Lower emissions,
better fuel economy.
is the next step in a philosophy that BMW has been recycling energy that would otherwise be wasted.
developing for several years, aimed at increasing engine power while reducing both fuel consumption and emissions.
To achieve these goals, BMW has been pioneering the use of more lightweight materials to achieve significant weight reductions. Lower weight creates improved power to weight ratios, leading to lower fuel consumption. At the same time, BMW has also been developing advanced engine technologies like Twin Turbo and High-precision direct injection, which use fuel more intelligently to deliver increased driving pleasure and performance, as well as lower emissions.
As well as benefiting from increased engine power and performance, drivers will notice the advantages of
EfficientDynamics in lower BIK tax liabilities and reduced fuel costs.
Three pillars of innovation.
The integrated series of new innovations that
EfficientDynamics encompasses includes the development of existing technologies, intelligent energy management and the use of selected hybrid technologies. In the longer term, this concept will be extended to include the widespread adoption
of hydrogen power, as seen in the unique new
BMW Hydrogen 7.

Intelligent Energy
Management Systems.
The five new technologies central to the EfficientDynamics programme are:
Auto Start-Stop.
The engine automatically stops whenever the car comes to rest and the gear is disengaged – for example, at traffic lights – and restarts the second the clutch is depressed, saving fuel and reducing emissions.
Intelligent Alternator Control.
Disengages the alternator when the battery is fully charged, and only engages again when the battery needs charging.
This decreases engine drag, reducing fuel consumption
and emissions at the same time.
Brake Energy Regeneration.
better fuel economy. When the car’s brakes are applied or when coasting downhill, this system automatically engages
the alternator to charge the battery to full power, recycling energy that would otherwise be wasted.
Electric Power Steering.
Makes the car easier to handle at slow speeds. Removing the existing hydraulic system saves weight and removes the need for a pump to be driven from the engine, reducing fuel consumption.
Optimum Gear Shift Indicator.
A small indicator on the car’s dashboard display shows the optimum gear for any driving situation, giving drivers the ability to adopt a more fuel-efficient driving style.

EfficientDynamics and the new
BMW 1 Series.
As the first BMW model range to fully adopt the principles of EfficientDynamics, the new BMW 1 Series offers significant benefits for drivers. For example, the attractive new BMW 118d model returns an exceptional 60.1mpg on the combined cycle, giving the car a BIK tax rating of just 18%, while power has increased by 17.2%.
Another popular choice, the BMW 118i has achieved a remarkable 20.5% reduction in CO2 emissions to just 140g/km. This gives it a BIK rating of just 15%, which reduces vehicle excise duty by £35 and can save higher-rate drivers up to £505 a year in tax. |
