What Is Lexus Teasing Here?

Lexus sent out a very peculiar press release and picture last week teasing their planned showing for next month's Detroit Auto Show. The release only had a couple of lines saying that the newest F will debut in Detroit and has been "engineered from scratch".

Our best guess? We think it could be the brand new Lexus RC coupe getting a bit of a performance boost. Also, it could be the next-generation IS-F.
