Extreme Hybrid goes 250 miles on gallon of gas

On Thursday, the AFS Trinity Power Co., a private corporation that develops energy storage technologies, announced it has filed a patent for a plug-in hybrid capable of traveling more than 250 miles on a gallon of gasoline or ethanol. After being charged overnight on regular house current the Extreme Hybrid can travel up to 40 miles on battery power alone before switching to standard gasoline/ethanol and battery.

AFS Trinity will be partnering with Ricardo, a major automotive design and engineering company, which will develop the XH's drivetrain. A similar plug-in hybrid, the Prius Amberjac, can be found over at AutoblogGreen.
