2009 Audi S4

When Audi released its latest-generation S4 in 2004, it broke new ground by stuffing a 4.2-liter V8 under the S4's relatively compact hood. This, along with a sport-tuned suspension, bigger wheels and more powerful brakes, allowed the S4 to take on any of its high-performance German competitors. But times have changed. No longer is 340 horsepower a jaw-dropping spec in this segment, and nonperformance versions of rival cars now match (or beat) the S4's specs.

For the 2009 Audi S4, only the convertible version remains as a carryover from last year. The sedan and wagon have been dropped, as Audi is presumably readying new versions. A fully redesigned A4 sedan appeared this year, and it will serve as the template for the new S4 when it debuts. As for this year's S4 convertible, it maintains its good looks and excellent interior quality, two of the model's best selling points.

Because other brands have considerably upped the ante on their high-performance models, the S4 convertible no longer directly competes with the likes of the BMW M3. The Audi now sits, price- and power-wise, between the 300-hp BMW 335i convertible and the 382-hp Mercedes-Benz CLK550. From this vantage point, the 2009 Audi S4 remains a solid choice for those looking for extra oomph in their small luxury convertible.
