With the very broad power plateau of the S55 compared to the peakier power curve of the S65, the shorter ratios of the DCT will have less benefits on the F8X.
Further, according to the press release, the 6MT on the F8X is a brand new desing shaving 26lb compared to the previous 6MT. This means that a 6MT equiped F8X will have a 70lb advantage over a DCT car (assuming the DCT on the F8X is a carry over from the E9X). This is not negligible.
From a performance perspective, the DCT still has the benefits of the shorter gearing, quicker (instantaneous) shifts and ability to keep both hands on the steering wheel. But I feel the DCT will not provide as much of a performance advantage as it did on the E9X.
I am still on fence on which one to order
