1975 BMW 3 Series

BMW is busily drumming up buzz ahead of the launch of the next-generation 3 Series. The company has released a slew of brief videos depicting the sketch work behind the vehicle's predecessors. Unfortunately, there's not much to the short clips beyond some pencil lines and a still image robbed from old PR photos, but the videos do a smart enough job underscoring the evolution of BMW design over the decades. BMW is set to pull the sheets off of the next interpretation of the company's midsized fighter this Friday, October 14 via a live webcast. For more information, feel free to check out the company's Facebook page.

Our spy photographers have already given us a pretty clear glimpse of what the vehicle will look like when it debuts, but we're still itching to hear details on future engine options. The rumormill has been kicking full force on the possibility of an ActiveHybrid version of the 3 Series as well as a turbocharged four-cylinder model. Hit the jump to check out the gaggle of videos for yourself.
