BMW has revealed details of range-wide updates for its cars in Spring 2020.

The main news consists of the further roll out of mild-hybrid technology across the line-up. This is to “contribute towards a further reduction of consumption levels and the optimisation of the emission performance of current models”, BMW says.

Following the 520d – which gained the fuel-saving feature in Autumn 2019 – BMW’s 320d, X3 xDrive20d and X4 xDrive20d will also get mild-hybrid tech.

The tech is comprised of a 48-volt starter generator – which delivers an additional power output of 11bhp – and a second battery.

An over-boost function can be used to aid acceleration from a standstill, as well as to help support the combustion engine.

In addition to this, the German firm claim 33 of its models will already comply with the Euro 6d emission standard in Spring 2020, despite it not being obligatory until 2021.

Apart from the mild-hybrid tech, BMW has announced additional interior design options for its X5 and X6 SUVs.

From April, the perforated leather Vernasca trim in the colour combination Canberra Beige/Black will be available for the three models.

The 7 Series luxury saloon, 8 Series grand tourer and M8 Competition Coupe performance GT will receive an automatic soft-close function for the doors “in the future” as well.
