i think they are emphasizing the “immediately” part. if youve ever driven a 330 ZHP auto, youll know that hitting the throttle to the max causes some momentary lag for the tranny to kick down a gear or two and go WOT for you…glad to see BMW is working on an auto tranny that works

I have a question that i hope someone can answer. This article says that …”sends a positive force pulse to the engine, which immediately increases its speed from approximately 1,400 to more than 5,000 rpm.” How does this work in current automatic transmissions? doesnt the engine rpm increase as soon as throttle input is sensed in combination with the transmission shifting into a lower gear.

Does this mean BMW will not provide a sequential box except for high end models like the M cars.
That would be a shame.

its an improvement because its most likely the fastest shifting AUTOMATIC on the market. You can’t compare it with hydraulically controlled clutch gearboxes, like ferrari’s F1, BMWs SMG and VW/Audi’s DSG

The Enzo shifts in 150 milliseconds
SMGII does it in 80 Milliseconds

DSG does it in 8 Milliseconds.

How the heck in 100 an improvement?

This transmission is not a DSG competitor, BMW is working on there DSG competitor. I am excited to see what they design in house because from what I hear the borg is pretty trick.

J, I used to have a 5-speed, and I loved it. BUT, when I got my car an A4, I decided that I would rather have an auto, simply because the stop and go traffic is starting to become unbearable in my part of the world. However, the type of car did play part of the decision. If I would have purchased the new Mk. V VW GTI, I would have been hard pressed to choose between the 6-speed and the DSG. But, since I bought a 4-door car, I got an auto instead (gets better gas mileage with the auto, too!).

Regarding the DSG, it was originally implemented and designed for the Bugatti Veyron (which is owned by VW) by BW, and then expanded to the other brands owned by VW and other car companies. It is arguably the best auto transmission ever made.

Damn Americans can’t even handle a gearbox. Learn to drive!!!

I would imagine most of the extra complexity is in all the extra sensors and the software in the control unit. Though, I’m not sure how much different the actual mechanical components would have to be from BMW’s current automatics in order to achieve those shift times.

hope this gets rid of the throttle lag in e46 non M coupes…

sounds like a lot more parts and pieces to break…. what ever happened to the KISS principle?

They just need to call Borg-Warner and get the Dualtronic transmission. That’s what VW uses and they re-name it “DSG”. And its a mechanical masterpiece.

That sounds pretty good. Not as good as VW’s DSG (its still an auto!) but thats a very quick gearbox indeed.
