That remains to be determined. In for example the Golf R32 DSG the down changes aren't that smooth.

...but better than SMG

You dont really use automatic mode very often in the M5. Manual mode is what the owners prefer and use most of the time, at least the ones I talked to and when I read on m5board.com.
If you dont have the gearbox put on the fastest gear shifting in manual mode you can drive the car smoothly. When I drove the M6 in the city and in manual mode, you can change the gear smooth without jerkiness.
But as soon as you put on the fastest shifting settings the gearchange can be jerky. But that is the point with faster shift settings since the gearbox is racing inspired.
I bet DCT will behave excalty the same as SMG (if not, it lost some of its charm and fun) with the fastest shiftings but of course with improved gearchanges in Automatic mode.

I think that the sequential gearbox mounted in the 430 Scuderia is the benchmark now. Extremely fast and smooth gearchanges, "similar" to current F1 gearboxes, where you don't feel the gear changes.

probably the first time I hear that a sequential gearbox change gears smoother/or smooth as a normal automatic. Great news for DCT, then we know it will be good.

But the Audi was the WINNER of this test.

Long before the M5 went into production I always thought that BMW should use some kind of turbo technology with that V10. Same goes for the new M3. Torque is what moves the car and this test shows it…
Rs6 for me : )

Who is the winner of the test is not as important (well, it is of course fun) as what is revealed during the testing - in this case the BMW seems to have the edge in the categories that matter for CorpusCallosum.

Put in a Skoda Fabia in this test and i bet you will be able to find a tester that says the Skoda is the winner, based on his or her preferences.

Well the RS6 came three years after the M5 so Audi had plenty of time to study and develop their car,expected result.

The thing is that they probably didn't want to do a car similar to the M5, according to what it's written in this test about how the car goes, they wanted to do a car previous RS6 owners will feel familiar with.

I think you are completely right. Why would Audi try to make a mimic of the M5 when they already got a stable and loyal base of customers looking for a car with characteristics quite different from said M5? That makes no sense.
