BMW is making further advances in its push to boost the driving pleasure and efficiency of its current model range with the introduction of state-of-the-art mild-hybrid technology in autumn 2019. Fitting a 48V starter-generator in the BMW 5 Series for the first time has the additional benefit of increasing power output and reducing fuel consumption and emissions. Meanwhile, the BMW 330e Sedan (fuel consumption combined: 1.9 – 1.6 l/100 km [148.7 – 176.6 mpg imp]; electric power consumption combined: 15.4 – 14.8 kWh/100 km; CO2 emissions combined: 43 – 37 g/km), BMW 530e Sedan (fuel consumption combined: 1.8 – 1.6 l/100 km [156.9 – 176.6 mpg imp]; electric power consumption combined: 14.5 – 13.6 kWh/100 km; CO2 emissions combined: 41 – 36 g/km) and BMW 530e xDrive Sedan (fuel consumption combined: 2.2 – 2.0 l/100 km [128.4 – 141.2 mpg imp]; electric power consumption combined: 15.4 – 14.1 kWh/100 km; CO2 emissions combined: 49 – 46 g/km) plug-in hybrid models will offer even greater versatility and everyday practicality from November 2019 when a trailer coupling joins the options list.
New optional extras designed to further enhance sporting prowess and driving comfort will also be made available for numerous other models from autumn 2019. Some of the most tempting additions to the options lists include the M Performance package for the BMW M135i xDrive (fuel consumption combined: 7.1 – 6.8 l/100 km [39.8 – 41.5 mpg imp]; CO2 emissions combined: 162 – 155 g/km), BMW Laserlight for the BMW 5 Series and the M Carbon roof for the new BMW 8 Series Gran Coupe. Finally, new exterior and interior options open up a wealth of possibilities for individualising the new BMW X5, new BMW X6 and new BMW X7.
BMW 5 Series: mild-hybrid technology for extra sprinting power and efficiency
In autumn 2019, BMW will present another element in its powertrain electrification strategy to accompany the ongoing expansion of its plug-in hybrid line-up. Mild-hybrid technology will make its debut in the BMW 5 Series, where it will help to both lighten the combustion engine’s workload and boost its power, meaning not just superior efficiency but sharper performance. Fitting an extremely powerful 48V starter-generator and a second battery significantly enhances the functionality of Brake Energy Regeneration by enabling the energy recuperated when braking or on the overrun to be harnessed not just for powering electrical vehicle functions, but for generating additional drive power. For this, the 48V starter-generator acts likes an electric drive unit that assists the engine, allowing the latter to operate within an efficiency-optimised load range as frequently as possible. An electric overboost function, meanwhile, injects an extra dose of dynamism when accelerating under full throttle.
The 48V starter-generator has the additional benefit of allowing the engine to be switched off with remarkably little vibration and restarted more smoothly when using the Auto Start Stop function. This also makes it possible to completely shut off the engine in coasting mode, rather than just disconnecting it from the drivetrain. As of November 2019, mild-hybrid technology will be fitted as standard on the BMW 520d Sedan (fuel consumption combined: 4.1 – 4.3 l/100 km; CO2 emissions combined: 108 –112 g/km), BMW 520d xDrive Sedan (fuel consumption combined: 4.5 – 4.7 l/100 km; CO2 emissions combined: 117 – 123 g/km), BMW 520d Touring (fuel consumption combined: 4.3 – 4.5 l/100 km; CO2 emissions combined: 114 – 118 g/km) and BMW 520d xDrive Touring (fuel consumption combined: 4.7 – 4.9 l/100 km; CO2 emissions combined: 124 – 128 g/km). The fuel consumption figures of the 140 kW/190 hp four-cylinder diesel engine that powers this quartet of models will be cut by up to 0.3 litres per 100 kilometres as a result.
The enhancements to the BMW 5 Series range also include the introduction of BMW Laserlight on further model variants. This lighting technology – which increases high-beam range to a maximum 650 metres – will be added to the wealth of innovations aboard both the BMW M550d xDrive Sedan and BMW M550d xDrive Touring from November 2019.
