The Gen 1 Leaf motor and inverter gives a maximum torque of 254Nm from 0 to 3000 RPM. The torque then drops off as motor speed increases to a maximum of 10500 RPM.In all seriousness, have you any thoughts on how the increased power/torque will affect things like the IRD, VCU, diff and the various UJs?
It's most efficient at around 5000 RPM, when it'll achieve 95% efficiency, at 150Nm torque output.
The Leaf motor never makes the same torque or power as the TD4 (260Nm), so the drive line components shouldn't be effected at all.
The way electric makes the torque and when is different to an ICE, as electric doesn't need RPM to make torque, so can supply maximum torque from 0 RPM, which of course an engine can't achieve at all.
The other advantage to electric is the motor can spin at twice the speed of a flat out TD4, so lower gearing can be used gain back some torque, and still give good high vehicle speeds.
I'm looking forward to seeing it working in the real world.
