UNIQUE DYNAMICS. UNIQUE FUEL EFFICIENCY.

BMW EfficientDynamics in the BMW 4 Series Gran Coupé.

The sportiness of the BMW 4 Series Gran Coupé is always accompanied by outstanding efficiency. This is a result of BMW EfficientDynamics, a comprehensive package of measures and technologies that increase dynamics while, at the same time, reducing emissions. The special aerodynamics catch the eye immediately, but there are also many other technologies working away in the background. And they make their presence felt ,too – in the form of reduced fuel consumption and increased driving pleasure.

ENERGY MANAGEMENT.

The BMW 4 Series Gran Coupé contains a number of BMW EfficientDynamics technologies as standard, including the Automatic Start/Stop function, Brake Energy Regeneration and Electric Power Steering. These technologies combine to guarantee intelligent energy management – and sustainable mobility.

  • Automatic Start/Stop function
  • Brake Energy Regeneration
  • Optimum Shift Indicator
  • Electric Power Steering

AERODYNAMICS.

The entire vehicle design is a testament to the BMW EfficientDynamics philosophy. The optimised, aerodynamic front apron and undercarriage feature innovative improvements that reduce air resistance and fuel consumption.
The front apron is a prominent design feature that embodies the BMW EfficientDynamics philosophy. The integrated Air Curtain channels air through two vertical air inlets and along the front wheel arches. The accelerated air flow creates a kind of “curtain” on the outer side of the wheels. Then there is the Air Breather, which channels the air flow at the front wheels. These innovative technologies reduce turbulence and air resistance, which in turn reduces fuel consumption.
The flat undercarriage cover, which also shields the engine compartment, is an additional detail that greatly improves the car’s aerodynamics. These new trim elements are not only highly advantageous in terms of aerodynamics: they also improve sound insulation and provide greater protection from rust.

ECO PRO MODE.

The ECO PRO Mode helps drivers reduce their fuel consumption by up to 20 percent, depending on their driving style – according to an internal BMW fuel consumption study. Another five percent can be saved by using the coasting function (only with the 8-speed Steptronic transmission), the Route-Ahead Assistant (only with Navigation System Professional) or ECO PRO Route (only with Navigation System Professional or Business).
ECO PRO Route shows the most efficient route based on the traffic situation, driving style and road conditions. The on-board computer displays the percentage of fuel that can be saved by driving along the route selected by ECO PRO Route.

LIGHTWEIGHT CONSTRUCTION.

Thanks to lightweight construction, every gram shed from the vehicle’s weight increases driving pleasure. With less weight to move, less energy is required. BMW has applied this knowledge to vehicle construction since the 1930s, constantly improving along the way. The questions that the BMW engineers constantly confront are: Where does it make sense to reduce weight? And where would it be impractical? The result: intelligent lightweight construction. This involves the use of ultra-light materials such as magnesium, aluminium and CFRP (carbon fibre-reinforced plastic) in carefully targeted areas of the vehicle.

BMW TWINPOWER TURBO TECHNOLOGY.

In petrol engines, BMW TwinPower Turbo technology combines a TwinScroll turbocharger with Valvetronic, including Double-VANOS and High Precision Injection. In the diesel engines, specially optimised turbocharger technologies are combined with the latest generation CommonRail direct injection and variable turbine geometry. BMW TwinPower Turbo significantly reduces the fuel consumption of BMW petrol and diesel engines – while at the same time boosting power output across a wide range of engine speeds.
