Technical data

BMW was one of the fi rst automotive manufacturers to pursue the goal of effi cient driving technologies,
as part of a multi-award-winning sustainability strategy. BMW Effi cientDynamics represents an acclaimed
standard package of innovative technologies that reduce fuel consumption and emissions, while
simultaneously enhancing dynamic performance. 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 .

Auto Start-Stop function.
Even when idling, such as at a stop sign, an engine burns fuel. BMW’s
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 heated rear window,
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.
BMW TwinPower Turbo technology.
This innovative twin-scroll turbocharging technology effi ciently reclaims
the energy contained in exhaust gases, using a twin-scroll charger with
a double-fl ow exhaust system.
Brake Energy Regeneration.
To supply a battery with electrical energy, the generator (alternator) is
usually driven using engine power, which requires fuel. With Brake
Energy Regeneration, the alternator generates electricity only when
you take your foot off the accelerator. Kinetic energy that was previously
unharnessed is transformed into electrical energy, which is then fed into
the battery. In this way, electricity is generated without consuming fuel.
Electric power steering.
Unlike conventional, hydraulic steering systems, electric power steering
draws power only during actual steering movements. When the steering
wheel position is constant, the electric motor is inactive.
ECO PRO mode.
Driving in ECO PRO mode helps customers achieve fuel savings of up
to  percent, depending on their individual style of driving. This mode
optimizes accelerator and transmission response as well as shift points,
and intelligently adapts the heating/air condition ing strategy. ECO PRO
tips help the driver drive even more effi ciently. The bonus range shown
by the on-board computer indicates how many additional miles the driver
has gained thanks to the increased effi ciency in ECO PRO mode since
the last fi ll-up.
Lightweight construction.
Our engineers use lightweight aluminum throughout our vehicles – in
the front section, for example, or for the suspension. BMW’s four- and six-
cylinder TwinPower Turbo engine blocks are all-aluminum. Taken together,
these weight savings lead to lower fuel consumption and better axle load
distribution for more agility, especially in curves.
High Precision Direct Injection.
In this latest-generation direct fuel injection system, the piezo injectors
are positioned very close to the spark plugs. They inject fuel at high
pressure, with extreme precision, for very effi cient combustion.
Not all BMW Effi cientDynamics features are available on all models.

THE BMW X’S EFFICIENT DYNAMICS
INITIATIVE AT A GLANCE.
BMW EFFICIENT DYNAMICS:
MAKING A LITTLE GO A LONG WAY.
Under the umbrella of the BMW Effi cientDynamics project, BMW is continuously developing innovative systems that will bring us closer to the goal of
emissions-free driving in the long term.
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.
