Do any "production" cars (not F1) other than the BMW M3 have a real SMG (no clutch) as an option for transmission?

Sarah Michelle Gellar is overrated as an actress, but still a nice looking woman.

Yep, the MR2 has this option... but it's slower than a real manual transmission, not as well designed as the M3 or Ferrari ones...

Probably like the same one in some of the VWs - basically just an automatic transmission with buttons for you to pretend that it's a manual, but since it's really an automatic with extra crap it's just as slow as an automatic.

No, its actually a SMG, just like the SMG in the Bimmer and Ferrari. The primary difference is, its shifts are slooooww.

Actually it's not... it's a real manual tranmission with the computer controlling the clutch, like the ones in M3 and Ferrari...

But the computer shifts too slowly... any decently good manual driver can shift faster than the computer, which is the reason why it's slower than a real manual...

Here's a link to a SCC article testing it...

Overall it's around 1s slower 0-60 and more than 1s slower in the 1/4 mile...

A closer look at the data shows the SMT to take, on average, almost three times as long to complete an upshift as does our test driver (0.23 seconds vs. 0.61 seconds). Multiply that difference over the length of a solo course or drag strip and you're talking about a lifetime. This simple fact will keep the SMT from being a real performance option.
