Audi A6 review - Reliability and Safety

Top-notch safety and assistance systems should ensure maximum protection in the A6, but Audi’s warranty is only average

Given the sheer number of active and passive safety systems fitted to the Audi A6, it’s fair to say it should be one of the safer cars on the road. The company has a history of achieving five star ratings from independent safety experts at Euro NCAP, and the A6 is no different. It also earned a 93 per cent score for adult occupant protection, as well as an 85% score for child protection, 81% for pedestrian safety and 76% for its advanced safety tech.

Adaptive cruise control and active lane-keeping assistance are optional, but autonomous emergency braking is fitted as standard to the A6 – and that’s in addition to the usual plethora of airbags and electronic aids we take for granted these days.

The latest A6 is too new to have featured in our Driver Power customer satisfaction survey, but Audi itself attained a decent mid-table finish in 2019, finishing 16th out of 30 manufacturers. Owners cited well-finished cabins, quiet, strong engines and great sat-nav as plus points, but most were not impressed by running costs, while 21 per cent of Audi owners surveyed reported having experienced a fault with their car. By contrast, just 8.6 per cent of Lexus owners reported problems.

As a brand-new model, the A6’s long-term reliability is impossible to judge. For reference, Audi finished ahead of BMW and Mercedes in our 2018 Driver Power brand survey, though a higher proportion of Audi owners reported issues with their cars compared to Mercedes owners. 

Warranty 

The news here is fine, but nothing more. Audi’s three-year, 60,000-mile warranty was once average for the industry, but is now looking slightly ungenerous. BMW and Mercedes offer no mileage cap with their three-year policies, for example. You can always opt to extend your warranty to four or five years (and 75/90,000 miles respectively), at a price, when you buy your A6.

Servicing

Audi’s fixed-price servicing packages are reasonable and attractive. Pay around £470 for a three-year plan if you choose an A6 with a 2.0-litre engine, or around £600 if you choose the larger-engined 55 TFSI or 50 TDI.
