Audi RS6/RS7 C7 Buying Guide
Audi RS6/RS7 C7 Buyers Guide
The Audi RS6 and RS7 C7 are some of the most exciting high-performance vehicles Audi has produced. Both cars offer an exceptional balance of power, luxury, and everyday usability. However, as with any used performance car, potential buyers should be cautious and thoroughly research what to look for before making a purchase. This guide will highlight the key factors to consider when buying a used C7 Audi RS6 or RS7.

Engine and Transmission
The heart of the C7 RS6 and RS7 is their 4.0-litre twin-turbo V8 engine, which produces an impressive amount of power and torque. In the RS6, you can expect 552bhp, while the RS7 boasts 592bhp in standard form. Both models can achieve 0-60mph times in around 3.5 seconds, making them incredibly quick.
When inspecting the engine, it’s important to look for any signs of oil leaks, as turbocharged engines can be prone to this issue. Regular oil changes are crucial for these high-performance engines, so ask the seller for maintenance records. Ensure that the transmission, which is typically an eight-speed automatic, shifts smoothly with no hesitations or jerks. A rough or delayed shift could indicate a problem with the transmission.
Suspension and Handling
Both the RS6 and RS7 come with Audi’s adaptive air suspension, which allows for a smooth ride in comfort mode and a firmer, sportier feel when needed. Over time, these systems can wear out, and replacing air suspension components can be costly. Check for any warning lights on the dashboard that could indicate issues with the suspension. If possible, test the car in both comfort and sport modes to assess the suspension’s responsiveness.
Additionally, the handling of these cars is significantly influenced by their all-wheel-drive Quattro system. It’s worth checking the condition of the tyres as well, since uneven wear can be a sign of misalignment or suspension issues.

Brakes
Given the performance potential of the RS6 and RS7, the braking system is key to the driving experience. The standard brake setup is more than adequate for most driving scenarios, but some models may come equipped with optional carbon ceramic brakes, which offer even better performance and longevity. However, they are significantly more expensive to replace.
If the car you're considering has carbon ceramics, ensure they are in good condition. Check for any signs of cracks or unusual wear. Even if the car has standard brakes, ensure the discs and pads are in good condition, as worn brakes can greatly affect performance.
Exterior and Interior Condition
While performance is a major selling point for the C7 RS6 and RS7, the condition of the car’s exterior and interior shouldn’t be overlooked. Look out for any signs of accidents or poor repairs. The front of these vehicles can often show stone chips, especially on the RS6, which tends to see more aggressive driving due to its station wagon styling. Check the paint for any signs of respraying, as this could indicate past damage.
Inside, examine the quality of the leather upholstery, seats, and infotainment system. Both cars come with a range of tech options, so ensure that everything, from the multimedia system to the air conditioning, is functioning properly. Any warning lights or system malfunctions should be addressed before purchasing.
Service History and Running Costs
When purchasing any used high-performance vehicle, it’s essential to check the service history. The RS6 and RS7 require regular maintenance, and a lack of proper service records could indicate neglect. Ideally, you want to see evidence of regular servicing by Audi or a reputable specialist. Timing belt and camshaft adjustments, along with regular fluid changes, are essential to the longevity of these cars.
In terms of running costs, it’s important to remember that fuel economy is not the strong point of these cars, so be prepared for higher running costs than a typical Audi. Additionally, servicing and repairs can be more expensive, especially if using official Audi parts.
Common Issues
While the RS6 and RS7 C7 are generally reliable, there are a few common issues to watch for. Aside from the previously mentioned turbocharger oil leaks, other areas to consider include:
- Exhaust issues: The V8 engine can develop exhaust leaks, particularly in older models. Listen carefully for any unusual noises during a test drive.
- Electronics: As with many modern Audis, the RS6 and RS7 are loaded with electronic systems. Problems with the MMI (Multi Media Interface) or the digital display can sometimes arise, so ensure everything is working as it should.
Conclusion
The Audi RS6 and RS7 C7 are highly capable, fast, and practical performance cars, but buying one requires careful consideration. By paying attention to the key areas of the engine, suspension, brakes, and general condition, you can avoid potential pitfalls and enjoy these cars to their full potential. Always conduct a thorough inspection, review the car’s service history, and consider having a trusted mechanic assess the vehicle before making your final decision.
With proper care and maintenance, the C7 RS6 or RS7 can offer years of exhilarating driving and luxury.
