The Boxster is already in its fifteenth year of production. The base model is powered by a 2.9L flat-6 mid-engine that delivers 255 hp. The S, Spyder and Black Edition versions use a 3.4L flat-6 that produces 310 hp in the case of the S and 320 hp for the others. All are paired with either a 6-speed manual transmission or a 7-speed automatic.
