I have a new VW Rabbit. It has a regular automatic transmission mode, a 'sports' transmission mode (in which 'gear shifts occur at higher rpm')
and then a 'Triptronic Mode'.
Triptronic was apparently invented by Porsche, and it seems to have spread to other german cars, like Mercedes, and now apparently Volkwwagen. You
move the gear selector to the side, from normal drive, and then can push it forwards or backwards to upshift or downshift respectively.
If the RPMS are approriate, the transmission computer will put you into the next gear. If downshifting one gear would exceed the rpm limit, then it
won't drop into it, or if upshifting produces too low rpms, then it won't do it either.
Supposedly, in the Porsche at least, you can 'que' down and up shifts. If you select it, but it'd produce an unsatisfactory RPM, then the computer
, until you reach an rpm that won't overrev after shifting.
It seems like the VW Triptronic doesn't do that. What it will do however is move up and down on its own so as not to max out or under-rev or
whatever. I found this out by forgetting that i was in triptronic mode and driving along from a stop while originally at 1, and ending up at 5 or 6
What I don't really understand is the point
. I mean, i get that downshifting in Triptronic allows me to use the engine to aid is slowing down
and stopping, but is that really that much of a benefit? Am I saving wear on my brakes significantly if I use that when stopping? Or is it a waste of
time? And sometimes it feels
like i am still getting that effect when i am in the regular drive mode, but according to the manual, there is no
stopping benefit when in full automatic mode.
And it seems like it just isn't smooth enough to be of much use in any sort of emergency situation, to hit the brakes AND go into triptronic and then
slowly downshift all the way to one. Or am I wrong and thats worthwhile?
, from what I understand, it used to be that an automatic transmission was inferior to a manual, in terms of power and gas efficiency. But
on the Rabbit, its saying that the full automatic is a 'fuel saver' mode, that it will switch gears at gas-effieciency favourable RPMS (or at least
implies that). Can that even be true? If so, is there any reason to muck around with the Triptronic mode really?
Any other opinions on this sort of thing? Any other comments?
Apparently Triptronic exists under other names in other brands.
