate. Most A6s have a diesel engine; while petrol-powered cars have typically covered fewer miles. Plug-in hybrids are the rarest of the lot.
Running costs
All A6s come with fixed or variable maintenance schedules, with the latter the default option; services alternate between Minor and Major. An A6 can go for up to two years or 18,600 miles between checks; cars on the fixed regime need attention every 12 months or 9,600 miles. A Minor service costs £300 and the Major is £440.
