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 the third-generation RS6, available exclusively as an estate car. Early models feature a 4.0-litre twin-turbo V8 producing 552bhp, whilst the 2015 Performance variant delivers 597bhp, achieving 0-62mph in just 3.7 seconds. All models utilise quattro all-wheel drive and an eight-speed automatic gearbox. The RS6 combines supercar performance with exceptional practicality, offering a 565-litre boot and spacious cabin with premium interior quality, leather seats, Bose sound system, and four-zone air-conditioning as standard.

This is a luxurious, high-performance machine rather than a sharp sports car—think velvet-wrapped sledgehammer rather than rapier. Running costs are substantial, with realistic fuel economy in the low-to-mid 20s mpg when driven spiritedly, and annual servicing around £500. Brake and tyre replacement costs are considerable, with performance tyres lasting approximately 10,000 miles under hard driving. However, strong residual values help offset ownership costs. The RS6 Avant delivers monstrous power and blistering acceleration whilst maintaining family-friendly practicality, making it a compelling alternative to large performance SUVs.

Best for: Drivers seeking supercar performance with estate car practicality, those prioritising comfort and space alongside speed, and buyers wanting four-wheel drive capability in a high-performance package.

Not ideal for: Budget-conscious buyers, those seeking the sharpest handling dynamics, drivers concerned about fuel economy, or those requiring a saloon body style.


Comparison vs Key Rivals



The Verdict

You should buy the RS6 Avant if: You want supercar performance with estate car practicality, prioritise comfort and space alongside speed, or seek four-wheel drive capability in a high-performance package.

Consider alternatives if: You are budget-conscious, seeking the sharpest handling dynamics, concerned about fuel economy, or require a saloon body style.

Competitive Position: The Audi RS6 Avant C7 is a distinctive proposition in the premium performance market, offering unmatched practicality amongst its rivals. Whilst the BMW M5 and Mercedes-AMG E63 deliver more engaging driving dynamics, the RS6's monstrous power, quattro all-wheel drive, and spacious estate body make it uniquely appealing. It's a luxurious, high-performance machine that prioritises comfort and capability over sharp handling, making it an excellent choice for those wanting supercar pace without sacrificing family-friendly versatility. Strong residual values help justify the substantial running costs.
