Beyond those changes, stripping away some of the camouflage has shown modest tweaks. We're finally getting a good look at the updated, squared-off LED running lamps and the tweaked front fascia. Updates are even more minor in back. But there may be something more drastic at play with the taillights. Studying these shots, we can't really see any detailing in the rear lamps. There's a similar thing going on between the normal LEDs on the BMW M4 and the OLED units in the new M4 GTS. Backing up this speculation is a single shot of one of the rear turn signals illuminated. It doesn't look quite like the current car's signal, but we can't be certain.
It's possible that the shots and the camouflage might be playing tricks on our eyes. And since this is the first time we've seen the updated M5 with production taillights, there's no real basis for comparison. Still, BMW's tantalizing new OLED tech is sure to proliferate beyond the M4 GTS. We just can't yet be certain if it's coming to the next M5.
