Probably a V8 gas FAS type system.

Here's a continuum on "refinement & shift feel" from "coarse" to "smooth"
manual trans ---> automated manual (MTA) ---> dry DCT ---> wet DCT ---> step gear automatic ---> CVT
Most American drivers who are accustomed to step gear automatics would find MTAs objectionable. European drivers who are used to manuals have adapted to them well and will more than likely do the same with DCTs.
Dry DCTs have a fuel economy advantage over MTA, wet DCT, and similarly sized step gears. Wet DCTs give back a bit of that fuel economy in parasitic losses in exchange for better shift feel. Cost is all over the map, depending on the size of the application. Take a look at the Nissan GT-R supercar. It has a 7-speed DCT that is so big and heavy they apparently had to lengthen the car to fit it. This is primarily due to the amount of torque the gears have to handle. On the other hand, VW is doing some amazing things with relatively small, low torque FWD applications.
Peace,
