The launch of the RS 4 (B7) was a pivotal moment for Audi, underlining its commitment to pushing the boundaries of performance and innovation. It was the first RS 4 to feature a naturally aspirated V8 engine, deviating from the previous model’s turbocharged setup. This change showcased Audi’s engineering prowess and willingness to innovate. The RS 4 B7 was not just about raw power; it embodied Audi’s philosophy of precision, balance, and everyday usability, making it a versatile performance car.
For Audi, the RS 4 B7 was a statement vehicle. It demonstrated that the brand could compete head-to-head with established high-performance marques like BMW’s M division and Mercedes-Benz’s AMG line-up. The RS 4’s success reinforced Audi’s reputation as a manufacturer capable of producing cars that were not only fast and powerful but also refined and luxurious.
A rundown on the Audi RS 4 (B7)
At the heart of the Audi RS 4 (B7) lies a naturally aspirated 4.2-liter V8 engine, designated as the FSI (Fuel Stratified Injection) V8. This engine is a masterpiece of engineering, combining high-revving characteristics with substantial power and torque. The 4.2-liter V8 produces an impressive 309 kW at 7 800 rpm and 430 N.m of torque at 5 500 rpm. These figures allow the RS 4 to accelerate from 0 to 100 km/h in just 4.65 seconds (Road Test: July 2006).
The engine’s high-revving nature, coupled with its robust power output, is achieved through advanced technologies such as FSI direct fuel injection and a high compression ratio. The direct injection system, according to Audi, leads to better combustion efficiency and power delivery. Additionally, the engine features a lightweight aluminium construction, reducing overall weight and improving handling dynamics.

Complementing the potent V8 engine is a (rejoice!) six-speed manual transmission, the sole gearbox option for the RS 4 (B7). This transmission is known for its precise and engaging shift action, providing drivers with a tactile connection to the car’s performance. The manual gearbox, combined with Audi’s renowned Quattro all-wheel-drive system, ensures excellent traction and stability in various driving conditions. The Quattro system distributes power variably between the front and rear axles, optimizing grip and handling, especially in challenging weather or road conditions.
In our 2006 report on the Audi RS 4 (B7) we noted:
“So far, [Audi’s] only really made one classic. One icon. The original Audi quattro was that car. Since then, Audi has come close a few times but never quite managed to again build a car that has both incredible capability, and a soul. Audi’s tend to be too perfect, and that makes them cold… But the Audi RS 4 won’t leave you cold. It’ll do the opposite. It’ll put your pants on fire and ignite your soul. This is, in our humble opinion, probably the best road car Audi has ever made.”
Available in sedan, Avant, and Cabriolet body styles, the RS 4 catered to a diverse range of preferences, each offering unique attributes. Whether it was the practicality of the Avant, the classic appeal of the sedan, or the open-top excitement of the Cabriolet, the RS 4 (B7) provided a compelling option for enthusiasts seeking a high-performance vehicle with versatility and style.
Things to look out for when buying a used Audi RS 4 (B7)
One of the standout features of the RS 4 (B7) is its 4.2-litre V8 engine. However, while this powerplant delivers thrilling performance, it also comes with certain mechanical vulnerabilities. A common issue reported by owners is the build-up of carbon deposits on the intake valves, which can lead to a loss of power and increased fuel consumption. Regular carbon cleaning is essential to maintain optimal engine performance.
The timing chain tensioners and guides are another area of concern. Over time, these components can wear out, leading to a rattling noise on startup or even more severe engine damage if not addressed. When inspecting a used RS 4, listen carefully for any unusual noises from the engine, particularly during cold starts.
The RS 4’s Dynamic Ride Control (DRC) system, designed to reduce pitch and roll during aggressive driving, is another point of potential trouble. While the system enhances handling, it is prone to leaks and failures over time. Replacing the DRC system can be costly, so prospective buyers should check for any signs of fluid leakage around the suspension components and verify if any previous repairs or upgrades have been done.
The interior of the RS 4 is generally praised for its high-quality materials and build. However, like any vehicle of its age, it can suffer from wear and tear. The Recaro sport seats, although comfortable and supportive, may show signs of bolster wear. Additionally, the MMI (Multi Media Interface) system, which was advanced for its time, can sometimes experience glitches or failures.
South African RS 4 (B7) owners have noted the high costs of maintenance and repairs, which is typical for high-performance German cars. The limited availability of certain parts locally can further exacerbate these costs, leading some owners sourcing parts internationally. Additionally, fuel consumption is a noted downside, with the powerful V8 being notoriously thirsty. On the other hand, the RS 4 is highly praised for its exhilarating driving experience. The combination of the V8 engine, Quattro all-wheel drive, and precise steering makes it a joy to drive on both city streets and winding country roads.
