The next-generation Volkswagen Golf is coming in 2020 and details regarding the 48V mild hybrid system have been revealed. See details below…

In an effort to improve efficiency and reduce emissions, the Golf 8 will offer a mild Hybrid Electric Vehicle (mHEV) derivatives with 48V technology. According to Volkswagen, 48V technology will be initially offered in conjunction with both the 1.0-litre and 1.5-litre (EA211 evo) engines and DSG gearbox. The system will then later be offered on other derivatives and models.

Where a Plug-in Hybrid (PHEV) gains battery charge via a plug, the mHEV is equipped with a 48V belt starter generator which, like an electric motor, supports the combustion engine in acceleration, for example. During deceleration, the generator converts kinetic energy that would otherwise be lost and charges the 48V Lithium-ion battery located under the passenger seat. This stored electrical energy can then be used to boost the Golf’s acceleration but more importantly, contributes to up to 0.4 L/100km in fuel savings, depending on the driving style.

The mild hybrid system is able to shut the engine off when the driver lifts off the accelerator and comes back to life when the accelerator is applied again. Volkswagen says that the engine is switched on and off ‘without delay’ or loss of comfort and with very little vibration.

As Volkswagen is readying its electric car family which will go on sale in 2020 (ID.3, ID.Crozz, ID, Vizzion, ID.Roomzz) with a projected 40% electric new car share in 2030, combustion engines will still play an integral role in the foreseeable future and mild hybrid technology is expected to become more widespread in an effort to reduce emissions and improve efficiency.
