2007 Audi S4: A Detailed Overview
The 2007 Audi S4 represented the pinnacle of the B7 generation's performance and luxury sedan offerings. Building upon the already sophisticated A4 platform, the S4 was a formidable competitor in the sports sedan segment, known for its potent V8 engine, Quattro all-wheel drive, and refined German engineering.
Highlights
- Engine: The heart of the 2007 S4 was its exhilarating 4.2-liter naturally aspirated V8 engine. This powerhouse produced a robust 340 horsepower and 302 lb-ft of torque, delivering strong acceleration and a satisfyingly sonorous exhaust note. It was paired with either a precise 6-speed manual transmission or a smooth 6-speed Tiptronic automatic transmission, both channeling power to all four wheels.
- Safety Features: Audi equipped the 2007 S4 with a comprehensive suite of safety technologies as standard:
- Quattro All-Wheel Drive: This iconic system provided exceptional traction and stability in various driving conditions, enhancing both performance and safety. It continuously monitored wheel slip and could redistribute power to the wheels with the most grip, significantly improving handling and reducing the risk of skids.
- Anti-lock Braking System (ABS): ABS prevents wheel lock-up during hard braking, allowing the driver to maintain steering control.
- Electronic Stability Control (ESC): ESC helps prevent skids by automatically applying brakes to individual wheels and reducing engine power when it detects a loss of traction.
- Front, Side-Curtain, and Knee Airbags: A multi-stage airbag system provided comprehensive occupant protection in the event of a collision.
- Tire Pressure Monitoring System (TPMS): TPMS alerts the driver to underinflated tires, which can affect handling, fuel economy, and tire life.
- Trims: The 2007 Audi S4 was available in two primary body styles, each offering a distinct driving experience:
- S4 Sedan: The quintessential sports sedan, offering a blend of performance and practicality for four adults.
- S4 Avant: The sporty wagon variant, providing the same exhilarating performance as the sedan but with added cargo space and versatility.
- Other Notable Aspects:
- Sport-Tuned Suspension: The S4 featured a stiffer suspension with sport-tuned shock absorbers and springs, providing sharper handling and reduced body roll during spirited driving.
- Performance Brakes: Larger and more powerful brakes were fitted to the S4, ensuring confident stopping power commensurate with its increased performance.
- Distinctive Exterior Styling: Subtle yet aggressive styling cues, including unique front and rear bumpers, side skirts, quad exhaust tips, and S4 badging, differentiated the S4 from its A4 counterparts.
- Luxurious Interior: The cabin offered premium materials, comfortable leather sport seats with power adjustment and memory settings, a high-quality sound system, and advanced climate control.
What to Expect
Owning a 2007 Audi S4 is typically a rewarding experience for those who appreciate performance and luxury. The V8 engine provides ample power for daily driving and exhilarating weekend cruises. The Quattro system instills confidence in all weather conditions. The interior is well-appointed and generally holds up well over time, offering a comfortable and sophisticated environment.
However, it's important to note that maintenance for a performance-oriented V8 sedan can be more involved and costly than for a standard A4 or a smaller-engined competitor. Regular oil changes (often with specific synthetic oils), inspections of the drivetrain components, and potential replacement of wear items like spark plugs and ignition coils are part of the routine. Owners should be prepared for potentially higher fuel consumption compared to less powerful vehicles.
Insurance costs can also be higher due to the vehicle's performance capabilities and luxury positioning. It is highly recommended to get insurance quotes prior to purchasing.
Potential Considerations
While the 2007 S4 is a highly desirable vehicle, potential buyers should be aware of a few common considerations:
- Timing Chain Noise: A known issue on some B7 S4 models, particularly those with higher mileage, is the potential for timing chain tensioner wear, which can manifest as a rattling noise from the engine, especially on startup. This is a significant repair if it needs addressing.
- Carbon Buildup: As a naturally aspirated direct-injection engine (though not all B7 S4s were direct injection, it's a potential area to research for specific models), carbon buildup on the intake valves can occur over time, potentially affecting performance and fuel efficiency. Regular intake valve cleaning may be necessary.
- Suspension Components: Like any performance car, suspension components such as bushings, control arms, and shock absorbers can wear out and may require replacement, especially on vehicles with high mileage or that have been driven aggressively.
- Electronics: While generally reliable, some electrical gremlins can appear in older vehicles. This could range from minor issues with infotainment systems to more complex problems with sensors or modules.
Overall Summary
The 2007 Audi S4 (B7) remains a compelling choice for driving enthusiasts seeking a blend of potent V8 performance, sophisticated all-wheel-drive handling, and a luxurious, well-built interior. Its muscular engine, engaging driving dynamics, and timeless styling make it a standout in the sports sedan market of its era. While potential buyers should be prepared for the maintenance associated with a performance V8, the rewards of owning and driving this capable German sports sedan are substantial.
