Where d all this perpetual motion stuff come from?

The "Hammerhead Eagle i-Thrust" () as featured on Topgear was basically an electric car powered by a small engine (In this case a small diesel generator) and that certainly wasn t a perpetual motion machine!

As would be my ossom Quad-Tesla-driven Yaris with its D4D powerplant idea

Powering electric motors off a normal engine would still be more efficient than that engine driving the wheels directly as you can tune the generator engine to be extremely efficient at a fixed and low RPM and let the electric motors worry about climbing up and down the RPM range (Unlike ICE s, electric motors are super efficient throughout their RPM range vs for instance my D4D which IIRC only hits peak efficiency between 2000 and 3000RPM)

@mrpj - This is one of the biggest plusses that I can give to Toyota; Unlike companies like Peugeot, Ford, Citreon, Vauxhall etc. they do recalls of faults without people having to die and VOSA ordering them to first!
