The efficiency of the BMW 3 Series Touring.

How to avoid excessive fuel consumption: with intelligent, fuel-saving measures from BMW EfficientDynamics.

The design of the BMW 3 Series Touring is systematically geared towards the BMW EfficientDynamics philosophy. The aerodynamically optimized front bumper and the underbody, in particular, impress with their innovative new features that reduce drag and fuel consumption. Embodying the BMW EfficientDynamics philosophy in a visible design feature is the front bumper of the BMW 3 Series Touring. The integrated Air Curtain guides the airstream along the front wheel housings via two vertical inlets. Once accelerated, the stream of air then forms a “curtain” around the outer sides of the wheels. This curtain reduces turbulence and drag, thus lowering fuel consumption. The smooth underbody lining and the engine compartment screening are further details that enable a significant enhancement in aerodynamics. Yet the new lining features not only bring a considerable gain in terms of aerodynamics, they also provide improved acoustic insulation and increased corrosion protection as practical benefits.


Red lights, traffic jams, road works – in everyday driving situations there are many instances where the engine is idling, unnecessarily burning fuel. The Auto Start Stop function in the BMW 3 Series Touring switches off the engine when the vehicle stops temporarily and thus avoids unnecessary fuel consumption. The Auto Start Stop function in the BMW 3 Series Touring switches off the engine as soon as the vehicle is not moving. However, intelligent electronics only deactivate the engine when no energy is needed by other loads and there is no adverse effect on your safety and travelling comfort. So, for example, the engine remains active until the optimum running temperature has been attained or until the interior climate has reached the desired range. Depending on the type of transmission in the vehicle, when the engine has been switched off by the Auto Start Stop function, either releasing the brake or engaging the clutch will cause it to start up again in a fraction of a second. The result is less fuel consumption and fewer emissions.


As soon as you switch to the ECO PRO Mode, everything is geared towards greater efficiency and depending on your individual driving style, this results in a reduction in fuel consumption of up to 20 per cent (according to an internal BMW fuel consumption study). This mode optimizes accelerator and transmission response as well as shift points, and intelligently adapts the heating/air conditioning strategy. The Control Display shows you which EfficientDynamics technologies are currently lowering your fuel consumption. You’ll also receive ECO PRO tips that relate to your current driving situation to help you boost efficiency even further. A further 5% can be saved by using the additional coasting function (only with Steptronic transmission), preview assistant and ECO PRO Route (both only with Navigation system Professional) and the Active Cruise Control in the ECO PRO Mode.

  • Coasting function.

    The coasting function is a highlight of the ECO PRO Mode: if within a speed range of 50–160 km/h the driver takes his foot off the accelerator and does not brake, the system disconnects the engine and the car coasts – i.e. rolls without engine power.

  • Preview assistant.

    The preview assistant, in conjunction with Navigation System Professional, is an especially innovative highlight of ECO PRO Mode. Based on navigation data, it detects bends, built-up areas, roundabouts, T-junctions, speed limits and motorway exits along the route and is able to give you tips in advance to enable you to reduce speed early on. The proactive driving assistant also efficiently controls the coasting function.

  • ECO PRO Route.

    ECO PRO Mode also includes ECO PRO Route which combines with the new generation of Navigation System Professional to draw on various parameters such as individual driving style as well as the current traffic situation and road conditions to calculate the most fuel-efficient route.

  • Active Cruise Control in the ECO PRO Mode.

    Active Cruise Control in the ECO PRO Mode regulates the speed and brakes when needed until the vehicle comes to a standstill. When the traffic situation has normalised vehicle is efficiently brought back to the desired speed.

Brake Energy Regeneration.

Brake Energy Regeneration.

Sports driving dynamics.

Until now, braking meant giving away energy. Brake Energy Regeneration now puts an end to this: when you brake, energy is recovered and the battery is loaded. As soon as you release the accelerator or apply the brake, the energy liberated is used to charge the battery. This decreases the load on the engine, reduces emissions and saves fuel. The targeted generation of electrical energy has yet another advantage: At full acceleration, the engine also has the propulsive force at its disposal that would otherwise be channelled off to charge the battery in conventional systems. The result is an increase in not only cost-efficiency but also driving fun. 

8-speed Steptronic transmission.

8-speed Steptronic transmission.

Reduced background noise.

The most dynamic and comfortable way to save: the 8-speed Steptronic transmission not only ensures incredibly soft changes and reduces background noise at high speeds, it also significantly reduces fuel consumption. The transmission can be combined with all engines. Gear changes with the new 8-speed Steptronic transmission are swift and comfortable. The individual gears are finely graduated so that the change takes place with small rev intervals and the transmission process itself goes unnoticed. At the same time, the engine is always held at the performance level at which it can exploit its strength and efficiency to the optimum. It is assisted here by the newly developed and more efficient converter clutch. At high speeds, the additional gears reduce the number of revolutions, thus lowering fuel consumption and engine noise.

Most dynamic.

Thanks to the 8-speed Steptronic transmission from BMW EfficientDynamics, it is now possible to actively boost performance in vehicles with the new Predictive Drive Train via the Driving Experience Control. In the "Sport" mode, the transmission management uses data from the navigation system to deliver a level of responsiveness that is even more dynamic and spontaneous based on route characteristics. As suggested by its name, the "Comfort" mode offers a comfort-oriented shift programme with fewer shifts. BMW supplies the optional 8-speed Steptronic sport transmission for an even more agile sensation of gear-changing and driving. In addition to faster gear changes, it contains two gearshift paddles on the steering wheel and a shortened gear change lever for more dynamism. Launch Control provides extra dynamics: this motor sport-inspired function controls the start-up revs and enables maximum acceleration from standstill.
