When typical car nuts see that "M" insignia on the trunk lid of a BMW, they almost unconsciously say, "Sweet!" Why? Because they know the M designation means that Bimmer is a posh and powerful beast, tweaked at the factory to a higher level of performance than the standard assembly line fare. But M isn't the only letter BMW uses to symbolize performance. It also uses "S."The S is the brand's performance level set between regular trims and those specifically modified by M GmbH, the creator of the brand's most powerful, speed-hungry machines. The line was born in the 1980s when the E21 320is hit world markets, and ever since it has served as a happy medium for buyers wanting a tad more speed for a smaller price premium. While BMW hasn't used the S designation often, it is adding an S version to the Z4 lineup for 2011, raising the little roadster's performance quotient to a level that BMW fans have wanted for years.
