最近谍照记者在纽伯格林赛道拍到了正在进行性能测试的2018款宝马M5，该车拿掉了很多伪装，可以看出它采用了侵略性前保险杠，更大散热孔，外延轮拱以及新的M侧后视镜盖。取自M6轿跑车的碳纤维车顶隐藏在塑料伪装下面，而在车尾可以看到扰流器设置在行李箱盖上。硕大合金轮圈搭配升级版制动系统，车尾四排气尾管从散流器下面伸出。这辆原型车比标准版5系车身更低，整体看起来比M550i xDrive 更具侵略性。新一代M5预计将采用改进版的4.4升V8双涡轮引擎，功率超过600马力，搭配xDrive四驱系统。与引擎搭配的八速双离合变速器使该车百公里加速时间不到3.6秒。虽然相对于奔驰E63 S百公里加速时间的3.4秒没有什么优势，但宝马未来还将提供Competition动力升级套装。新款M5将于年底前发布，最早会在9月的法兰克福车展亮相。
2018 BMW M5 Continues Camo Striptease In Latest Spy Photos
While we don’t need a crystal ball to broadly figure out how the new M5 is going to look like, nevertheless we are still happy BMW has decided to remove some of the disguise during the latest round of testing on the challenging Green Hell. The high-performance midsize sedan is still wearing a lot of makeup, but even so we get the chance to check out the aggressive front bumper with those beefy air vents as well as the bulging wheel arches and the new M side mirror caps.
An M6 Coupe-derived carbon fiber roof is hiding underneath that psychedelic camo while at the back a discreet spoiler has been glued onto the trunk lid. Bigger alloy wheels matched by upgraded brakes are also on the menu, as are the quad exhaust tips flanking what looks like a diffuser. The prototype also rides substantially lower than the regular 5 Series models and overall it looks a tad bit more menacing than the temporary range topper, the M550i xDrive we had the pleasure of reviewing earlier this month.
Speaking of which, the new-gen M5 is expected to use an evolution of the same biturbo 4.4-liter V8 engine developing in excess of 600 horsepower according to the latest intel. For the first time ever, all that M power will be channeled to an xDrive setup, but there will still be a way to punish the rear tires and make the M5 tail-happy.
Responsible for putting all that power onto the road will be an eight-speed, dual-clutch automatic transmission helping the M5 hit 62 mph (100 kph) from a standstill in less than 3.6 seconds. That might not sound overly impressive considering the Mercedes-AMG E63 S Sedan completes the task in 3.4s, but BMW will likely respond to that later on with a Competition Package.
Meanwhile, the standard M5 should bow before the end of the year and we might see it in the metal as early as September at the Frankfurt Motor Show.
