Well Paul,
All these "green" features of my new car have to be accredited by the Dutch
authoroties, so I assume it all is well approved. This gearbox gets into a
"free" coasting state whenever the speed is over 20 Km/h or higher and the
throttle pedal is fully released.
But whenever I apply the brakepedal, the DG box immediately engages the
right gearnumber for the current speed. It all works very well.
Whenever you know how the gearbox behaves, you can anticipate to its
behaviour.
F.I. this afternoon I approached traffic lights, which went red and I still
had to drive quite a distance.
So I released the throttle pedal and the car slowed down at a very easy
pace.
I have the feeling this behaviour truly saves fuel.
I know the fact of fully shutting down fuel injection when coasting with
gears engaged.
My previous car just did that (I could see the fuel economy meter go up
faster than normal when doing this.
However, I cannot changed the behaviour of my DSG gearbox at this spot.
And I must say coasting the DSG mode I do now gives a very much longer
remaining distance to drive, than I did with my previous car. Point is, one
had to have enough space upfront knowing the traffic lights are not getting
green, because then you miss the possibility to pass the green lights.
Secondly the cars behind me may become annoyed by my snail behaviour.....
The DSG gearbox is fully automatic, so I cannot force the box to get into
the 7th gear.
In fact the gear switching program is designed sucht, that it changes gears
at very low revs - everytime I'm very surprised how easy the engine still
pulls well at 1,300 RPM in highest gear (7) up onto a bridge!
Still I'm very happy with this automatic gearbox, when I compare it with a
traditional automatic gearbox.
I have drive an Audi A6 automatic 5-speed for almost 200,000 miles and that
box behaved like a truck.
I do like to USA car automatic gearboxes better - my wife drives a Daewoo
Lanos (GM gearbox), which works great, my collegue Bam drives a Chrysler
300C V8 SRT, which also has a nice gearbox and before the Audi I drove a
Chrysler Voyager automatic, which also had a nice gearchange.
But when you once have experienced a DSG, you never want to go back to a
traditional one....
Cheers,
Hans
71 BGT well asleep in wintertime - lots of snow and slippery & salty roads
are no good for a seventies car...
