I agree that as a community or fact source we need the official fact sheets to call it but two sources stating Biermann with the standard BMW I6 numbers and references to the 1M with that the S55 share only bore x stroke plus a few others is enough for me personally, i.e I believe the S55 has the same bore stroke as the standard I6s of 84 x 89.6
