As with any new model release, it's very interesting to see how the new model fares against the predecessor. We were curious how the stunning all-new BMW M6 Coupe (F13) and Convertible (F12) compare to old M6 (E63/E64), so we've compiled a photo and specs comparison. Big thanks to member HKS786 who put together the comparison photos.
