So what happened to the rumors about GM's 8 speed double-clutch? Coming in 2015?

Would have loved to see a dual clutch paddle system on the new Corvette. Hopefully it comes as an available option in later model years.

I'd love nothing more than to see one in the C7. Not holding my breath for now though. Although Ford has developed a dual clutch transmission in house (a rather crappy one as well) GM seems content to solider along with their current 6 speed slushbox and then release the anticipated 8 speed when ready. The C7 does have some packaging issues with the rearward located transmission AND serious torque numbers to deal with. Hence the truck/4X4 transmissions used in the past. But if GM and Tadge are truly dead serious about keeping a 'Vette up in the "best sports car in the world" discussion, then a DCT is mandatory in the future IMHO. Even if they put in an 8 speed auto that can hang with the current 8 speed Aisin and ZF boxes, there's just no comparison with the sheer shift speed of a dual clutch setup IMHO. Go drive an Audi S4/S5 with S-Tronic.

$0.02. I'm sure GM knows this, I'll shut up now.

Completely agree. With DCT we could see shifts in as little as 40 *mili* seconds. I know lot of people here are of the opinion "if it's not manual it's not a sports car", but no human can do that ha.

For anyone interested BMW did a good video/cgi showing how double-clutch works: (they show cutaways halfway through)

Interesting video thanks.

This is a good discussion. I think the C7 certainly lends itself to a dual clutch application without hesitation, but meeting the production deadlines is always tough to pull together for a major vehicle launch. I bet it will show up soon.
