BMW EfficientDynamics Guide
Posted on 9th Jun 2008
BMW EfficientDynamics is a range of related technologies that reduce fuel consumption and emissions while simultaneously improving performance. In achieving this, BMW is helping to shape the future of driving by pioneering the ultra efficient engines of tomorrow.
Innovative new technologies are designed to maximise the efficiency of the internal-combustion engine and deliver significant environmental and cost savings to customers. Here Williams will show you the efforts made to produce the most efficient and dynamic BMW’s to date.
Active Aerodynamics
Actively controlled air flaps regulate air flow to the engine and braking systems. By opening and closing these flaps, the engine is able to reach its operating temperature quicker, whilst vehicle drag is also reduced -helping the car move through the air more easily and reducing fuel consumption and emissions.
Auto Start-Stop
Stops the engine automatically whenever the car comes to rest and is taken out of gear - for example, at traffic lights - and restarts the second the clutch pedal is depressed, saving fuel and reducing emissions.
Electric Power Steering
By using an electric motor to assist the steering, the system is not only lighter in weight than a conventional hydraulic power steering, thereby reducing fuel consumption and emissions - but assistance can also be varied to aid the driver at lower speeds.
Optimum Shift Indicator
A small visual display on the car’s dashboard shows the optimum gear for any driving situation. This gives drivers the opportunity to adopt a more fuel efficient driving style.
Intelligent Alternator Control/Brake Energy Regeneration
Intelligent Alternator Control monitors battery condition, engaging the alternator as and when the battery requires recharging. This reduces the demands on the engine, reducing fuel consumption and emissions. In addition, when the car’s brakes are applied or when coasting downhill, this system automatically engages the alternator to charge the battery, recycling energy that would otherwise be wasted.
Lightweight Engineering
The overall weight of the vehicle is reduced through the use of lightweight materials such as thermoplastic, aluminium and magnesium alloy. The results are enhanced driving dynamics and improvements in both fuel economy and weight distribution.
Low Friction Fluids
Reducing fluid friction in an engine helps minimise wasted energy and, consequently, fuel consumption and emissions. BMW uses low friction transmission fluid, engine oil and final drive fluid to help the vehicle run more smoothly and efficiently.
Reduced Rolling Resistance Tyres
Special heat resistant, anti-distortion materials are used in the tread and sidewalls of the tyre, to reduce tyre flexing in all driving situations, thereby helping to lower emissions and improve fuel efficiency.
