THE ECONOMY OF MOVEMENT.
BMW EfficientDynamics in the BMW 2 Series Active Tourer.
Like all top athletes, the BMW 2 Series Active Tourer knows how to use its strength to the maximum effect. Thanks to BMW TwinPower Turbo technology and intelligent BMW EfficientDynamics energy management, which help to ensure lower fuel consumption and emissions. But there’s one thing that isn’t reduced in the slightest: BMW typical driving pleasure.
BMW TWINPOWER TURBO TECHNOLOGY.
Thanks to BMW TwinPower Turbo technology, the innovative BMW petrol and diesel engines facilitate markedly more agile power delivery and outstanding responsiveness even at low rpms, all while being exceptionally fuel efficient and low in emissions. The newest generation of engines from the EfficientDynamics family combine cutting-edge fuel-injection technologies and completely variable power distribution with innovative turbocharger technology to enhance efficiency and dynamics.
Power and efficiency in one
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. The coasting function (only with Steptronic transmission) and ECO PRO Route (only with Navigation System) offer an increased savings potential.
ECO PRO Route
The ECO PRO Route shows the most efficient route based on the traffic situation, driving style and road conditions. The on-board computer shows the percentage of fuel that can be saved by taking the ECO PRO Route.
The coasting function decouples the drive train from the engine and the vehicle rolls without the transmission. The car "coasts" when the driver takes the foot from the gas between 50 and 160 km/h and does not apply the brakes. In combination with Active Cruise Control, the vehicle also accelerates back to the desired speed more efficiently after braking when in ECO PRO Mode.
AUTOMATIC START/STOP FUNCTION.
The Automatic Start/Stop function ensures that fuel is only used when the car is moving. When the vehicle comes to a temporary stop, for example at traffic lights or in stop-and-go traffic, the Automatic Start/Stop function saves fuel by switching off the engine as soon as the car is idling and the foot is off the clutch (manual transmission), or when the car comes to a complete standstill (Steptronic transmission).
A signal in the Info Display indicates when the Automatic Start/Stop function is active. As soon as the clutch is pressed (manual transmission) or the foot taken from the brake (Steptronic transmission), the engine springs back to life automatically.
BRAKE ENERGY REGENERATION.
Every time the brakes are hit, kinetic energy is generated and until recently this energy went unused. Brake Energy Regeneration takes advantage of this long-overlooked potential. It harnesses the coasting energy that is generated whenever the driver brakes or takes his or her foot off the accelerator and turns it into electricity. This electricity is then used to charge the car battery. The intelligent energy management system means that the alternator no longer needs to run constantly, which reduces the strain on the generator. The result: reduced fuel consumption and increased performance – classic BMW EfficientDynamics.
OPTIMUM SHIFT INDICATOR.
Optimum, perfectly-timed gear changes can help save fuel, particularly in urban traffic and over long distances. Change gears at the right time, use less fuel – the engine’s electronics system identifies the most efficient gear, based on road conditions and engine speed. An arrow lights up in the Info Display to show when it would be more efficient to shift into a higher or lower gear. The system also recognises quick acceleration, and will delay its recommendation accordingly until the engine speed is up. Comparative tests have shown that vehicles with the Optimum Shift Indicator use around four percent less fuel.
