Audi RS6 Avant (2013-2018) Review And Buying Guide

The Audi RS6 Avant from the 2013-2018 model years redefined what a family hauler could achieve. This C7-generation powerhouse combined blistering acceleration with everyday usability, making it a favorite among enthusiasts who refuse to compromise on speed or space. Powered by a twin-turbo 4.0-liter V8, it delivered supercar-like performance in wagon form, appealing to those seeking the thrill of 0-62mph in under 4 seconds alongside room for five passengers and their gear.

Engine Power and Performance Excellence

At the heart of the RS6 Avant lies a handcrafted 4.0-liter twin-turbo V8 engine, co-developed with Bentley for refined yet ferocious output. The standard version churns out 552 bhp and 700 Nm of torque, propelling the estate to 62 mph in 3.9 seconds. Opt for the later Performance model, and power surges to 597 bhp with the same torque figure, shaving the sprint time to 3.7 seconds. Both pair with an eight-speed ZF automatic transmission and Audi’s quattro all-wheel-drive system, ensuring effortless power deployment.

Top speed is electronically limited to 155 mph as standard, but with the optional Dynamic Plus package, it extends to 174 mph or even 189 mph on the unrestricted variant. The transmission shifts smoothly in comfort mode yet snaps through gears aggressively when pushed, backed by launch control for repeatable quarter-mile runs. Fuel economy hovers around 25-30 mpg on a gentle cruise, but expect high-teens figures during spirited drives, reflecting its 2.3-tonne curb weight.

Chassis Dynamics and Ride Quality

Suspension options define the RS6’s versatility. Standard adaptive air suspension adjusts ride height and damping on the fly, lowering by up to 45 mm in Dynamic mode for better aerodynamics and handling. Many UK models featured optional steel-sprung sports suspension, which sharpened responses without sacrificing too much comfort. Quattro grip is phenomenal, with torque vectoring via a sport differential sending power to the outside rear wheel in corners for planted cornering.

Steering is precise but lacks the feedback of rivals like the BMW M5 Touring, prioritizing stability over raw involvement. Braking is a highlight: standard 19.7-inch ventilated discs suffice, but optional carbon-ceramic setups (44.3 inches front) provide fade-free stopping power essential for repeated high-speed runs. On twisty roads, the RS6 Avant devours miles with minimal body roll, though its mass dulls agility compared to lighter RS4 models.

Design and Exterior Styling

The RS6 Avant’s aggressive stance sets it apart from standard A6 estates. Wide oval exhausts, quad tailpipes, honeycomb grille, and bulging wheel arches scream performance. 20-inch alloys are standard, with 21-inch options on Performance trims adding presence. LED matrix headlights (later models) and a carbon-fiber roof reduce weight while enhancing rigidity.

Aerodynamic tweaks like active rear spoiler and underbody panels contribute to high-speed stability. Available in colors like Nardo Grey or Misano Red, it turns heads without ostentation, blending sleeper wagon vibes with RS aggression.

Interior Luxury and Technology

Step inside, and the cabin exudes Audi quality with Alcantara, leather, and carbon-fiber accents. RS-embossed sport seats offer superb bolstering and 18-way adjustability, heated and ventilated as standard. The high center console cocoons the driver, while a retractable 8-inch MMI screen handles infotainment via touchpad, rotary dial, or voice.

Bang & Olufsen audio, Bluetooth, USB, and optional HDD navigation elevate connectivity. Rear passengers enjoy climate zones, ISOFIX points, and ample legroom/headroom for adults. Visibility is excellent, aided by standard parking sensors and optional cameras.

Practicality for Daily Family Use

Despite its power, the RS6 shines as a hauler. Boot space measures 565 liters with seats up, expanding to 1,680 liters folded—ample for bikes, luggage, or DIY hauls. The electric tailgate and low load lip make it user-friendly. Five adults fit comfortably, though the central rear seat is firmer for occasional use.

Towing capacity reaches 2,500 kg braked, and all-wheel drive excels in wet/snowy conditions. It’s a true do-it-all vehicle, from school runs to track days.

Safety Ratings and Driver Aids

The A6 platform earned five Euro NCAP stars in 2011, with 91% adult protection and 83% child scores. RS6 adds stability control, hill-hold, ABS, and multiple airbags. Adaptive cruise, lane assist, and night vision were optional, alongside Parking System Plus. Brakes and quattro enhance real-world safety.

Ownership Costs and Reliability

Running costs are the Achilles’ heel. Expect £2,000+ annual tax, 37% benefit-in-kind rate, and 300-350 mile range from the 75-liter tank. Servicing hits £1,000+ yearly, with turbo and cylinder deactivation issues reported post-100,000 miles. Tyres (£250 each) and brakes wear quickly.

Used prices start at £20,000 for high-mileage examples, £40,000+ for low-mile Performance models. Check for carbon buildup, suspension bushes, and Haldex fluid. Strong residuals hold value well.

Pros and Cons at a Glance

• Pros: Explosive acceleration, vast practicality, premium interior, all-weather grip, tech-loaded
