Oregon increases registration fees for electric vehicles to double and nearly triple that of gas-powered vehicles, because they do not pay gas taxes. Also increases registration fees for vehicles having an EPA rating of 40 or more miles per gallon.
OReGO is a new system that charges license fees “by the mile”. For EVs not in OReGO, the first 4 year fee is $612 versus a typical gas car paying $264. For the next years, the EV pays $306 versus $132, or nearly triple the price.
