Starting this summer you may see them zip past you on the road, glide up to parking meters and idle at the corner stop sign. But never at the gas station. Three-year-old Amp Electric Vehicles of Blue Ash has begun taking orders for conversion cars' platforms from traditional gas to emission-free electric power. The first deliveries are expected in June 2010 � ahead of its retail competitors. Amp removes all of the combustion engine related components, then replaces them with two direct drive electric motors and a battery array. The Equinox, for example, will reach a top speed of 90 miles an hour, and will go from zero to 60 miles per hour in approximately eight seconds and travel up to 150 miles on a single charge. Amp had a 312 percent increase in employees year over year in 2009.
