BMW reorganizes its range and raises its bet on Mild-Hybrids

Diesel models gain electric technology for smoother starts and improved economy; the new Serie 1BMW gains the new 120d engine option. A range of BMW diesel models will be equipped with mild hybrid power systems as standard from spring, promising better fuel economy and reduced emissions.

All 320d models, including the xDrive four-wheel-drive variants, the BMW X3 xDrive20d and the BMW X4 xDrive20d, powered by the same 2.0-litre turbocharged diesel engine, will receive a 48V starter-generator and an additional battery for a 13 CV power boost, regenerative braking capabilities and an enhanced coasting function.

The small generator is said to improve acceleration from a standstill and can be used at speed to reduce fuel consumption. It will also allow smoother restarts, via the start-stop system, in traffic and at junctions.

Regenerative deceleration works by disconnecting the combustion engine at speeds below 20 km/h, recovering kinetic energy when the car coasts to a stop. Likewise, at speeds of up to 160 km/h, the coasting function now disconnects the diesel engine instead of leaving it idling.

BMW claims the system, as well as offering fiscal and environmental benefits, “improves both efficiency and dynamics” of the updated models.

Mild hybridisation, the new bet of the Bavarian brand

Alongside the rollout of mild hybrid technology, BMW has introduced a new diesel-engined version of its hatchback 1 Series. The 120d uses a 2.0-litre turbocharged four-cylinder engine producing 187 CV to accelerate from 0 to 100 km/h in 7.3 seconds, and reaches a top speed of 231 km/h. Power is sent to the front wheels via an eight-speed automatic gearbox.

The petrol-powered 318i has also been updated, swapping its three-cylinder engine for a 2.0-litre four-cylinder unit that delivers 231 km/h and 249 Nm of torque. The 3 Series saloon from BMW; the 318i will now accelerate from 0-100 km/h in 8.4 seconds and reach a top speed of 223 km/h.

WLTP fuel consumption and CO2 emission figures, specifications and prices will be confirmed closer to the arrival of the new models in March. Elsewhere in the range, the Bavarian brand’s flagship 7 Series and the German 8 Series Coupé have received additional standard equipment, including a soft-close door feature.
