宝马 520d EfficientDynamics看起来与其他5系车没什么不同，但只要看过了规格表，就会明白该车的卓越之处。这是一款最省油的非混动车型，该车百公里油耗3.9-4.3升，每公里二氧化碳排放量102克至114克。而530e插电混动车百公里平均油耗2升，每公里二氧化碳排放量46克。当然，530e的加速性更优异，百公里加速时间6.2秒，而520d EfficientDynamics为7.5秒。不过这两款车的最高时速都是235公里。该车搭载一台2.0升柴油引擎，功率140千瓦/190马力，扭矩400牛米，标配八速Steptronic变速器。低油耗是由于该车配备了CLAR平台，重量进一步降低，而选择性催化还原催化转换器及汽车尿素的使用也进一步提升了车辆的燃油经济性。目前还不清楚该车售价，但可以肯定将超过520d的49650欧元（约合人民币36.34万元）。该车将于3月在欧洲上市，届时M550i xDrive高性能版和530e插电混动车也将同时上市。
BMW to launch thrifty 520d EfficientDynamics Edition in March
It looks virtually the same as all of the other regular 5 Series models, but the 520d EfficientDynamics stands out once you check out its specs sheet. That’s because it is the most frugal non-hybrid model of the range by managing to consume between 3.9 and 4.3 liters / 100 km with corresponding CO2 emissions varying between 102 and 114 grams.
For the sake of comparison, the 530e plug-in hybrid consumes on average a mere 2 liters / 100 km and emits 46 g/km. The electrified version is also considerably quicker in the sprint, managing to reach 62 mph (100 kph) in 6.2 seconds whereas the 520d EfficientDynamics needs 7.5 seconds to accomplish the same task. Coincidentally, the two cars have the exact same top speed: 146 mph (235 kph).
The economical diesel-powered BMW 5 Series has a 2.0-liter engine developing 190 horsepower (140 kilowatts) and 295 pound-feet (400 Newton-meters) of torque delivered to road via a standard eight-speed Steptronic transmission. The low fuel consumption was possible after making the switch to the CLAR platform slashing a serious amount of weight, while the implementation of a selective catalytic reduction (SCR) catalytic converter with AdBlue further improved the car’s efficiency.
Pricing isn’t out yet for the 520d EfficientDynamics model, but it will surely command a premium over the 520d available in its domestic market from €49,650 with the aforementioned Steptronic gearbox.
BMW will have the thrifty 5 Series diesel on sale in Europe starting from March when the hot M550i xDrive and the 530e plug-in hybrid will also be launched on the old continent.
