Are these photos of a work-in-progress Super GT Lexus LF-A? Based on the quality of these renderings, one would think so...
... however, these graphic illustrations are really just the work of Deviant ART member Iain Chandler, a.k.a "The IC". His fabulous ideas and designs of what the LF-A might look like as a participant in the high-profile Japanese race series are simply awesome. Much thought clearly went into the design of the wide-body panels, exhaust exit placement, tow hook, etc.
Who knows, we might just see something similar in the near future, in the flesh!
