Rumor: 2007-2008 BMW 535i sedan due in March?

Rumors began circulating online this week suggesting BMW would bring its 306 horsepower twin-turbo I6 from the new 335i to the 5-Series for the 2008 model year. The 3.0-liter engine has been the subject of much praise since its introduction earlier this year. Most reviewers agree BMW has understated the performance capabilities of the engine -- probably in an effort to prevent the 335i coupe from stealing sales from the soon-to-be-replaced E46 M3.

A dealer source contacted by Leftlane could not confirm the report, but other BMW fans report receiving confirmation from local dealers. Reports suggest the model would become available in March. Recent spy photos indicate BMW is prepping a minor facelift for the 2008 model year. The 535 model is expected to be offered in both rear-wheel-drive and all-wheel-drive (535xi) variants.
