BMW M5 E60 vs BMW M6 F12 PP-Performance 726hp
Here we have venerable naturally aspirated S85 5.0 liter V10 going up against the new twin turbo S63TU 4.4 liter V8. The convertible M6 is tuned by PP-Performance and the S85 V10 with bolt ons simply will not be able to match the power output and torque of a tuned S63TU. It shows with the M6 taking every run decisively although the M5 shows well considering its bolt on modifications (exhaust, pulley, filter, scoops) and no ecu tune or headers.
Would the M5 do better with an aggressive tune and headers? Absolutely. Would the M6 do better with exhaust modifications other than being tune only? Absolutely. Keep in mind this is also the F12 M6 convertible and not the coupe which means the M6 is carrying roughly an extra 300 pounds.
It is interesting to note that in the final run where they go up to what appears ~180 miles per hour the M5 inches back. Not nearly enough to make up the ground but it shows the top end strength of the S85 V10 even without forced induction. Still, bolt on S85's are not going to beat tuned S63TU's with the power, torque, and shift speed of the dual clutch transmission working against them.
