I understant this is a 'classical' hybrid car that allows recharging the battery from an outlet. So both the gas engine and the battery drive the wheels. This is what Vue plug-in hybrid will be like.
Volt is more than this, since there's no connection between the gas engine and the wheels. The engine only recharges the battery. So, this requires a more advanced battery that the 'classical' hybrid. The mileage also will be greater.
