BMW EfficientDynamics: All You Need For Megacity Driving

Our interest in BMW i models and respect towards company technologies is endless. EfficientDynamics is one of the BMW concepts we absolutely like at Bmwiclub.
BMW EfficientDynamics is incorporated in every BMW i car. Last time we told about innovative BMW eDrive concept, which is one of the core technologies in EfficientDynamics strategy. Now let’s understand the concept behind BMW EfficientDynamics and its major technologies.

Understanding EfficientDynamics Concept
EfficientDynamics is a strategy developed at BMW to reduce car fuel consumption and toxic emissions while increasing dynamics. It is a mix of electromobility systems, efficiency measures and high-tech functions coupled towards improving car energy management, construction, aerodynamics, combustion engines and electric motors. Increased driving performance and reduced power consumption – this is EfficientDynamics from BMW.
Especially clearly the efficient driving concept from BMW is manifested in its electric cars, the i3 and i8, intended for driving in mega cities where car dynamism, lightweight construction, low CO2 emission and sustainable mobility are most needed. Urban driving and vibrant city lifestyle requires from the car optimal combination of efficiency and dynamics, just what the BMW concept is all about.

Combustion engines
BMW EfficientDynamics covers the family of latest generation petrol and diesel engines: BMW 3- and 4-cylinder petrol engines and the award-winning BMW TwinPower Turbo inline 6-cylinder petrol engine, each one delivering outstanding dynamics, being low on emissions and fuel consumption.
In the i8 model, a 3-cylinder, 1.5-liter TwinPower turbo gasoline engine is paired with eDrive technology to combine all the benefits of an electric motor and a gasoline engine, delivering dynamic yet economical driving performance.

Electric drivetrain
BMW electric drivetrain is build up on the concept of “more energy, less fuel”. This concept is embodied in BMW eDrive technology gathering together the electric motor, the high-performance lithium-ion battery and intelligent energy management strategy. BMW cars driven on electric mode with a fully charged battery show breathtaking speeds and have the range enough to cover most daily destinations. BMW EfficientDynamics mixed with eDrive create smooth electric driving, which is free from noise and local emissions. The electric motor and battery are all manufactured in-house.

Lightweight construction
The lower the car weight, the faster it accelerates, the more maneuverable and efficient it is. The essential components of BMW EfficientDynamics are improved aerodynamics and lightweight materials, used to reduce the fuel consumption level and car emissions. Lightweight construction is vital for an electric car. It allows for dynamic performance, maneuverability and minimum power consumption. To additionally reduce car weight, the BMW uses innovative material at car building – the carbon. It is 50% lighter than the steel and 30% lighter than the aluminum, but it is as strong and safe. BMW i models are the first cars, featuring this high-tech material in the construction.

Aerodynamics
Improved aerodynamics is one more component of BMW EfficientDynamics concept. Many car design elements are optimized in terms of aerodynamics to ensure car efficiency and optimized drag coefficient. An aerodynamic car from BMW combines such measures as the automatic air vents, the active rear spoiler, the Air Curtain in the front apron, the Air Breather that channels the air on the front wheels, and more components for airstream control, which in turn lowers fuel consumption and CO2 emissions. The aerodynamics of the BMW EfficientDynamics concept cars is also enhanced with the aerodynamic, optimized wheel rims.

Energy-saving functions
BMW EfficientDynamics technologies include energy-saving functions such as the Brake Energy Regeneration, Automatic Start/Stop, Brake Energy Regeneration, Electric Power Steering, Gear Shift Indicator. Minimum fuel consumption and low emissions are the core tasks behind each and every energy-saving technology in the BMW car.
Our opinion is that the regeneration of brake energy is one of most effective technologies used by BMW for energy management. The idea is that the braking energy converts into electrical power to charge the battery. Thus, less effort is required from the engine to charge the battery, which in turn leads to decreased fuel consumption and low emissions.

Efficiency & Dynamics – All We Need For Megacity Driving
It is obvious for us that each technology of BMW EfficientDynamics is well-thought-out and helps the driver to adapt the car to driving situation while at the same time saving energy and driving more efficiently. Although BMW EfficientDynamics is currently the part of every BMW car, the BMW i3 and i8 are the perfect example of company’s EfficientDynamics concept. Electric cars from BMW i are an exclusive combination of two seemingly conflicting properties, the efficiency and the dynamics.
