宝马近日正式发布了2018款M5，该车搭载一台升级版4.4升V8双涡轮引擎，功率447千瓦/600马力@5600-6700转/分，扭矩750牛米，高于老款车的428千瓦/575马力和677牛米。由于功率增加，新款M5百公里加速时间仅需3.4秒，最高时速仍为250公里，如果拿掉限速器，最高时速可提升至305公里。与引擎搭配的是新的八速MSteptronic自动变速器，可提供经济、运动和运动强化三种模式。该车还标配MxDrive全驱系统，可提供四驱、四驱运动和两驱三种模式，甚至可以关闭稳定控制系统。新车外观变化不大，车头仍保留双肾格栅，但前大灯进行了改款，尾部的散流器位置更低，与包括M2在内的其他M版车型保持一致。尾灯组升级明显，散流器尺寸更大，底部仍是四排气尾管。车身侧面可见标配的19英寸轮圈，可选装20英寸轮圈，搭配米其林Pilot Sport cup轮胎。消费者可选装碳陶瓷刹车盘，重量将降低23公斤。新车整备质量约为1856公斤，比老款车降低90公斤。它的车顶和车身采用聚合物与碳纤维材质，有助于进一步降低车重。车厢内采用了新的方向盘，座椅和内饰，更突出运动风格。方向盘和中控台部分采用碳纤维装饰和红色边框。该车在欧洲起价117900欧元（约合人民币92.78万元），将于9月开始接受预订，明年春季交付。
2018 BMW M5 Packs A 600-HP Punch, Standard All-Wheel Drive
The wait is over. Following a series of leaked images and video, spy shots, and teasers, the new BMW M5 is officially here – and it’s powerful. Using an updated version of the outgoing version’s 4.4-liter biturbo V8, the new M5 produces an impressive 600 horsepower (447 kilowatts) between 5,600 and 6,700 rpm, and 553 pound-feet (750 Newton-meters) of maximum torque. That number is up from the 575 hp (428 kW) and 500 lb-ft (677 Nm) of torque found on the previous model.
With all that added power, the new M5 can sprint to 62 miles per hour (100 kilometers per hour) in just 3.4 seconds, and will continue on to a top speed of 155 mph (250 kmh)… or 189 mph (305 kmh) if you remove the limiter. Power is routed through a new eight-speed M Steptronic automatic gearbox, with a trio of optional driving modes: Efficient, Sport, and Sport Plus. Power is sent to all four wheels via an M xDrive system, with the option to cycle between 4WD, 4WD Sport, and 2WD, and even the ability to turn off the stability control entirely.
The exterior, as noted by the leaked images, receives a subtle but noticeable update over the outgoing model. The dual kidney grille remains, naturally, with new headlights, and a lower diffuser in line with current M models like the M2. In the rear, the taillights have been updated significantly, and a larger diffuser is now present. The same quad exhaust tips carry over.
A set of 19-inch alloy wheels come standard, with the option for 20-inch wheels wrapped in Michelin Pilot Sport cup tires. Buyers can opt for a set of carbon ceramic brake discs at an extra cost, which trim the overall curb weight by a cool 50 pounds (23 kilograms). The new BMW M5 tips the scales at just 4,089 pounds (1,085 kilograms), shedding nearly 200 pounds (90 kilograms) over the outgoing model (4,287 pounds / 1,945 kilograms). Polymers reinforced with carbon fiber (PRFC) elements in the roof and throughout the bodywork are in part to thank.
In the cabin, new features like the steering wheel, seats, and upholstery give the M5 an even sportier feel. Portions of the steering wheel and center console, meanwhile, come standard with a carbon fiber trim accented with a red outline.
The new BMW M5 will start at €117,900 in Europe, with orders beginning this September, and deliveries following in Spring of 2018.
