最近谍照记者在斯堪的纳维亚半岛拍到了正在测试的2017/2018款宝马M5，当时车辆全身都采用了云纹伪装。这辆高性能轿车的外观非常内敛，采用了突出双肾格栅，而轻质合金轮圈则满足了其高性能制动系统的需求。车尾采用四排气运动尾管，车身带有“政府批准高速安全测试”字样。该车将搭载一台4.4升M TwinPower Turbo V8引擎，现行版功率为560马力，但先前有报道称，新车功率将提升至626马力。后驱仍为标配，但全驱将首次作为选装件。除了功率大幅提升，下一代M5由于采用缩短后的7系车平台，因此车重将进一步降低，整车质量将比现行版降低220磅（约合100公斤）。由于车重降低，新车加速性将更突出，现行版0-96公里/小时加速时间4.2秒，最高时速155英里（约合250公里）。

 

BMW M5 spied, could have up to 626 hp

The 2017 / 2018 BMW M5 has been spied undergoing cold weather testing in Scandinavia.

 

Dressed in swirly camouflage, the high-performance sedan has a fairly restrained appearance but features a prominent twin kidney grille and lightweight alloy wheels that are backed up by a high-performance braking system. The model also features a four-tailpipe sports exhaust system and a badge that signifies the car is doing a "Government approved high speed safety test."

 

Speaking of speed, power will be provided by an upgraded version of the company's 4.4-liter M TwinPower Turbo V8 engine. It currently produces 560 horsepower but previous reports have suggested the new engine could develop up to 626 hp. Rear-wheel drive will be standard but all-wheel drive is expected to be offered as an option for the first time.

 

Besides being significantly more powerful than its predecessor, the next-generation M5 will be lighter as it will ride on a shortened version 7 Series' platform. This could enable the model to weigh as much as 220 pounds less than the outgoing M5.

 

Given the weight loss and extra power, the new model will easily outgun its predecessor which runs from 0-60 miles per hour in as little as 4.2 seconds before hitting a limited top speed of 155 mph.
