We've now had confirmation of the s55 engine's sightly above 7500 RPM redline via the
official released specs, but seeing as how the tachometer and redline were ever elusive all these months and years of spy photos, we're happy to finally share with you images of the M3/M4's redline.
Though the actual redline starts at the 7500 mark, expect the rev limiter to kick in a bit after that.
