It needs a belt as otherwise, if you want the rear wheel to be central you need a prop-shaft that is offset way over to one side which leads to other compromises such as a much wider cabin or asymmetric seats where only one of the seats is wide enough for an adult or you need to make the seats high enough to be over the prop-shaft. I'd say any problems with the M3W prop-shaft-bevel-box-toothed belt are much more connected with the implementation of the arrangement than the arrangement itself. It's very interesting that the new bevel box comes from a different manufacturer. The new car does look good in the photos and videos. Don't think I'll be rushing out to buy one though.
