Toyota never has been a company to make frivolous concepts. They usually bring most of their concepts to production sooner or later. That being said, two recent exceptions have been the Alessandro Vota and the FT-HS. Both V6 electric hybrids, similar performance specs, but wildly different in execution and design. If the where to bring one out, at similar price points (Say $45k) which would you prefer?
