BMW has revealed the sleek silhouette of its upcoming four-door 8-Series.
The German brand issued a hazy teaser image of the M8 Gran Coupe Concept on social media ahead of its public debut at next week's Geneva motor show.
It has yet to confirm any information about the car, but it clearly indicates a four-door version of the bold new 8-Series range that will likely make it into production as a replacement for today's 6-Series Gran Coupe.
BMW will revive the 8-Series range this year in a bid to move its flagship coupe, convertible and the four-door Gran Coupe models up a notch to challenge the likes of the Mercedes-Benz S-Class Coupe and Cabriolet, as well as the Bentley Continental GT and GTC.
It has already revealed a concept version of the two-door while the racing version made its debut at the Daytona 24-Hours in January as a build-up to BMW's return to the Le Mans 24-Hour in June and the World Endurance Championship.
The Gran Coupe looks to follow the sleek profile - and mimic the Aston Martin Rapide - with an extended roofline that falls into a shallow boot with an integrated lip spoiler.
All versions of the M8 are expected to utilise the same mechanical elements of the recently-introduced new-generation M5 that goes on-sale in Australia next month, including its upgraded 4.4-litre twin-turbo V8 and all-wheel drive transmission.
More details of the BMW M8 Gran Coupe Concept will be revealed next week. Stay tuned to Drive.com.au for all the latest news from the 2018 Geneva motor show.
