That's true. Overrevving on a downshift can't really be stopped until we go with DCTs. I drove an Audi with one of those a few weeks ago and it was sweet. The computer would only let you downshift when it thought it was appropriate but the programming was done very well for performance applications. Driving a DCT car will make you think you're Schumacher.

 

Maybe it will make you think you are Alanso. The "Ren-no" has been getting it DONE at the starts this year. A year or two ago there was talk of twin or double clutches in F1 which may be DCT.

GM's has a demo truck with a 6-speed DCT.

GM DCT

The THM 400 was/is a clutch-on-clutch 3-speed single shaft automatic, I believe. My guess is that GM will go with 6-speed auto in trucks with clutch-on-clutch, which might be DCT. They showed this in 2002, so 2006 models would be my optimistic guess for production. Note that the diagram in the link is a transaxle. Hmmm, maybe C6 ZX model? It would be a good moderately low production trial for a new powertrain bit. GM has been known to do that in the past.

 

The sad truth is if GM doesn't move these concepts into production they'll be also rans in the competition. VW & Audi already have DCTs in production in cars that aren't very high priced for their market. Chrysler has now launched MDS on the 5.7L Hemi and is getting very favorable reviews. I just don't understand why GM takes so long sometimes to get things to market.

Wouldn't a Solstice with a DCT be a great novelty? It would finally give GM something to go after and beat the Miata with.
