最近谍照记者在纽伯格林赛道第二次拍到了8系原型车测试照片。这次该车采用了新的轮圈，车身离地间隙更低，车辆前后部增加了更多空力套装，这表明，该车似乎是一辆“M”版车型。与先前拍到的原型车一样，该车的车身很长，很漂亮。车身后四分之三部分的设计结合了M1和现行版i8，前后端造型都比6系车更具有雕刻感。如果宝马决定恢复8系车，该车将搭载4.0升V8双涡轮或动力更强的V12引擎，可提供后轮和全轮驱动，这两台引擎的功率都能达到447千瓦/600马力，预计车辆0-96公里/小时加速时间不到4秒。包括M8在内，宝马8系车可能有多达五款车，包括825/830/850/860/M850。
Possible BMW M8 Spied On The Nurburgring
Spotted testing on the Nurburgring, this is the second time we’ve seen the proposed 8 Series prototype out and about on public roads. This time, it wears a new set of wheels, rides much lower to the ground, and sees some aerodynamic additions to the front and rear, suggesting it could be a high-performance 'M' car.
Like previous prototypes before it, its body is long and lovely. The rear three-quarter shares some design cues with the iconic M1 and the current i8, and both the front and rear ends are more chiseled than other 6 Series' before it.
If (or when) BMW does decide to revive the 8 Series, it could come with either a 4.0-liter biturbo V8 under the hood, or a more potent V12. Both rear-wheel drive and all-wheel drive would be available, and the two engines could produce as much as 600 horsepower (447 kilowatts) each, propelling a proposed M8 to 60 miles per hour (96 kilometers per hour) in "well under 4.0 seconds."
Along with a high-performance M8, BMW's 8 Series range could include as many as five different designations. The German automaker has trademarked the monikers 825, 830, 850, 860, and M850.
