I predict the F90 M5 will edge out the CTS-V in a similar comparison because it's lighter than the AMG, but I still maintain that BMW should have stuck to a traditional RWD setup and developed a superior lightweight and balanced chassis with a more advanced traction management system for the RWD for the F90 M5.
People don't realize that the F90 M5 is actually more unbalanced than the F10 M5 too. With the F90 having a 55/45 distribution while the F10 has a 52/48 weight balance.
This comparison in this new Motor Trend video goes to show how much weight really matters but also how much an AWD system matters.
