What's the difference between a clutchless 6MT and the 7AT? Seems pointless...

Do some research on the topic.

There are some very significant differences between the two if you are looking at it from an engineering and performance perspective.

An AT uses a torque converter. AT's have gotten better, but its still a slushbox by design.

A clutchless manual will still have a disc and pressure plate, along with some mechanism (usually hydraulic) to engage/disengage.

In addition, some of the clutchless units have dual discs and shafts, allowing gear selection to be staged, with a net effect of *very* fast shifting, far faster then an AT. VW has this.

Its not just a technology for Ferrari, Porsche (PDK), and BMW (SMG): VW has had it for a few years now. You can get it on a TDI even. I think Nissan
only uses it in the US on the GTR, and that transmission is complicated by
the AWD system and other factors, it won't see duty in a Z ever.

It remains to be seen over time if this trend will increase or not: initially there is added complexity and engineering that goes into it. Early units were not as smooth in stop/go traffic as a AT but that is getting better with each generation. Some think a true manual is going the way of the dodo.

In the US, I tend to agree with that based on sales numbers and the number of people who utterly cannot drive out there.

In a perfect world, it would be mandated that every car has a manual (a few exceptions of course)...this would drastically cut down on the narcissists with their cell phones while driving. People would still do it, but it would be far less.

Thank you. The difference is the torque converter.

The last generation of the Toyota MR2 had an optional clutchless 6 speed.

A DCT with launch control would be the same thing.
