最近谍照记者首次拍到了2018款宝马M8敞篷版谍照，谍照记者已经拍到了8系和M8轿跑车的照片，这次又拍到了M8敞篷版照片。这款敞篷车的车头部分与硬顶版一样，有趣的是，车头雷达和传感器位置有所改变，但这只是为应对改变形状后的保险杠的临时措施，而车身其他部分没有变化。而它的织物折叠软顶的后窗有一些改变，相对于目前轿跑车，后窗面积大幅缩小。同时，车顶线条的倾斜程度相对于硬顶敞篷车更平缓，但整体形状一样。据传M8及其敞篷版将搭载两种引擎，包括取自M5的4.4升V8双涡轮，如果真是这样，其功率将达到447千瓦/600马力@5600-6700转/分，扭矩750牛米。另一台V12涡轮引擎功率超过447千瓦/600马力。M8目前仍处于开发早期阶段，宝马表示：”宝马8系和M版本的概念和开发同步进行。“不过，M8及其敞篷版要等到明年底或2019年初才会亮相。而8系标准版将在今年底发布。
2018 BMW M8 Convertible Makes Spy Photo Debut
A fresh new batch of spy photos has just arrived, depicting a prototype of the 2018 BMW M8 Convertible. We've already seen the Bavarian company testing the 8 Series and the M8 Coupe, and this is the first time the most powerful cabriolet from the new 8 Series range is caught out testing.
At the front, the convertible is virtually identical to the hardtop M8 prototypes our photographers have already spied. Interestingly, the position of some of the radars and sensors has been changed, but this could be a temporary solution due to the different shape of the bumper. Other than that, everything here already seems familiar.
Naturally, the cloth folding roof brings some changes to the rear window, which is significantly smaller on the convertible compared to the coupe. Also, the roofline appears to be more gently sloping on the hardtop variant, but the overall shape is similar.
At this point, there are rumors for two potential engine options for the M8 and its convertible sibling. According to some publications, the vehicle will use the revised 4.4-liter V8 biturbo engine of the all-new M5 that was revealed yesterday. If this turns out to be true, then expect to see the same power of 600 horsepower (447 kilowatts) between 5,600 and 6,700 rpm, and 553 pound-feet (750 Newton-meters) of maximum torque.
However, some sources claim it might get a turbocharged V12 with more than 600 hp (447 kW). We stay sceptic on this information until we see something official or manage to obtain leaked details.
The M8 is still in the early stages of development. BMW says “the conception and development of the standard BMW 8 Series and the M model run in parallel,” but don’t expect to see the M8 and M8 Convertible before the end of next year or early 2019. The standard 8 Series should be the first to arrive in the last months of 2017.
