Is the FT-HS a "pipe dream"

When I saw the headline Pipe Dream? on AutoWeek regarding Toyota's newest hybrid concept, I couldn't wait to read the article. What possible negative arguments could AutoWeek have about one of the most interesting concept vehicles in years, I wondered. Whether Toyota builds the FT-HS hybrid or not isn't really very relevant. It's the technology. It's the fact that the FT-HS uses carbon fiber and an advanced hybrid powertrain. It's the fact that the FT-HS can go 0-60 in 4 seconds with 4 cylinder economy car fuel efficiency. Most important, it's the fact that the FT-HS was built upon a real production platform.

Then, of course, I read the article and realized there wasn't any negativity. Then again I guess I hope the FT-HS isn't a pipe dream. Then again, however, it isn't really about the FT-HS, it's about the technology producing the FT-HS.
