Toyota's FT-HS hybrid closer to reality?

Built on the GS450h hybrid powertrain?

After the Chevy Volt, Toyota's FT-HS hybrid concept was my favorite hybrid at the North American International Auto Show. This potential Supra replacement is nearing reality according to the Winding Road and rumors out of Japan.

The 400 hp FT-HS will probably be built on the GS450h hybrid powertrain - possibly utilizing the next generation Hybrid Synergy Drive, and thus lithium-ion batteries.
