宝马近日公布了2018款M550i xDrive价格，该车起价为72100美元（约合人民币49.9万元），另外还要加上995美元运费和手续费，该车售价比核心竞争车型奔驰-AMG E43低300美元。该车搭载一台4.4升V8引擎和双涡管涡轮增压器，功率340千瓦/462马力，扭矩650牛米。而奔驰E43搭载一台3.0升V6引擎，功率295千瓦/396马力，扭矩520牛米。车辆百公里加速时间3.9秒，而奔驰E43为4.5秒。宝马m550i速度更快，这部分得益于该车搭载的xDrive全驱系统。另外由于该车采用新的CLAR平台，车重大幅降低。宝马将于下月开始接受，最初将提供185千瓦/248马力和250千瓦/335马力两种车型，一个月后将提供M550i xDrive和530e iPerformance环保车型，后者起价51400美元（约合人民币35.56万元）。

2018 BMW M550i xDrive is cheaper, quicker than Mercedes-AMG E43
BMW has announced the pricing details for the current flagship variant of the 5 Series family. The stunning 2018 BMW M550i xDrive will be available for at least $72,100 plus $995 destination and handling, which makes it only $300 cheaper than its main rival, the Mercedes-AMG E43.

The M550i xDrive is powered by a massive 4.4-liter V8 biturbo engine with two twin-scroll turbochargers, good for 462 horsepower (340 kilowatts) and 479 pound-feet (650 Newton-meters) of torque. Just for a comparison, the E43 AMG has a 3.0-liter V6 under the hood with 396 hp (295 kW) and 384 lb-ft (520 Nm). Given that, it’s no surprise the Bavarian business sedan is significantly quicker in the 0-62 miles per hour (0-100 kilometers per hour) sprint – 3.9 seconds versus 4.5 seconds.

We can all agree the M550i xDrive is quick, very quick. In fact, it’s quicker than the outgoing M5 by at least two tenths. That’s possible thanks in part to the xDrive all-wheel drive system, which channels the power from the motor to all four wheels. A significant weight reduction because of the new CLAR architecture also plays a major role.

BMW will start accepting orders for the new 5 Series range starting next month. Initially, two petrol engines will be available, offering 248 hp (185 kW) and 335 hp (250 kW) respectively. A month later, the M550i xDrive and the eco-friendly 530e iPerformance will join the range with the latter starting at $51,400.
