Recording Electric Vehicle Engine Numbers
Some electric vehicles (EVs) have multiple motors marked with an engine number. These motors are required to be marked with an engine number to help detect vehicle theft and rebirthing.
Because the NSW registration system only has room for one engine number, here’s what you need to do to correctly record an engine number for an EV:
- When an electric vehicle has more than one electric motor providing drive to the wheels, only record the engine number from the vehicle’s front electric motor.
- Record any other electric engine numbers in the comments field.
- If the vehicle only has one electric motor, you only need to record that motor’s number regardless of motor position.
- Do not combine multiple engine numbers in the engine number field for the same vehicle.
- For hybrid vehicles fitted with both an internal combustion engine and an electric motor, only record the number from the internal combustion engine.

This information is outlined in AIS Notice 46

As the global automotive industry transitions toward sustainable mobility, Range-Extended Electric Vehicles (REEVs) have emerged as a pivotal bridge between traditional internal combustion engines (ICE) and full battery electric vehicles (BEVs). REEVs—also known as REX (Range Extender) hybrids —blend the advantages of electric propulsion with the security of extended driving range, all while offering reduced emissions and optimized fuel efficiency.
