Speculation of Toyota developing a drop-top version of its GT86/FR-S have been buzzing since the development concept hit the scene a few years ago. The drumbeat of this rumor has only gotten louder as the months have passed by. We hear that all the engineering due diligence has been done and a production-ready proposal is awaiting the final thumbs up from bigwigs in Japan. If approved, the convertible FR-S will definitely come to the U.S. We are not sure what effect the Cartel Speedster (pictured), which served as the official Grand Marshal vehicle at the Long Beach Grand Prix, had on the advancement of the project, but it is definitely food for thought.
