In addition to three or four converted Prius PHEVs, two research plug-ins from Argonne National Laboratory are to be there.
One is a Saturn VUE Green Line through-the-road parallel hybrid PHEV. The other is the “G-Volt” PHEV. The G-Volt features a series plug-in hybrid drivetrain mapping to the specs of the Chevrolet Volt but applied to a Geo research platform. The G-Volt is V2G-capable.
