Yes, a four-door BMW M8 really is happening.
It's a busy time for BMW right now. Customer deliveries of the 8 Series Coupe have begun, while its Convertible sibling will arrive in March. Later down the line, the 8 Series will also spawn a high-performance M8 for the first time in the model's history later this year to replace the M6 Gran Coupe.
We've already seen official teasers and spy shots of the M8 Coupe, but now our spies have spotted the upcoming production M8 Gran Coupe undergoing testing just under a year after the M8 Gran Coupe concept debuted at Geneva. Yes, a four-door BMW M8 is really happening.
We're most likely looking at a near-production prototype, although there's still a lot of camouflage covering the exterior. A section of the hood has been left uncovered, however, showing off the car's aggressive air intakes. The quad exhaust tips also indicate we're looking at an M-powered 8 Series, and the overall design looks very sleek. If you're looking for a BMW M car that's more potent, practical and premium than the new M5, the M8 Gran Coupe will fit the bill.
Like the standard Coupe and Convertible, the M8 Gran Coupe will be powered by a 4.4 liter twin-turbo V8 that will deliver around 600 - 630 hp. There could also be an even more powerful Competition version in the cards, but it remains to be seen if it will be available at launch.
Bigger brakes and wheels should give this beast plenty of stopping power. BMW has already confirmed the M8 Coupe will arrive this year, so we could see its more practical four-door sibling debut either later this year or in early 2020.
