Ontario (CA) – A new lithium-ion battery pack for the Toyota Prius may not lower gas prices, but it promises to make trips to the gas station less frequent – a lot less frequent. Made by Hymotion and A123 Systems - the same folks that brought you the batteries in the Killacycle – this aftermarket kit converts the car into a plug-in hybrid and allows it to run on electric power for the first forty miles of a trip. As you can expect, total gas mileage goes through the roof and company executives claim drivers can easily exceed 150 miles-per-gallon in the city and 100 MPG on the highways.
