Although BMW themselves have yet to confirm that the rumors are true, many enthusiast sites appear to have insider information indicating that BMW will indeed debut a Motorsport edition of their newest 1 Series in 2010. Expected to replace (in theory, not literally) the 335i as the link between the M3 and the 135i, and is rumored to come replete with carbon fiber inserts and some sort of BMW Performance Body Kit. Sources conflict as to what sort of engine the M1 will receive, but the options have been whittled down to either a turbocharged 4-cylinder (currently in development) or, in keeping with BMW’s Motorsports Division tradition, a naturally aspirated straight-6. Still other Bimmer fanboys anticipate (albeit slightly unrealistically) a revised version of the twin-turbo I6 currently powering the F01 7 Series to find its way under the 2010 M1’s hood, in which case output would be rated somewhere above 330-hp.

Either way, BMW has hinted that any M addition to the 1 Series lineup wouldn’t debut until the tail end of 2010 anyway, meaning that we’ll simply have to bide our time with idle gossip until Bimmer mercifully throws us a bone.
