Source > Dry Clutch DCTs Are on Their Way Out, says Getrag CTO | DrivelineNEWS.com

Why did you go for a wet clutch design when dry clutch is supposed to be cheaper and more fuel efficient?
That’s a very good question and we have spent a lot of time discussing it. At the end of the day, we have to have an effective product portfolio in terms of cost. With a dry clutch you cannot cover everything from 100 Nm to 500; in any case, if you want to be very sporty and have very high performance, you have to have a wet clutch. And at the opposite end of the scale, with very small engines we are beginning to recognize that many of them are coupled with quite heavy vehicles and that the thermal constraints on these small vehicles are sometimes greater than on a C or D-segment car.

Does this mean dry clutch DCTs are finished?
I cannot speak for our competitors, but our new generation of DCTs at Getrag will be 100 percent wet clutch. However, our current [dry clutch] 6DCT250 is one of the very best for fuel efficiency and it will stay on the market for another six to eight years.



***I also checked in Gertrag website and their latest transmission is a wet clutch. Here's a comparison between the new transmission with wet clutch vs. the old one with dry clutch used in Ford Fiesta and Focus.
