Since the middle word of the acronym is MANUAL, that directly
controverts your position. Enough.
Purely adspeak to convince those who can't cope with a clutch they're
'driving' a real gearbox. It's an auto pure and simple - unless you think
of any manual box that can change gear by itself. And controls the engine
speed and clutch during gearchanges.
I think we all understand that distinction.
The big deal about the SMG is it's made internally like a manual
transmission - real gears with changes made by gear-change forks, etc. It
uses hydraulic servos to essentially do the motions your shifter hand
would do with a manual. And it has an actual clutch on the flywheel. It
is as if you had a robot to move the shift lever and push the clutch pedal
for you when you don't feel like doing it yourself.
OTOH, the traditional automatic transmission design uses planetary
gears behind a fluid torque convertor.
Internally the two transmission types are completely different.
Looking at the internal components of an SMG, you might have a hard time
telling them apart from those of a traditional 5-speed from any major
manufacturer. Not so comparing SMG internals to a conventional auto trans.
I'll take an SMG over either one anyday. If the Jetta TDI was
available here with SMG I'd have one right now.
My wife's car is an '06 750li with the Steptronic automatic transmission.
My car is an '06 M5 with the SMG.
I drive them both.
There's nobody on earth that is going to convince me that the SMG is an
automatic transmission that you can shift manually. It's a manual
transmission that may be operated in a mode that allows the computer to do
the shifts for you, if desired. I think I've tried it twice since I got the
