BMW has announced a slew of model update measures for autumn 2019, with the first being the adoption of mild hybrid technology for the G30 5 Series. According to the German carmaker, this provides “extra sprinting power and efficiency.”

Available for the 520d models (Sedan and Touring; with or without xDrive) from November this year, the system features a 48-volt starter-generator and a second battery that significantly enhances energy recuperation even more when braking.

This can then be used to assist the engine, allowing it to operate within an efficiency-optimised load range as frequently as possible. There’s also an overboost function, which provides a bit of extra power when accelerating under full throttle.

Another benefit of the mild hybrid system is a smoother operation of the start-stop function, as well as the ability to completely shut off the engine in coasting mode, rather than just disconnecting it from the drivetrain. BMW says with the mild hybrid system in play, the 190 PS (188 hp) engine has a lower fuel consumption by up to 0.3 litres per 100 km.

Aside from the mild hybrid system, the M550d xDrive Sedan and Touring now come with BMW Laserlight, which which increases high-beam range to a maximum of 650 metres for better visibility.

Meanwhile, the 330e Sedan, 530e Sedan and 530e xDrive Sedan will be offered with an optional trailer coupling with an electrically pivoting hitch ball, which has a maximum trailer load of 750 kg.

Moving on, the range-topping M135i xDrive gains an optional M Performance package for greater visual impact. The package includes 18?inch M light-alloy wheels in a Y-spoke design and the deletion of the storage package. The latter helps shave 10 kg and 0.1 seconds from the car’s zero to 100 km/h time to 4.7 seconds. Also included are exterior mirror caps, exhaust tailpipes and kidney grille all finished in black.

The 8 Series Gran Coupe’s options list will also be expanded to include an M Carbon roof, along with interior trim strips in the same material. In the SUV camp, the X5, X6 and X7 will gain more BMW Individual items, with the X5 also receiving an optional Adaptive M suspension Professional system (M Sport differential and Integral Active Steering). Lane Change Assistant is also added to the Driving Assistant Professional system of the X5 and X6.

BMW has also updated the Driving Assistant Professional system to include a 3D visualisation of the area around the car, while the functionality of the BMW Intelligent Personal Assistant now includes a separate iDrive menu and individual configurability.
