Solving for X, 4.84 x 317 = 1,534 kg
So, DCT is 37 kg or 81.6 lb heavier than manual tranny. Sounds about right.

I think that sounds about right also.....given the info we have at the moment. The performance advantage of the DCT is getting smaller and smaller. A couple of things are interesting to me: First there is rumor that there will be a light weight M3 version come out and that they will use the 6 speed manual only where they used the DCT in the E92 GTS/CRT. A flip in philosophy? Second they are putting some type of paddle shift trans in the new M235 race car. That would be a game changer if they can develop a DCT that can handle racing.
