This has gone in.
The pleasure you get from driving a BMW is the result of fine engineering – always setting the benchmark because it is based on much more than engine power. This is the tradition
behind BMW EfficientDynamics. 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 EfficientDynamics technology package as standard that boosts dynamics even further whilst simultaneously reducing fuel consumption and CO2emissions.
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 flexible 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 efficiency.
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.
Valvetronic
Valve lift control is fullyvariable in engines with Valvetronic. The result is
improved cold start behaviour and smoother running, as well as a significant
drop in fuel consumption.
Optimum Shift Indicator
Timely gear shifts are one of the most effective and easiest ways to
save fuel. This is where Optimum Shift Indicator in conjunction with
6-speed manual transmission comes in. It shows the driver what gear
to use in order to save fuel.
Some BMW EfficientDynamics featuresare 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.
