Following the new BMW X1 PHEV that we wrote about last week, the brand have now announced that they will be adding the option of a mild-hybrid powertrain to the latest generation of BMW 5 Series. Set to be available in saloon and touring guise, the mild-hybrid option will join the 5 Series in November.
The 48V mild-hybrid system has been designed to boost both the efficiency and performance of BMW’s new 520d, reducing the 0-62mph sprint whilst also increasing fuel economy by around 10%; meaning it’ll be capable of 68.9mpg combined and low CO2 figures of 108g/km.
The mild-hybrid system is made up of a 48V starter-generator that is connected to a second battery, this harvests power from braking and coasting (even allowing the engine to completely shut-off when coasting).
The stored power in that battery can then be deployed to either increase power or help reduce fuel usage, depending on driving style and/or which driving mode is selected.
Unlike the plug-in hybrid version of the BMW 5 Series, the mild-hybrid option only gains charge from the above methods and, where the plug-in hybrid uses electricity as an alternative to petrol-power, it uses electricity to assist the combustion engine.
Set to become an option in November 2019, BMW say that they’ll offer the mild hybrid technology with the 520d in saloon and touring guise and with either pure rear-wheel drive or xDrive four-wheel drive.
The latest BMW 5 Series range (which can be explored here) is one of the largest evolutions of the much-loved model; introducing both a mild-hybrid and plug-in hybrid variant to the range for the first time. Alongside the additional powertrains, the new 5 Series features revised styling, the introduction of BMW Laserlight and a range of innovative new interior technologies.
As mentioned, the mild-hybrid BMW 5 Series will be appearing in November 2019 and is set to join a BMW model range that is growing evermore electrified. Would you like to learn more about BMW’s BMW i and BMW Plug-in Hybrid ranges? Just take a look below.
