2021 BMW M5 CS spy shots and video

BMW’s 5-Series received a round of style and tech updates for 2021, and those same updates affect the high-performance M5 variant.

We’ve already seen the updated versions of the regular M5 and slightly sportier M5 Competition, but there’s also a new performance flagship coming that will likely carry the M5 CS designation. A prototype for this flagship has been spotted.

The prototype may look like earlier testers for the regular M5 but if you look a little closer you’ll notice some key differences.
