Understanding BMW Efficient Dynamics

If you're familiar with BMW's model range, you'll have seen the term 'Efficient Dynamics' applied to a selection of cars - but what is Efficient Dynamics?

Simply put, Efficient Dynamics it's a strategy BMW is employing to both ensure that its cars are kind to the environment as possible while remaining good to drive.

Understanding BMW Efficient Dynamics

To achieve the goal of environmental sensitivity, an obvious tack is engine efficiency. The current BMW engine range is more efficient than ever, with a mix of latest-generation Euro 6 emissions-compliant diesel and petrol engines, using turbocharging to ensure reliable low-emission operation. Smaller BMW models like the 1-Series and 2-Series use three cylinder petrol and diesel engines for even better fuel efficiency.

The ultimate in low emissions though is electric power, and BMW has the largest range of hybrid and electric vehicles of any manufacturer. The breadth of BMW's electric range should be little surprise - BMW has been working on electric vehicles since the 1602e, used as an official vehicle of the Munich Olympics in 1972. With hybrid models like the i8, 225xe, 330e and X5 xDrive40e alongside the all-electric i3, your choice of ultra low emission vehicles

Efficient engines are only part of the puzzle though. With great attention paid to aerodynamics, cars need less power to push them through the air in the first place, and BMWs are designed to be as aerodynamically efficient as possible. Employing aerodynamic measures like an active rear spoiler, variable front air vents and the Aero Curtain reducing the drag caused by the wheel wells, BMW is able to achieve a low drag coefficient, improving fuel economy and reducing cabin noise.

One of the keys to improving efficiency is reduction of weight - getting a heavy car moving is less fuel efficient. BMW uses aluminium and magnesium alloys in key areas, along with carbon-fibre reinforced plastic (CFRP) composites to keep kerb weights down.

All of these features designed to improve efficiency have a knock-on effect for vehicle dynamics too. Low weight cars are easier to accelerate, brake and turn, while more aerodynamic ones require less power to travel at speed and are more stable at high speeds. The use of turbochargers allows for higher power outputs too.

While there are specific Efficient Dynamics cars in BMW model ranges, the principles of Efficient Dynamics apply to every BMW, to provide you with cars that are as enjoyable to drive as they can be, while remaining as economical as possible.
