2023 BMW M850i convertible, do you even need a M8?

The M135i, M240i, M340i, M440i, M550i and M850i are like the S-models at Audi and the 35, 43 and 53 at Mercedes-AMG. Half half and not easy to put it in a category. But maybe just maybe, the M850i is the “half-half” making perfect sense. Could that really be?
