Comparable vehicle-A motor vehicle which is primarily self-propelled by a combustion engine and is similar to the category type of the zero emission vehicle which is being purchased. The four categories of motor vehicles are as follows:
Comparable vehicle amount-The average manufacturer's suggested retail list price (M.S.R.P.) of a comparable vehicle.
Electric vehicle-A motor vehicle which operates solely by use of a battery or battery pack and which meets the applicable Federal motor vehicle safety standards.

Hybrid electric vehicle-An electric vehicle which allows power to be delivered to the drive wheels solely by a battery-powered electric motor but which also incorporates the use of a combustion engine to provide power to the battery and which meets the applicable Federal motor vehicle safety standards. The primary source of power for the motor is the electric battery or battery pack and not the combustion engine.
Motor vehicle-A vehicle which is self-propelled and is required to be titled or licensed for highway use.
Power unit-The batteries or battery packs which provide the power to operate a zero emission vehicle.
Premium purchase amount-The amount charged for a zero emission vehicle which is in excess of the comparable vehicle amount.
