Eco Factor: Zero-emission efficient vehicle powered by electricity.
Silicon Valley startup OptaMotive is building the E. Rex for the Progressive Automotive X Prize, which is being claimed to be three time more efficient that a Toyota Prius. The E. Rex has a top speed of 144mph and offers a range of about 100 miles.
With an ability to go 0-60mph in less than 5 seconds, the vehicle sports a water-cooled permanent magnet that produces 45KW continuous and 125KW peak power. The battery pack that fuels the vehicle consists of 96 lithium-iron phosphate cells that have a claimed recharge time of 2.5 hours at 220V and 20amps.
