I can see sub 5.0 second times form the 335xi primarily due to the new 8 speed auto along with improved traction
mit all four paws. Real world numbers from audiworld & audizine folks from the S4 are mid-high 4's on a stock 2012/2013 with s-tronic doing the shifting (7 speeds, are the shifts quicker than the ZF slushbox?). But there's no way you'll see 4.3 from the xi on instrumented 0-60 mph runs IMHO. It should be a fair straight up fight though. Would love to see slips from two head to head on the strip. With launch control/sport mode there's really not even a "I got a bad launch" excuse available. Anyone who can drive worth a damn can get these bad boys off the line hard so it's going to be car versus car mainly. Well, RT and 60' times always come into the equation. But it'd be a blast to watch!
