The German brand is looking to hone the big car's sporty characteristics by studying its steering, braking and acceleration behaviour that will provide feedback for development of the upcoming M8 produced by the maker’s performance arm.
“The test drives under the most severe conditions show that we are right on target with our concept for the new BMW 8 Series Coupe. The vehicle dynamics values already achieved are absolutely impressive. Our customers and fans can look forward to a genuine sports car,” says Klaus Fröhlich, a member of BMW's board.
First revealed in concept form at the 2017 Concorso d'Eleganza on the shores of Lake Como, Italy, the 8 Series announcement marked a surprise return of the German carmakers range-topping two-door since its demise in 1999.
The coupe will give BMW a direct rival to the Mercedes-Benz S-Class Coupe and the Bentley Continental GT as well as a new factory-backed race car, the M8 GTE, which will make its debut at the Daytona Rolex 24 next week.
Sitting atop the production range will be the M8, with the company's tuning division equipping the coupe with a twin-turbocharged 4.4-litre V8 petrol engine.
Expect the range to mimic the 7 Series with all models to receive an eight-speed automatic transmission and higher-specified models like the 840i and 850i will more than likely have the choice between rear- and all-wheel drive.
The production-version of the 8 Series is likely to break cover at one of the big European shows this year: either the Geneva Motor Show in March - which is known for supercar and ultra-luxury vehicle reveals - or the gigantic Paris Motor Show in September.
