As we know BMW is planning to stretch its line-up (what’s one more car when you’re already making dozens of different nameplates) by using the 7 Series to spawn the 8 Series.

Obviously going by history, and facts, the 8 Series is a two-door, 2+2 seater Gran Turismo that was first produced between 1989 and 1999 as Munich’s flagship motor, so it’s only normal to assume the new 8 Series will follow in similar fashion.

However it would be foolish to forget how much carmakers love niches, so besides a coupe version, BMW will also stretch its 8 Series line-up to include a four-door saloon, or if you go by their take on it, the 8 Series Gran Coupe.

BMW has just unveiled the M8 Gran Coupe concept at the Geneva motor show, giving us a big clue as to how the production ready version will look because the Muncheners tend to leave their concepts mostly alone when readying them for the showroom. Which means we’re in for a good thing, because this M8 Gran Coupe doesn’t loo too bad at all…

“The BMW 8 Series will take over as the new flagship model of the BMW line-up and, as such, combines unsurpassed sportiness and elegance,” says BMW’s design boss Adrian van Hooydonk. “The BMW Concept M8 Gran Coupe offers a look ahead to the most exotic and alluring variant of the new BMW 8 Series.”

As the brand flagship, then, the 8 Series has a lot to live up to, but what is kind of curious is that this four-door Gran Coupe version will come based on the two-door 8 Series that’s in turn based on the four-door 7 Series. So really, it’s just a swooped 7 Series, though you wouldn’t say no to it.

The big highlights are the equally big kidney grilles, low headlights, and some huge air intakes done in composite materials, and even if BMW is still keeping the technical specifications a surprise, it’s safe to assume the M8 will bank on a twin-turbocharged V8 making upwards of 600 horsepower, while electrified models also seem likely.
