Volkswagen’s next-generation Golf will usher in a brand new era of mild hybrid powertrains when This specific can be revealed towards the end of next year
The next Volkswagen Golf, which can be due to be revealed late next year, will bring with This specific the first solid evidence of Volkswagen’s brand new electrification strategy, ushering in an era of brand new super-frugal mild hybrid powertrains.
Insiders predict the brand new Golf will feature a brand new 48V petrol hybrid system as its main powertrain option – a strategy which could be particularly effective in the US market, where VW’s ‘clean diesel’ aspirations look dead from the water from the wake of its emissions scandal.
The initial overhaul of the MQB architecture was well under way before the diesel emissions scandal hit the company. The aim was to reduce the expense of an architecture of which many analysts (in addition to also rival car makers) believe has been over-engineered for the cost points of the vehicles This specific underpins.
Targeting a ‘real-world’ 60mpg, the brand new mild hybrid powertrain can be thought to be based on the company’s brand new turbocharged 1.0-litre three-cylinder petrol engine, with the addition of an electrically driven supercharger in addition to also a combined starter motor/generator. A low-cost lead-acid battery can be used to store recovered energy, such as when the vehicle can be braking.
Unlike a conventional hybrid transmission, which uses a full-size electric motor, these 48V mild hybrids provide assistance to the petrol engine via the oversized starter motor/generator. The belt of which connects the starter motor to the engine’s crank pulley can be also used to assist the engine when extra power in addition to also torque are needed. The process can be reversed to allow the engine’s crank pulley to turn the starter motor/generator when the vehicle can be slowing down.
This specific recovered energy can be not used just to assist the engine. This specific can be also used to power a tiny supercharger of which’s driven by an electric motor. By powering the blower electrically, rather than relying on engine in addition to also exhaust gas speed to drive This specific, This specific can boost the engine’s performance through very low revs.
These two forms of electrical assistance allow the engine of a 48V hybrid to be significantly downsized, enabling a 1.0-litre three-pot Golf to offer brisk performance in addition to also impressive economy.
Insiders say the brand new 48V hybrid system should be competitive on cost which has a modern EU6-rated diesel engine, because This specific doesn’t use a full-size electric motor or an expensive lithium ion battery. This specific can be particularly relevant at This specific point of which VW has announced of which expensive urea injection systems are likely to be fitted to Golf-class diesel designs.
several automotive in addition to also component companies are meeting next month in Düsseldorf to rubber stamp the final industry-wide technical specs for these 48V hybrids.
