[Mgs] wanted - now DSG 7 speed

[Hans Duinhoven]

Dan,

I think you're right.
I got the name from a basic A4 configuration and I assume Audi will not use
traditional automatic gearboxes anymore.

Cheers,

Hans

  Actually, Hans, Tiptronic is the regular Audi automatic transmission with
manual shift feature. Their version of the
  DSG was called S-Tronic. Not sure if it still is, or if they just call it
DSG now as well. But Tiptronic isn't it....

  I never studied the DSG principles, but
http://en.wikipedia.org/wiki/Direct-Shift_Gearbox gives a nice explanation.
BTW Audi calls this gearbox Tip-Tronic


  Cheers,

  > 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.

fuel *and* have minimum drag.  The computer restarting the engine and matching
revs to road speed as well as engaging the appropriate gear and clutch.
