大众为高尔夫掀背车开发弱混动系统已经不是秘密，现在更多细节被媒体曝光。据英国媒体报道，大众正在为高尔夫开发两个不同的混动系统。其中高尔夫MHEV是经典的弱混动车型，该车搭载一台1.5升TSI涡轮增压引擎，它利用皮带传动起动发电机和48伏锂电池组（电池尺寸与普通的12伏电池一样）。在此类布局下，汽油引擎搭配全新七速DSG双离合器自动变速箱。而高尔夫MHEV Plus搭载了一台额外增加的26千瓦/35马力电机用于驱动前轮。而第二台电机安装在后轴，让车辆具备分时全驱能力。不过这并非标准的全驱系统，因为电机输送给后轴的扭矩比传统的内燃机引擎更小，不过，工程人员认为，这样的布局对于提升车辆在转向时的稳定性是一个很好的解决方案，同时有助于降低转向不足。

VW Working On Two Golf Mild Hybrid Versions

It’s not a secret that Volkswagen is developing a mild hybrid system for the Golf hatchback and we now have more details to share about the project. Autocar had the chance to drive prototypes of the Golf MHEV and their report reveals the German company is actually working on two separate sytems.

The Golf MHEV is a classic mild hybrid vehicle, powered by a 1.5-liter turbocharged TSI gasoline engine, which uses a belt-integrated starter generator (BISG) and 48V lithium ion battery with the size of a conventional 12-volt battery. In this layout, the gas motor is mated to an all-new seven-speed DSG dual-clutch automatic gearbox. The Golf MHEV Plus is a much more interesting development, as it also uses an additional 35-horsepower (26-kilowatt) electric motor, which powers the front wheels. Interestingly, this second motor can also be installed on the rear axle, giving the car part-time all-wheel drive. It’s not a typical AWD system, because the torque the electric motor delivers to the rear axle is less than that of an ICE-powered system, but the engineers believe this is a good solution to improve the stability in corners and to reduce understeer.
