This has gone in.
The pleasure you get from driving a BMW is the result of ne engineering – always setting the benchmark because it is based on much more than engine power. This is the tradition behind
BMW Ef 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 Ef cientDynamics technology package as standard that boosts dynamics even further while signi cantly reducing fuel consumption and CO
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 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 ef ciency.

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
Ef cientDynamics, BMW has been able
to signi cantly reduce CO

many models. But that's just for starters.
We're carrying on our research with
Ef cientDynamics – in the quest to bring
you more driving pleasure and less
emissions.
