Understanding the B9 RS4 and RS5

The Audi RS4 and RS5 B9, produced from 2017 onwards, are part of Audi’s high-performance RS range. Both models share a similar platform, the MQB (Modular Transverse Matrix), but differ primarily in body style. The RS4 is an estate (Avant), while the RS5 is a coupe. Both feature Audi’s Quattro all-wheel-drive system and are powered by a 2.9-litre V6 twin-turbocharged engine, producing impressive power numbers.

While these models offer strong performance and handling, certain variations in trim levels and optional features can affect the overall driving experience and practicality.

Trim Levels and Options

The RS4 and RS5 B9 come in several trim configurations, depending on the market and model year. In general, you’ll find the following core trims available:

• Standard RS: This is the base trim that comes equipped with key performance features such as the Quattro system, sport suspension, and RS styling elements.
• RS Plus: This trim offers more advanced options, including additional comfort features like heated and ventilated seats, enhanced multimedia systems, and larger alloy wheels. The Plus trim may also come with optional carbon fibre detailing in the interior.
• RS Dynamic: Some markets offer the RS Dynamic trim, which typically includes a larger set of performance upgrades such as upgraded brakes (carbon-ceramic), dynamic steering, and a sport exhaust system for enhanced sound.
• RS Sport Package: An option on both models, this package can offer a more aggressive appearance with black styling elements, larger wheels, and even performance-focused interior details.
• Comfort and Technology Packs: These optional packs generally focus on enhancing the cabin experience, with upgrades like a premium sound system, advanced driver assistance features (such as lane-keeping assist, adaptive cruise control), and improved interior materials.

Key Features to Look Out For

• Adaptive Suspension: The RS4 and RS5 both feature adaptive suspension, allowing the driver to switch between different driving modes for more comfort or a more dynamic driving experience. Make sure the suspension system is functioning properly, as it’s vital to the car’s handling characteristics.
• RS Sport Exhaust: If you're keen on a more aggressive exhaust note, check whether the car has the optional RS Sport exhaust. This not only enhances the driving experience but is a popular choice for enthusiasts who appreciate a louder engine note. Look for signs of wear or damage to the exhaust components.
• Wheels and Tyres: Both the RS4 and RS5 offer a variety of wheel sizes and finishes. If the car you're considering has upgraded wheels, check for any signs of damage, curbing, or unusual wear. The condition of the tyres is also important as high-performance tyres tend to wear faster, and replacements can be costly.
• Interior Wear and Tear: Inside, look for signs of excessive wear, particularly on the steering wheel, seats, and infotainment system. The RS models come with high-quality materials, but frequent use can lead to wear, especially on the bolsters of the sports seats and the touch-sensitive controls.
• Brakes: Pay close attention to the condition of the brakes, particularly if the car has been fitted with the optional carbon-ceramic brakes, which are expensive to replace. These brakes offer excellent performance but can be costly to maintain if they’re nearing the end of their lifespan.
• Service History: Audi RS models require regular servicing to maintain peak performance. Ensure the car has a comprehensive service history, ideally with Audi or a reputable specialist. If the car has missed services or has a patchy history, it may be worth considering other options.

Things to Check Before You Buy

• Warranty and Recall Checks: Audi RS4 and RS5 models come with a 3-year/60,000-mile warranty, but check whether the car you're considering is still under warranty or if any recall work has been carried out. Some owners may also have opted for extended warranties.
• Accident History: Always check for any accident damage or repairs, as this could affect the vehicle’s value and safety. An independent inspection can be a good way to assess the condition of the car beyond just what’s visible.
• Mileage: High-performance cars like the RS4 and RS5 can often have higher-than-average mileage. While these cars are built to handle performance driving, excessive mileage can lead to more wear on the engine and transmission, so ensure the price reflects the condition and mileage.
• Test Drive: Finally, never buy an RS4 or RS5 without a test drive. These cars are all about driving experience, so ensure the car feels right on the road. Pay attention to the engine performance, gear shifts, suspension comfort, and any unusual noises.

Final Thoughts

The Audi RS4 and RS5 B9 are high-performance machines that deliver a great mix of practicality, luxury, and driving excitement. When buying one, it’s important to look beyond just the trim and options and carefully check the vehicle’s condition, service history, and any potential issues. By paying attention to these details, you’ll be able to find an RS4 or RS5 that offers a thrilling experience without the costly surprises down the road.
