BMW is making its EfficientDynamics brand have a bigger role than before. Earlier it was just a word to describe a set of fuel saving technologies such as Brake Energy Regeneration and Auto Start-Stop, but now it’s being used as a suffix for cars that are particularly ‘green’. Other car manufacturers also have similiar brands such as Volkswagen’s use of BlueMotion.
The new BMW 320d EfficientDynamics has CO2 emissions of 109g/km and a combined consumption figure of 68.9mpg, which translates to 24.4 km per litre of diesel. The 2.0 litre engine puts out 163hp at 3,500rpm upt o 4,200rpm and 360Nm of torque spread between 1,750rpm to 3,000rpm.
Modification over a regular non-EfficientDynamics 320d include a longer final drive, lowered suspension for better aerodynamics, and special aerodynamics alloy wheels with Michelin EnergySaver tyres. The usual set of EfficientDynamics features are also there – Auto Start Stop, Brake Energy Regeneration and Electric Power Steering.
There have also been some modifications to the engine. A dual mass flywheel with springs and new Centrifugal Pendulum Absorbers is fitted between the engine and transmission. The whole point of these modifications that make the engine ‘smoother’ is to allow the diesel engine to spin more smoothly at the lower RPMs that the new final drive provides.
We might see BMWs like this car and the 118d in Malaysia if the new Euro 2M diesel that is supposed to be introduced in September this year is deemed good enough by the car company’s homologation engineers.
