Hybrid VW golf confirmed

Volkswagen has confirmed an upcoming hybrid model of the eighth-generation Golf. 

Due to be revealed in 2019, the next-generation Golf will be offered with an all-new 48-V mild hybrid option that will work alongside Volkswagen’s current 12-V system.

Volkswagen already offers a completely electric e-Golf, which is currently one of New Zealand’s best selling electric vehicles (EVs), however, the next-generation Golf will be the first time Volkswagen use the new hybrid option, which will be utilised in further models.

Volkswagen will combine a combustion engine with a new 48-V belt-integrated starter generator and a 48-V battery. The mild hybrid system will enable the new Golf to ‘coast’ while the combustion engine is completely switched off, saving up to 0.3 litres of fuel over 100 kilometres while promising improved dynamics and convenience with an “electric boost.”

“Electrifying conventional drives will enable us to further reduce consumption and emissions while also increasing dynamics and convenience”, says Dr Frank Welsch, Member of the Board of Management for Volkswagen Passenger Cars with responsibility for Technical Development.

Welsch continues: “We are starting this extensive electrification campaign with Volkswagen’s best-selling vehicle to date – the Golf. Our newly developed, cost-effective 48-V mild hybrid will pave the way for introducing this type of technology to the mainstream”.

Volkswagen states that the 48-V system enables a considerably higher amount of energy to be saved than the 12-V system, e.g. via recuperation when the vehicle brakes. This high level of voltage enables a number of operations, including the actuation of the 48-V belt-integrated starter generator.

The generator performs the role of alternator and starter. At the same time, it functions as a small, lightweight electric motor that immediately increases drive torque upon start-up by means of an electric boost. The power of the generator is transferred via a belt. The generator also starts the combustion engine – which is switched off as much as possible while the vehicle is moving.

Welsch continues: “The basic interaction of different energy sources – electricity, petrol, diesel and natural gas – represents a paradigm shift at Volkswagen. For the first time, the company will simultaneously offer product lines such as the Golf with conventional, electrically assisted drives as well as product lines such as the I.D. with purely electrical drives in the future.”
