If the computer would rather be in 4th and I'd like to be in 6th, I win. It does what I say, immediately. That's manual control. Both by the linguistics definition of the word (as I pointed out so elequently above) and by the notional definition long affixed by automotive junkies such as your- and myself. This is why even though you could "control" a Tiptronic with buttons or a stick, it wasn't a manual -- it took your "suggestion" and eventually got around to going to that gear as long as it didn't really think you shouldn't be there.

I can put my house thermostat on automatic and let it do what it needs to, or I can switch it to manual and take control of the temperature -- all with the same set of buttons talking to the same logic board. I don't have to go down to the furnace room and shovel coal for it to be manual control of the temperature in my house.

And on the opposite side of the spectrum, I have a 68 Cadillac convertible with an automatic TH 400 transmission. There is not the first sign of a logic board or even of a wire going into that transmission. Nothing between me and the transmission that's not mechanical. I can shift it manually with a stick that comes out of the steering wheel -- no buttons. But this does not a manual transmission make. It is an automatic NOT because it has an electronic interface between me and it, but because it doesn't shift with precision, delivering the gear I order up immediately upon my ordering it.

Cheers!


Except for the gearbox doesn't change gear "when and how you say" with PDK. You've no control at all over the selection of the gears or the actuation of the clutch. The computer controls everything.

You have no control over how the different parts of the process are orchestrated, how smooth or jerky the change is or anything else. It's no more manual than pressing a button to turn the car on after which it does everything itself.

You have the illusion of manual control because the computer usually agrees that it's OK to change gear when you press the button. But try changing down at 7,000rpm and you'll find out exactly how manual PDK is. Yes, that's a safety feature to protect the engine. But it illustrates that it's the computer that makes the final call over whether to change gear at all, let alone how the gear change is executed.

PDK is an automatic gearbox. Why are people so scared to accept that? It's miles better than a manual in many regards. Why not embrace that?
