Re: automated manual trans---
Assuming no changes in trans performance, then yes, the trans can be adapted to, it is driveable, and I'm sure the smartie enthusiasts/gearheads on this website will have no problem with it. I'm thinking of the average American driver, used to a slushbox, who can't even drive a manual, & now looking for a city/mileage car, wandering into a smart dealer and taking a test drive. A two to three second lag in the first upshift is going to be a killer, not to mention the noticable increased rpm before the car begins moving. This consumer will have no interest in adapting or shifting with the paddles, to them this is just another automatic and they aren't going to like it. They'll be on their way to the Honda, Chevy, or Toyota dealer.......
MB knows how to build great transmissions, I suspect the performance quirks are related to the packaging--the whole powertrain has to be about 30% of the volume of the average subcompact's. And there are some great automated manuals out there, go to the VW dealer and test drive a Jetta or Golf with the dual-clutch DSG auto/manual trans, this trans is absolutely first-rate. Of course, maybe the smartie should just stay in the hands of enthusiasts, or maybe thats the point. I know I'm going to drive ours in the manual mode anyway.
