宝马在2014集团创新日发布了3系插电混动原型车。该车基于即将推出的3系改款车，因此车辆的头部和尾部进行了伪装，不过该车最大变化还是在内部。这款车搭载一台2.0升四缸涡轮增压汽油引擎和一台电机，综合输出功率180千瓦/245马力，扭矩400牛米，达到3系六缸车水平。与动力系统搭配的是一台八速Steptronic变速器，车辆百公里油耗仅为2升，每公里二氧化碳排放量50克。在纯电动模式下最长可行驶35公里，最高时速120公里。这款原型车配备的锂电池组位于储物箱地板下，可以使用家用插座充电。该车还在中控台设置了驾驶体验控制（Driving Experience Control）切换开关，可以让驾驶员在COMFORT, SPORT 或 ECO PRO（舒适、运动或省油）模式之间进行转换，根据不同的模式，悬挂、变速箱和混动运行等设置也不同。

 

BMW 3-Series plug-in hybrid prototype revealed

BMW has unveiled a 3-Series plug-in hybrid prototype during the Group Innovation Days 2014.

 

It's based on the upcoming facelift which is why the prototype depicted here wears camouflage on the front and rear fascias but the most significant changes are underneath the skin. Power comes from a four-cylinder 2.0-liter turbocharged gasoline engine working with an electric motor which according to BMW offer the prototype the same level of performances as a six-cylinder 3-Series.

 

The combined output stands at 245 HP (180 kW) and 400 Nm (295 lb-ft) channeled to the wheels via an updated eight-speed Steptronic transmission granting a fuel consumption of only 2 liters / 100 km (140 mpg UK or 117 mpg US) with corresponding CO2 emissions of 50 g/km. It can be driven in electric mode for up to 22 miles (35 km) during which it's able to hit a top speed of 74.5 mph (120 km/h).

 

The BMW 3-Series plug-in hybrid prototype features a lithium-ion battery pack installed underneath the load compartment which can be charged from a regular household socket. The vehicle also boasts a Driving Experience Control switch installed on the center console from where the driver can select from COMFORT, SPORT or ECO PRO modes that alter the settings of the suspension, gearbox and the hybrid operating strategy.
