Holy moly the M5 is powerful. Not surprised the higher displacement benz makes more outright torque, but the M5 holds its torque for longer. I wonder if the S63tü is near its limits in stock form because it seems like tuners are able to extract more from the M157 easily than the S63Tü. Still amazing what only 4.4 liters was able to do against the big boys!
