Sad to see M with turbo and V6 but that is something they'll have to do. There is a limitation on I6 design; long block causes cooling issues on the last two cylinders. I believe that is why turbo I6 overheats or limps easy. A V6 is better for turbo application since shorter block allow more efficient cooling on the cylinders.
