As a part of our sustainability strategy, BMW was one of the fi rst manufacturers to pursue the goal of
effi cient driving technologies. BMW Effi cientDynamics represents the most comprehensive package of
innovative technologies for reducing fuel consumption and emissions – while simultaneously increasing
driving dynamics – currently in standard production. To date, BMW has rolled out more than two million
vehicles worldwide equipped with Effi cientDynamics technologies. As a result, BMW has been able to
reduce the CO
emissions of its fl eet by approximately percent since .
Vision becomes reality: BMW Vision Effi cientDynamics.
In , BMW plans to introduce a + sports car that will feature groundbreaking plug-in hybrid
technology with compact-class consumption, yet still retain sports-car performance. The BMW Vision
Effi cientDynamics test model has a latest-generation full-hybrid system with an output of hp.
A three-cylinder turbo diesel engine, as well as a hybrid synchronous engine on the front axle, and
full-hybrid drive system on the rear axle, give the vehicle an impressive range. This innovative vehicle’s
performance-to-fuel-consumption ratio is, quite simply, without equal.

BMW EFFICIENT DYNAMICS: WE PUT EVERYTHING INTO
GETTING THE MOST OUT OF OUR VEHICLES.
At BMW, we create dynamic vehicles that thrill you with quick acceleration, predictable handling and reassuring control. We are also busy
fi nding innovative fuels and technologies that help preserve the environment while delivering legendary performance. This is what we refer
to as Effi cientDynamics. This goal led to the visionary CleanEnergy hydrogen-powered engine in the BMW Hydrogen Sedan. In ,
BMW introduced Advanced Diesel with BluePerformance in the U.S., offering diesel with reliable power, increased fuel effi ciency and reduced
emissions. A year later, BMW’s ActiveHybrid X and ActiveHybrid vehicles combined combustion and electric power to boost performance
while simultaneously reducing fuel consumption and CO
emissions. And now, a completely new vehicle concept is targeted to meet the need
for sustainable mobility in fast-growing metropolitan areas, in the shape of the BMW i .
Air Curtain. Narrow openings on the left and right of the front air dam
of the i direct in owing air into two sealed channels. These run along
the inside of the front to the wheel arches, where the air re-emerges and
is steered at high speed through a narrow opening close to the external
surface of the wheel. The escaping air streams down the sides of the
front wheels, minimizing air turbulence around the wheels and wheel
arches, thereby further reducing fuel consumption.
Double-VANOS. VANOS is BMW’s valve timing system that can
“steplessly” vary the points in the combustion cycle when valves open
and close. Double-VANOS refers to the fact that it operates on both the
intake and exhaust camshafts. Electronically controlled in response to
engine speed, load and temperature, VANOS reduces emissions, and
enhances low- to medium-speed torque, as well as fuel effi ciency.
Valvetronic. BMW’s Valvetronic valve control system improves engine
response and refi nement, while also helping to reduce fuel consumption.
Instead of using a traditional throttle, the system helps the engine
“breathe” better by providing fully variable lift adjustment of the inlet
valves. The result: improved cold starts, smoother running, and a
signifi cant drop in fuel consumption.
Ef cient transmissions. The Series Convertible offers a choice of
transmissions, each designed to maximize effi ciency. In both models,
a smooth-shifting -speed manual transmission is standard. In the i,
a -speed
STEPTRONIC automatic transmission is also offered; the
-speed Double Clutch Transmission (DCT) is available for the i.
Lightweight construction. Our engineers use lightweight aluminum
throughout our vehicles – in the front section, for example, or for the
suspension. BMW’s six-cylinder TwinPower Turbo engine is all aluminum;
the naturally aspirated inline six is an aluminum/magnesium composite –
the lightest in its class. Taken together, these weight savings lead to
lower fuel consumption and better axle load distribution for more agility,
especially in curves.
BMW TwinPower Turbo Technology. The -hp i benefi ts
from BMW’s TwinPower Turbo engine with Valvetronic technology that
delivers quick acceleration with virtually no “turbo lag.” Fuel economy
is impressive, as well, thanks to High Precision Direct Injection that
ensures lean-burn operation under partial loads by providing optimum
combustion of fuel.
