This is something I have always been curious about.
Yes it goes back to DSG vs 6MT, but seriously...
If you launch DSG normally, it runs a 0-60 which is about 0-0.1 second faster then the 6MT. It's not until you use LC that you see the benefit of a DSG launch.
That thought in mind, is the XDS helping us in our launches? Or sandbagging it? Just a simple summary, XDS will act like a limited slip, however instead of spinning a tire faster etc, it will apply appropriate braking.
I have tried turning off 'all' traction control systems but I am pretty sure XDS is not part of shutting off everything.
I'm sure Cobb and UM won't tell us what their secret sauce is, but I am very curious on this. Launching at 4,000 RPM isn't a big thing, and it's a matter of learning to slip the clutch, no doubt about it...but there is something electronically that is sand bagging the 6MT, and I have this *hunch*.
It would be tough to do a *like for like* but I believe the MK6 R didn't have XDS, but it was down on power + different chassis + weight etc...same transmission. I feel like a clue would be there though
