"Mated to this powerplant is a fascinating transmission. Although a six-speed autobox does not sound like much these days, the way that BMW has set this up is down right incredible. The thing that makes this transmission monumental is that when in "manual" mode the car cuts the ignition and fuel delivery to individual engine cylinders. So, when you shift it gives the car a little belch and it is seemingly just as quick as a dual-clutch transmission. "

Seems like a good way to get the benefits of DCT without the extra complications. The torque converter also stays locked up so you get the benefits of a direct mechanical drive too.

last time i heard an Audi TT beside me and it had the same sound like "pop" when it changed gear.

That sound is the blow off valves releasing boost on the twin turbos when it shifts or when the driver lifts foot off accelerator.

Personally, I can't stand the sound. That's one reason why I won't own a turbo engined vehicle.
