最近谍照记者拍到了下一代宝马4系敞篷车路面测试的照片。虽然车身进行了重度伪装，但仍能看出一些细节。与宝马最近发布的下一代3系趣图相比，这辆4系测试车的车头伪装更多一些，而这两款车共享CLAR平台。可以预计这两款车采用相同的车头设计，包括前脸下部的驾驶辅助系统传感器。向后可以看到这辆4系敞篷车采用了软顶而非现行版的硬顶。这样的变化会让新车重量进一步降低，同样，新的内部结构也将进一步降低车重，这意味着新车将比现行版轻很多。而在车尾，虽然也进行了重度伪装，但仍很可能采用与3系车相同的造型。这两款车和似乎共享了后保险杠和双排气尾管。3系和4系还将共享某些动力系统。宝马已经证实，3系轿车将搭载宝马动力最强四缸引擎，功率可达187千瓦/252马力。除了这台引擎还将提供直列六缸和插电混动系统。新一代3系将在10月巴黎车展亮相，但4系不会同时发布。轿跑车和敞篷车版本将在明年或2020年晚些时候发布。
BMW 4 Series Convertible Spied On The Road, Showing Its Soft Top
These new spy shots provide the best look yet at the next-generation BMW 4 Series Convertible by catching the droptop testing on the road. The engineers keep quite a bit of camouflage on this one, but we can still pick out a few details from the shots.
The front end of this 4 Series test mule has lots of camouflage in comparison to BMW's recently officially released teaser images of the next-gen 3 Series – the two models share the CLAR platform. We can expect the pair of them to look similar up front, including the sensor for the driver assistance system in the center of the lower fascia. Farther back, the latest 4 Series adopts a soft top, rather than the existing hard roof. The change should let the convertible lose weight. The new underpinnings should also shed some pounds, which means the new model could be quite a bit lighter than the current one.
At the rear, BMW's team also keeps this 4 Series under heavy camo, but once again, we can use the upcoming 3 Series as a rough guide. Even in these photos, the two models appear to share the same bumper with matching cutouts for the dual exhaust tips.
The 3 and 4 Series should share some of the same engine options. BMW already confirms that the sedan is getting the company's most powerful four-cylinder powerplant ever, which puts the output in excess of 252 horsepower (187 kilowatts). Inline six and plug-in hybrid choices should join the lineup eventually, too.
The new 3 Series debuts soon at October's Paris Motor Show, but don't expect to see the 4 Series there. The coupe, including its droptop counterpart, could arrive next year or as late as 2020.
