Crosstown Rivalry: M5 F10 vs CLS63 AMG

Oh, this should be a good one. Both the M5 and the CLS63 AMG get their power from boosted V8s. They both make a similar amount of power, and they both weigh about the same. What else is there to do but take them to the drag strip and have them run it?

Watch these natural rivals race in the video below. I don’t know why, but my money is on the M5.
