Audi B9 A4

The B9 generation Audi A4, launched for the 2017 model year, marked a significant technological step forward. Built on the new MLB Evo platform, it's lighter and more technologically advanced than its predecessor, introducing features like Audi's Virtual Cockpit. The standard powertrain is a 2.0L turbocharged four-cylinder, while the performance-oriented S4 uses a 3.0L turbocharged V6 producing 349 horsepower, a notable switch from the previous supercharged engine.

While the standard A4 is a capable premium commuter, enthusiast attention centers on the S4 sedan and the A4 Allroad wagon. The S4 provides a fantastic balance of all-weather performance and daily comfort, making it a desirable single-car solution. The Allroad's rugged styling and wagon utility appeal to a dedicated niche that values practicality without sacrificing a premium experience. Its limited availability compared to the sedan helps maintain its value.

The market for the B9 A4 is broad, reflecting its journey from a new car to a mature used vehicle. Early, higher-mileage examples have become quite affordable, offering a lot of technology and refinement for the price. The market's average price of around $25,000 is centered on well-maintained, mid-range A4 quattro models. Low-mileage S4 and Allroad examples from later model years command the highest premiums.

Prices range from $10,000 for early models to $105,000 for top-spec, low-mileage variants.
