New Prius 1/x

[Lazarus]

You think this will ever make to the US.

The hybrid powertrain in the ultra-lightweight 1/X combines a home-rechargeable lithium-ion battery pack with a 500cc flexible-fuel engine in a system that is 1/4th of the total weight of the Prius powertrain. The result is a vehicle with the possibility of traveling more than 600 miles on a small four-gallon tank of fuel and achieving acceleration performance equivalent to that of the Prius.

Too many exotic materials to make it cost effective unfortunately.
