At the 2010 New York auto show, BMW brought back the "is" edition of the 3-series with the 335is. A tuned version of the standard 335i, the 335is has more power and unique cosmetic features.
BMW attached the letter S to its 3-series cars since 1977, later adding a 5-series model. Designating sport, these models featured additions such as sport suspensions and seats. For the 2011 model year, the S returns to the 335i, designating a more powerful version of the 3-series.
