Well, I guess it is good marketing, but it's a development and more effective and becoming more popular.(Original post by 1992LP)
Very good marketing, and may make a little bit of difference on a race track, but exactly how much of a difference does it make in the real world?
They offer the 'best of both worlds'. You can leave them in drive which is fully automatic for when you aren't in a hurry or in traffic etc, or you can manually change gear with the paddles.
You don't have to take your hands off the wheel, so that can be seen as a positive.
They are faster at changing gear than you can manually, which although most people may not notice, is an improvement.
I've only been in two cars with these gearboxes (as a passenger), a Golf GTI and an BMW M3, both drivers drove manual cars before/at the same time, but really liked the DSG/SMG, so there must be something in it.
You can drive them on an automatic license too, which is why I like the idea of them.
