2011 BMW 335is (photos)
BMW last used the 's' for the E36 325is, which ceased production in 1995. Revived for the 335is, the letter indicates a sport-tuned version of the 335i that along with more horsepower, gets the option of BMW's seven-speed dual-clutch transmission, an option not available in the 335i.
