Audi RS6 Avant C7 (2013-2018) Pros and Cons

Pros	Cons
Supercar performance meets estate car practicality	Not as much fun as a BMW M5
Beautifully made and spacious cabin	Hugely thirsty V8 engine
Four-wheel drive helps use the RS6's performance in wet weather	No saloon version available

Quick Summary

The Audi RS6 Avant C7 (2013-2018) is a high-performance estate car that combines supercar-level acceleration with practical family transport. The third-generation RS6 is Avant-only, powered by a 4.0-litre twin-turbo V8 engine producing 552bhp in early models, upgraded to 597bhp in the 2015 Performance variant. All models feature quattro all-wheel drive and an eight-speed automatic gearbox, delivering 0-62mph in 3.9 seconds (3.7 seconds for Performance models). The 565-litre boot rivals the largest estate cars on the market, whilst the beautifully appointed interior features leather seats, Bose sound system, and four-zone air-conditioning as standard.

Running costs are substantial, with realistic fuel economy in the low-to-mid 20s mpg despite official figures of around 29mpg. Servicing costs approximately £500 annually, whilst performance tyres and brakes are expensive replacements. The RS6 is a luxurious, velvet-wrapped sledgehammer rather than a pin-sharp sports car, offering monstrous power and impressive practicality. It's not the sharpest handling rival, but its ability to deliver supercar pace from standstill whilst accommodating the family makes it a compelling alternative to large performance SUVs.

Best for: Buyers seeking supercar performance with estate car practicality, those prioritising four-wheel-drive capability, and families wanting a high-performance vehicle without sacrificing space.

Not ideal for: Budget-conscious buyers, those seeking the sharpest handling dynamics (like a BMW M5), or drivers concerned about fuel consumption and running costs.


Comparison vs Key Rivals



The Verdict

You should buy the RS6 Avant if: You want supercar performance with estate car practicality, prioritise four-wheel-drive capability, or seek a high-performance family vehicle without sacrificing space.

Consider alternatives if: You're budget-conscious, prioritise the sharpest handling dynamics, or are concerned about fuel consumption and running costs.

Competitive Position: The Audi RS6 Avant C7 is a compelling high-performance estate car that delivers monstrous power and impressive practicality. Whilst rivals like the BMW M5 offer sharper handling and the Mercedes-AMG E63 provides more engaging dynamics, the RS6's combination of supercar acceleration, four-wheel-drive capability, and genuine family-friendly space makes it a distinctive proposition. It's a luxurious, powerful alternative to large performance SUVs, best suited to those prioritising performance and practicality over outright handling finesse. The beautifully appointed interior and excellent build quality reinforce its premium positioning.
