在一个潮湿，寒冷的清晨，宝马8系敞篷版原型车被拍到在纽伯格林赛道进行测试。宝马有90%可能性会推出M8敞篷版，功率约为600马力并标配全驱系统。不过这辆测试车并非M8，它很可能是840i，搭载宝马传统的3.0升直列六缸引擎。现在还不清楚，为什么8系的后玻璃窗要进行遮盖。或许很多人会认为，折叠织物软顶是假的，量产版将采用顺滑的金属硬顶，就像4系车一样。但考虑到奔驰S级敞篷版也采用软顶，8系没理由不这样。8系将在德国丁戈尔芬投产，该车将于明年夏季发布。8系与7系共享平台，高端版本将搭载取自M760Li的610马力6.6升V12引擎。

2019 BMW 8 Series Convertible Spied Lapping Damp Nurburgring

On a damp, cold morning, the BMW 8 Series Cabriolet prototype was filmed testing at the Nurburgring track.

we can say with 90% certainty that there will be an M8 Cabriolet, packing around 600 horsepower and a standard AWD system. But this isn't it; we're more likely looking at something like an 840i with BMW's traditional 3-liter inline-6 engine.

Trademarks have been filed for all kinds of different models, including a suggested 830d with a single-turbo diesel-6. But not all of them will be available at launch.

We're not quite sure why part of the 8 Series' rear glass is camouflaged, though some people have suggested the folding fabric roof is just a dummy and that the production car will have a sleek metal cover, just like the 4 Series. But that doesn't really make sense since even the S-Class can get away with pitching a tent.

Production of the 8 Series model range will take place at BMW’s main factory in Dingolfing, Germany. The official reveal is scheduled to happen in 2018, most likely around this time.

The 8er will be based on the same platform as the 7 Series flagship sedan. Its most high-end version is expected to be equipped with the 610-hp, 6.6-liter V-12 engine that debuted this year in the M760Li.
