[Mgs] wanted - now DSG 7 speed

[Charley & Peggy Robinson]

The Prius will sort of freewheel with the engine shut down at speed 
below ~40 mph.  It's called "gliding" by those who know how to extract 
this behavior from the car.  It isn't really freewheeling, it's a matter 
of MG1 spinning at a speed that allows the engine to cease rotation - 
possible in a 3-way planetary gearset.

Have you read up on how the DSG gearbox(s) work?
