Auto Start-Stop function.
Even when idling, such as at a stop sign, an engine burns fuel. The
BMW Auto Start-Stop function enhances fuel effi ciency by switching off
the engine. (The intelligent electronics system fi rst checks the battery
charge level and calculates if other electric systems, like the rear-window
defroster, need more energy.) Once the brake pedal is released, the
engine starts up again almost instantly. A Start-Stop signal in the display
indicates the function is active.
Brake Energy Regeneration.
In Brake Energy Regeneration, the alternator generates electricity only
when the driver takes his or her foot off the accelerator. Kinetic energy
that was previously unharnessed is transformed into electrical energy,
then fed into the battery. In this way, electricity is generated without
consuming fuel.
Aerodynamics.
Carefully optimized aerodynamics ensure a low drag coeffi cient – and,
therefore, a positive effect on overall effi ciency. A host of aerodynamic
features in the  Series include fl at underbody paneling, the optimized
design of the front air dam and air intakes, and airfl ow management
measures in the wheel arches.
Electric Power Steering.
Unlike conventional, hydraulic steering systems, electric power steering
draws power only during actual steering movements. When the steering
wheel position is con stant, the electric motor is inactive.
BMW TwinPower Turbo technology.
This innovative turbocharging technology effi ciently reclaims the energy
contained in exhaust gases by using a twin-scroll charger.
-speed
STEPTRONIC automatic transmission.
The close spacing of gear ratios in this -speed automatic transmission
makes maximum use of the optimum rev range, reducing fuel consump-
tion and allowing smoother shifts.
ECO PRO mode.
Fuel-consumption-friendly ECO PRO mode adapts accelerator pedal and
gearbox responses while also moderating the heating/air conditioning
systems to maximize effi ciency. The new ECO PRO Route function takes
traffi c density, individual driving style and local conditions into account,
then offers directions optimized for effi ciency while adding minimal travel
time. The displayed fuel consumption benefi t lets you decide whether or
not to follow this recommendation.
Not all BMW Effi cientDynamics features are available on all models.

BMW EFFICIENT DYNAMICS:
MAKING A LITTLE GO A LONG WAY.
BMW was one of the fi rst automotive manufacturers to pursue effi cient driving technologies – one part of our award-winning sustainability strategy.
BMW Effi cientDynamics repre sents the most comprehensive package of innovative technologies currently in production for reducing fuel consumption
and emissions. Our commitment to Effi cientDynamics means we are continuously developing innovative systems that bring us closer to our long-term
goal of emissions-free mobility. Since  BMW has been able to reduce the CO

emissions of its entire fl eet by approximately  percent, and
intends to achieve a further  percent reduction by . However, we remain committed to driving pleasure, which is being pursued in different ways.
Eco-friendly technology. The development of more effi cient vehicles powered by conventional gasoline and diesel engines are continuing
challenges. A comprehensive technology directive enables the reduction of fuel consumption and emissions, while at the same time increasing power
output and driving enjoyment. These advances are based on innovations such as BMW TwinPower Turbo technology, Brake Energy Regeneration,
Air Curtain front apron design, and many others.
BMW ActiveHybrid. With the BMW ActiveHybrid , BMW ActiveHybrid  and BMW ActiveHybrid , BMW has impressive hybrid production models
in its line. All combine outstanding effi ciency with superlative dynamic ability.
BMW i. The all-new BMW i brand is launching two completely new vehicle concepts for sustainable mobility in an urban environment; both are an
important part of BMW Effi cientDynamics technologies. Key features of the BMW i and BMW i include the use of lightweight materials such as
carbon-fi ber-reinforced plastic (CFRP), electric drive systems, powerful battery technology and eco-friendly production methods.
