2007 Audi RS 4: A High-Performance Avant

The 2007 Audi RS 4 represents a pinnacle of German engineering and performance within the Audi lineup. Building upon the already capable S4 platform, the RS 4 dialed everything up to eleven, offering a compelling blend of everyday usability and exhilarating track-day capability. This generation, codenamed B7, is particularly renowned for its naturally aspirated V8 engine and its aggressive yet sophisticated styling.

Highlights

• Engine & Performance: The heart of the 2007 RS 4 is its glorious 4.2-liter FSI V8 engine. This naturally aspirated powerhouse produced a healthy 420 horsepower and 317 lb-ft of torque. The engine's free-revving nature, coupled with a distinctive V8 growl, delivered an intoxicating driving experience. Power was sent to all four wheels via Audi's signature quattro all-wheel-drive system, which in the RS 4 featured a Torsen center differential for optimal traction and handling. A precise six-speed manual transmission was the sole gearbox option, further enhancing the driver's connection to the machine.
• Safety Features: Audi equipped the RS 4 with a robust suite of safety features for its time. Standard anti-lock brakes (ABS) prevented wheel lock-up during hard braking, while electronic brakeforce distribution (EBD) optimized brake pressure across all four wheels. Traction control (ASR) and stability control (ESP) helped manage wheel slip and maintain stability during challenging driving conditions. The RS 4 also featured front, side, and curtain airbags to protect occupants in the event of a collision.
• Trims: The 2007 Audi RS 4 was primarily offered in a single, highly-equipped trim level. This RS 4 Sedan designation meant that buyers received a comprehensive package of performance and luxury features as standard. Key equipment included aggressive bodywork, unique RS 4 badging, sport-tuned suspension, larger brakes, premium leather sport seats, bi-xenon headlights, and advanced climate control. The only significant variation was the availability of the RS 4 Avant (wagon), which offered the same potent performance in a more practical, albeit less common, body style.
• Other Notable Aspects:
  • Gullwing-inspired interior design: The driver-focused cockpit featured a unique "gullwing" inspired dashboard layout, emphasizing the car's sporty intent.
  • Adaptive Dampers: The RS 4 featured an adaptive suspension system that could adjust damping rates based on driving conditions, providing a good balance between ride comfort and sporty handling.
  • High-quality interior materials: Audi's reputation for interior quality was evident in the RS 4, with ample use of premium leather, aluminum accents, and soft-touch plastics.
  • Understated aggression: While visually distinct from the standard A4, the RS 4 maintained a degree of subtlety, avoiding overtly flashy styling cues.

What to Expect

Owning a 2007 Audi RS 4 is an experience that rewards enthusiasts. Expect a car that offers thrilling acceleration, precise handling, and a fantastic engine note. The quattro system provides confidence in various weather conditions, making it a viable year-round performance car. However, the RS 4 is a high-performance vehicle with a powerful V8, and this translates into specific ownership considerations.

• Maintenance: Due to its complex V8 engine and performance-oriented nature, the RS 4 can be more expensive to maintain than a standard sedan. Regular servicing, including oil changes, filter replacements, and brake fluid flushes, is crucial. Be prepared for potentially higher costs for parts and labor, especially for specialized components. Due to the V8's complexity, finding mechanics experienced with these specific RS models is recommended.
• Insurance: Insurance premiums for the 2007 RS 4 are likely to be higher than for less powerful vehicles. This is due to its performance capabilities, higher repair costs, and the fact that it's often driven enthusiastically. Obtaining quotes from several insurance providers is advisable before purchasing.
• Fuel Economy: The powerful V8 engine is not known for its fuel efficiency. Expect mileage in the low teens for city driving and perhaps the low 20s on the highway, depending on driving style.

Potential Considerations

While the 2007 Audi RS 4 is a desirable performance machine, potential buyers should be aware of certain aspects:

• Carbon Build-up: Like many direct-injection engines of this era, the RS 4's V8 can be prone to carbon build-up on the intake valves. This can lead to reduced performance and rough idling. Regular walnut blasting or chemical cleaning of the intake valves may be necessary as preventative maintenance or to address existing issues.
• PCV System: The positive crankcase ventilation (PCV) system can be a point of failure, potentially leading to oil leaks or other engine issues if not addressed.
• Suspension Components: As a performance car, suspension components can experience wear and tear over time. Replacing bushings, control arms, or shocks might be necessary depending on the vehicle's mileage and maintenance history.
• Older Technology: While advanced for its time, some of the infotainment and connectivity features will feel dated by today's standards. Bluetooth connectivity, for instance, might be basic or absent.

Overall Summary

The 2007 Audi RS 4 (B7) stands as a modern classic, offering a captivating blend of potent naturally aspirated V8 power, advanced quattro all-wheel-drive, and a practical yet sporty chassis. Its engaging driving dynamics and luxurious interior make it a compelling choice for enthusiasts seeking a performance car that can also serve as a capable daily driver. While its maintenance and running costs are higher than average, the sheer joy and engagement it provides make it a rewarding ownership experience for those who appreciate a truly well-engineered performance sedan or wagon.
