This has been discussed in the past but we have some new members and more knowledge so let the debate begin!

I could fit the entire choice in the poll so here are the entire choices:

1) No! HSD is locked in top gear all the time....The torque to start comes from the motor(s).

2) Yes! The action of the motor in concert with the ICE acts as gear reduction/overdrive....depending on which way the motor spins.

3) What is HSD? / Don't know /Don't care / Can't decide.
