That M3 rotor doesnt look much heavier than the 30lb Plaid rotor ?
And the M3 performance motor seems to be very similar performance spec (250kW, 470 Nm) as the Plaid also ?
This chart was flashed up in that video.....
An interesting mix of motor type, voltage ?, power and torque , ratings all for the same base vehicle. .
I suspect that the motor performance is limited by the battery ?
