Now entering its twelfth model year and third iteration, the 2009 Porsche Boxster continues to reap the benefits of Porsche's traditional evolutionary method of engineering. As Porsche's most affordable offering, the Boxster convertibles offer all the stylish good looks and "Hey, I'm somebody" attitude of rivals from Audi, BMW and Mercedes-Benz, but in a package that is 100-percent performance oriented. New engines this year increase horsepower and fuel economy, although both models still trail their Cayman siblings by about 10 horsepower each. The numerical difference may seem minor but the performance difference is remarkable.
