最近谍照记者在南欧拍到了正在进行炎热气候测试的宝马M4，新车将作为2018款车型于明年发布。从这辆原型车照片看，M4改款车将采用M4 GTS的某些设计元素，包括前扰流唇和带有散热孔的引擎盖。该车照明系统也将获得升级，采用全新造型大胆，而且这样的改款也将应用于整个4系车。虽然采用M4 GTS引擎盖意味着动力系统的升级，但现在还不清楚内部将有怎样的变化。M4 GTS与M4搭载了相同的3.0升直列六缸涡轮引擎，由于部分采用了水喷射技术，功率493马力，扭矩442磅-英尺（约合600牛米）。、虽然现在无法预期M4是否会采用水喷射技术，但预计新车功率将从目前的425马力提升至444马力。而目前的2017款车型如果想要将M4功率提升至444马力则需要订购Competition套装。车厢内预计将提供取自M4 GTS轻量化套装作为选装件，包括轻量化座椅和中控台。这也是现行版M4的最后一次升级，宝马将于明年发布新的3.0升引擎，而新一代4系，包括M4则将在未来一到两年内发布。

 

2018 BMW M4 spy shots

A prototype for an updated version of the BMW M4 has been spotted undergoing hot-weather testing in southern Europe.The cars should be introduced next year as 2018 models.

 

The prototype reveals that the updated M4 will be receiving some of the mods fitted to the high-performance M4 GTS, such as that model’s front lip spoiler and vented hood.

 

The updated M4 also looks to be receiving some tweaks to the lights in the form of new graphics. The tweaked lights will be common across the updated 4-Series range.

 

It’s not clear what mechanical mods are planned though the addition of the M4 GTS hood may hint at an uprated powertrain. The M4 GTS features the same turbocharged 3.0-liter inline-6 as the M4 but delivers an impressive 493 horsepower and 442 pound-feet of torque, thanks in part to a water-injection system.

 

While we don’t expect the car to adopt the water-injection system, we may see power lifted to 444 hp, up from the current 425 hp. At present, the 444-hp rating can be added by ordering the Competition Package announced for the 2017 model year.

 

In the cabin, we can expect some new trim options including possibly some lightweight options like those in the M4 GTS, such as the lightweight seats and center console.

 

This should be the final update for the M4 before a successor is introduced. A new 3-Series arrives in 2017, and a new 4-Series, including a new M4, should follow a year or two later.
