在大众宣布计划于明年6月推出第八代高尔夫之后，近日又宣布正在开发全新轻混系统，它采用48伏技术，将首次应用于下一代高尔夫以提升燃油经济性。虽然大众并未透露太多细节，但明确表示，燃油引擎将搭配48伏皮带驱动起动/发电机和48伏电池。轻混系统可以让车辆百公里油耗降低0.3升。在驾驶员松开油门踏板后，离合器分离，引擎停转。不过，这种情况只在某种情况下发生，比如在车辆下坡行驶时。至于轻混系统，可以让车辆在起步时获得更高扭矩。发电机产生的动力通过皮带传递，而内燃机引擎实际是依靠发电机发动的。系统受益于制动能量回收系统，因此可以在车辆降速时为电池充电。下一代高尔夫将于明年在欧洲上市。

 

Volkswagen Golf 8 Mild Hybrid Officially Announced

After announcing plans to kick off production of the eighth-generation Golf in June 2019, Volkswagen has now shared a little bit more details about the next iteration of its best-selling model. The VW Group’s core brand is working on an all-new mild hybrid system with 48-volt technology and it will be first implemented in the next Golf to provide improved fuel economy.

 

For the time being, VW isn’t going into too many details, but it does say the combustion engine will be teamed up with a 48-volt belt-integrated starter generation and a 48-volt battery. The mild hybrid system will allow the Golf 8 to coast with the ICE turned off entirely and save up to 0.3 liters / 100 km. Once the driver releases the accelerator pedal, the clutch is disengaged and the engine shuts off, but this happens only in certain conditions like when going down a slope.

 

Getting back to the mild hybrid system, VW mentions it will give the new Golf an electric boost upon startup by providing extra torque once the driver fires up the engine. The generator’s power is channeled through a belt and the combustion engine is actually turned on by that generator.

 

The system will benefit from an energy recovery system, so it will be possible to charge the battery on the go while the car is slowing down.

 

The next-gen Golf will be going on sale in Europe next year when VW is also going to introduce its first I.D. production model, an all-electric compact hatchback.
