The next-generation 8 series will be the brand's flagship and will borrow heavily from the 7 series' parts bin.
Autocar says that BMW could go two ways with the 8 series: a four-door hardtop-only design similar to the 6-series Gran Coupe, or a classic two-door coupe and cabrio duo.
It'll be interesting to see if regional markets will play a role in the decision; China pretends that the coupe does not exist as a type of automobile.
The grab of yet another number by BMW is hardly surprising, but what is surprising is how long it took the marque to challenge the Mercedes-Benz S-class coupe head on.
The S-class coupe was called the CL class when the last 8 series roamed the autobahn, but neither big boat was a hot seller in the 1990s.
We'll find out which way BMW will go in 2018 when the automaker will show the first direct 8-series concept.
