What to expect from BMW EfficientDynamics…
One of the key reasons people choose to drive a BMW is because of the cutting-edge technologies. They reduce fuel consumption, reduce CO2 emissions, yet at the same time increase driving dynamics, and therefore pleasure.
BMW EfficientDynamics is a comprehensive range of innovative technologies that have helped to reduce the emissions across the entire BMW fleet by 30%, a contributing factor in BMW gaining multiple awards for its sustainability strategy. Yet BMW are still looking for further improvements. BMW is aiming to reduce CO2 emissions a further 25% by 2020, proving to the world that it is possible to act for the benefit of the environment without sacrificing pure driving pleasure.
Over 2 million BMWs have already been equipped with EfficientDynamics technologies - EfficientDynamics feature in every new BMW as standard - and all new models will continue to benefit from this technology in the future. Outlined below is an overview of each of the key technologies that form part of BMW EfficientDynamics.
Brake Energy Regeneration, Power Steering, Resistance Tyres and the ECO PRO Mode are the types of innovative energy efficiency technologies that help to reduce fuel consumption in a BMW.
Brake Energy Regeneration: Slowing down has never been so good for fuel consumption! Whenever you apply the brake or take your foot off the accelerator the energy is used to recharge the battery. The result is less demand on your engine, reduced fuel use, and lower emissions
Electric Power Steering: By using an electric motor to assist the steering, the system is not only lighter in weight than conventional hydraulic power steering, but it is not drawing valuable engine power and using fuel.
ECO-PRO Mode: An intelligent system that helps you use less fuel. It tells you when you are accelerating too aggressively, limits air con according to energy-optimised settings, and shifts transmission faster in higher gears for added energy efficiency. It can help reduce fuel consumption by up to 20%.
Reduced Rolling Resistance Tyres: During driving, the tyres are constantly flexing, which uses both fuel and energy. Special heat-resistant, anti-distortion materials used in Reduced Rolling Resistance Tyres reduce flexing resulting in lower emissions and improved fuel economy.

BMW’s TwinPower Turbo engine significantly reduces the amount of fuel used in both petrol and diesel engines, yet at the same time provides improved power over a range of speeds. A true example of an eco-friendly engine that does not compromise on performance.
Petrol Engines: A TwinScroll turbocharger with VALVETRONIC, Double common-rail direct injection and Variable Turbine Geometry unite to deliver a dynamic power build-up and impressive efficiency. This technology is regarded worldwide as a benchmark for performance, whilst being more economical and eco-conscious than BMW petrol engines that have gone before.
Diesel Engines: A BMW TwinPower Turbo diesel engine combines a common-rail direct injection, a turbocharger, and Variable Vane Geometry to produce an impressively smooth drive whilst delivering reduced fuel consumption and emissions. The increased efficiency and dynamics is the embodiment of the BMW EfficientDynamics ethos.
Precision engineering yields optimised performance. BMW EfficientDynamics has been designed to ensure that everything happens at precisely the right time. When energy isn’t being wasted on an idle engine or high revs fuel efficiency is maximised and performance enhanced.
Auto Start Stop Function: 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.
Optimum Gear Shift Indicator: A small visual display on the car’s instrument cluster shows the optimum gear for any driving situation. This gives the driver the opportunity to adopt a more fuel-efficient driving style.
8 Speed Transmission: Closely spaced gear ratios make shifting gear through to top speed almost unnoticeable. The change is rapid, and when you use the optimum rev range, you also consume less fuel.
Aerodynamics & Lightweight Engineering
The lightweight aluminum body is shaped to channel air, optimise engine performance and reduce drag. Other lightweight metals are also used to bring the weight down further. Improved aerodynamics, less weight and better balance means less fuel is needed and fewer emissions are produced.
Active Aerodynamics: Actively controlled air flaps enable your engine to reach its optimum operating temperature faster, and cool the engine and brakes only when needed. These flaps also improve aerodynamics and reduce drag. The combination of these two effects means increased fuel efficiency.
Lightweight Engineering: The use of advanced lightweight materials, such as thermoplastics, aluminium and magnesium alloy, reduce the overall weight of the vehicle, enhancing driving dynamics and improving fuel economy.
