Yeah apparently the MSS60 has no issue driving the S85, and has all the DCT stuff already baked in. Definitely a couple of them around. If my S65 ever meets its demise I'm definitely putting an S85 in my car.Its a straight bolt up, electronics wouldn't be hard for someone like Tom from jpl, pretty sure he done it already on a customers car.
But why not the M5. Then you can stick you homies in the back with comfort.It will be much cheaper and better to get a hard top m6 and stick a dct in that than trying to massage it all into a 135, engine is just to heavy and the wheelbase to small for a v10.
It would handle like shit unless all you want to do is drift and it would be a handfull at the best of times.
But it is the sweetest sounding engine to date from BMW.
