A test drive on a used EV requires a different approach to a petrol car. There is no engine noise to listen for, no gearbox to assess but there is plenty to observe, and one check that has no petrol car equivalent at all. Here is how to do it properly.
Before you move
Note the state of charge percentage, estimated range, and odometer reading. Write them down. You will use these to calculate battery consumption at the end of the drive.
What to listen for
Without engine noise, an EV's cabin reveals sounds a petrol car would mask. Motor whine should be smooth and consistent erratic pitch or vibration suggests a drivetrain issue.
Suspension clunks over bumps are more audible. Tyre drone from uneven wear is more noticeable.
Brake noise grinding or juddering may indicate worn components or corroded discs.
What to feel for
Power delivery should be immediate and linear smooth from rest, consistent at all speeds. Hesitation, surging, or uneven delivery needs investigating.
Regenerative braking should feel smooth and progressive jerky or inconsistent regen is a fault. Steering should be direct with no pulling or vibration.
The battery consumption check
At the end of the drive, note the final state of charge and odometer. Calculate miles driven divided by percentage of charge consumed. Compare against the vehicle's expected efficiency.
A vehicle consuming significantly more charge per mile than it should may have a battery or drivetrain issue.
