Audi A6 (2011-2018) Pros and Cons

Pros	Cons
Stylish and comfortable interior	Not as much fun as a BMW 5 Series
Relaxing to drive, especially over long distances	S Line models have a less comfy ride
A wide choice of engines to suit different budgets and needs	Some reliability woes with the automatic gearboxes

Quick Summary

The Audi A6 (2011-2018), the fourth-generation model, is a refined and sophisticated executive saloon with excellent practicality and a first-rate interior. It offers a spacious 530-litre boot in saloon form, expandable via 60:40 split rear seats, whilst the Avant estate provides 565 litres. The car excels at covering long distances with superb insulation from wind, road, and engine noise. With generous rear passenger space and a wide range of engines available, it caters to various budgets and requirements. Standard equipment is generous, including leather upholstery, air conditioning, satellite navigation, and Bluetooth connectivity on SE models.

Driving the A6 is a smooth and suave experience, though it prioritises comfort over sportiness compared to rivals like the BMW 5 Series. SE Executive models offer superior ride quality to the firmer S Line variants. The 2.0 TDI Ultra diesel is particularly economical, achieving up to 67.3mpg when paired with the S tronic automatic gearbox. Running costs are reasonable, with fixed-price servicing packages available from Audi dealers. As a used buy, the A6 represents excellent value for those seeking a classy, comfortable executive car with generous equipment levels and strong build quality.

Best for: Buyers seeking a comfortable, stylish executive saloon for long-distance driving, those prioritising interior quality and equipment, and drivers wanting a wide choice of engines to suit their budget.

Not ideal for: Keen drivers seeking the sportiness of a BMW 5 Series, those wanting the finest handling dynamics, or buyers concerned about automatic gearbox reliability issues.

Competitive Position: The Audi A6 (2011-2018) is a strong contender in the executive saloon market, offering exceptional comfort, stylish interiors, and excellent practicality. Whilst it may not match the BMW 5 Series for driving engagement or the Mercedes-Benz E-Class for prestige, its generous standard equipment, wide engine choice, and relaxing driving experience make it an excellent value proposition.
