2018 BMW M5 Prototype Reveals Three Taillight Brake Patterns at Nurburgring

And while we've shown you the F90 M5 testing on the Green Hell on multiple occasions, we didn't get the change to focus on its... brake light patterns.

As you'll be able to notice in the Ring footage at the bottom of the page, the 2018 M5 prototype displays three different taillight braking patterns. The first is what we'd call a "classic" one, where the outside clusters are lit (you can see an example at the 2:50 point).

Next up, we have what appears to be the "emergency braking" type, which sees those outer clusters flashing (examples shown at 0:59 or 1:42). This seems like a normal modern era pattern for decceleration that goes past the ABS threshold, but we can't say the same about the third scheme revealed here.

If you jump to the 0:45, the 1:55 or the 3:00 point, you'll notice the outer clusters (on the fenders) lighting up together with the inner ones (mounted on the boot lid).

Sure, frame rate mishaps can sometimes trick us into believing cars flash their light at the camera, but this doesn't seem to be the case here. And while we know BMW enjoys experimenting with new-age lighting solutions, such as the BMW i8 laser headlights or the organic LEDs used for the M4 GTS taillights, this still doesn't help with explaining the three-way scheme shown by the F90 M5 Nurburgring tester.

Oh well, until we get to find out more on this overly Red topic, we're inviting you to enjoy the manic sprints of the 600 hp, all-wheel-drive M Division sedan.
