Tyres with reduced rolling-resistance

While driving, tyres are constantly changing shape. This uses up energy and

thus fuel. Tyres with reduced rolling-resistance have an improved design

and use special materials for their road treads and side walls, thus reducing

deformation.

This has gone in.

The pleasure you get from driving a BMW is the result of ﬁ ne engineering – always setting the benchmark because it is based on much more than engine power. This is the tradition behind

BMW Efﬁ cientDynamics. It includes the visionary CleanEnergy hydrogen-powered engine, already used in a number of completely emission-free BMW 7 Series Saloons. Also going into

production soon is the BMW ActiveHybrid – an intelligent, demand-oriented combination of internal combustion engine and electric motor. And every BMW already includes a multi-award-winning

BMW Efﬁ cientDynamics technology package as standard that boosts dynamics even further while signiﬁ cantly reducing fuel consumption and CO

emissions.

High Precision Injection

In this cutting-edge generation of petrol direct injection, the Piezo injectors are positioned very close to the spark plugs. They inject

the fuel at high pressure and with extreme precision. Several injections are possible per ignition process. Thanks to fast and ﬂ exible

electronic control, the timing and quantity of the injections can be precisely adjusted to the power requirement, the temperature and

the pressure in the cylinder – for more output and greater efﬁ ciency.

Air vent control

Engine management signals the engine’s current

cooling capacity requirements constantly while

driving, rendering a permanent airstream through

the radiator unnecessary. The air vents in front

of the radiator open or close depending on the

environmental temperature and road speed.

When shut they improve aerodynamics, shorten

the engine’s warm-up time and so reduce fuel

consumption.

Brake Energy Regeneration

To supply a battery with electrical energy, the generator (alternator) is

permanently driven using engine power, which demands additional

fuel consumption. Brake Energy Regeneration means the generator

usually only generates electricity when the driver either takes the

foot off the accelerator or brakes – previously unused kinetic energy

is transformed in coasting mode into electrical energy before being

fed into the battery. In this way, electricity is generated while coasting,

without consuming fuel.

Some BMW EfficientDynamics features are dependent on the car’s equipment and are

not available for all model variants. Your BMW partner will be happy to provide you with

information on all equipment details.

And this is what comes out.

Thanks to innovative features of

Efﬁ cientDynamics, BMW has been able

to signiﬁ cantly reduce CO

emissions in

many models. But that’s just for starters.

We’re carrying on our research with

Efﬁ cientDynamics – in the quest to bring

you more driving pleasure and less

emissions.

BMW Efﬁ cientDynamics

Less emissions. More driving pleasure.
