German tuning firm, Manhart, has posted
teasers of its upcoming BMW i8. Though these are just photoshopped images for now, it appears that they plan to maintain the factory exterior while adding bright dashes of paints on some accent pieces, as well as aftermarket wheels and lowering the suspension.
The more important question is what, if any, performance modification plans the tuner has for the i8. That should be answered in time.
