Even though the Audi A4/S4 is one of the oldest designs in its class, and a redesign is just around the corner, it remains highly competitive. In fact, the A4/S4 is nearly everything a compact sports sedan should be. It has a solid, high-quality feel, and the interior is exquisite. Agile handling makes it fun to drive, and the ride, though quite firm, is supple and controlled.
The S4's supercharged 3.0-liter V6 provides a smooth, effortless and punchy thrust. The eight-speed automatic transmission is terrific. We measured 22 mpg overall with the A6 which has the same engine but in a larger body. The Quattro all-wheel-drive works seamlessly.
