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 Hydrogen engine, already used in a number of completely
emission-free BMW 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 while simultaneously reducing fuel consumption and COemissions.
THIS HAS GONE IN.
Optimum Shift Indicator
Timely gear shifts are one of the most effective
and easiest ways to save fuel. This is where
the Optimum Shift Indicator in conjunction
with -speed manual transmission comes in.
It shows the driver what gear to use in order to
save fuel.
Valvetronic
Petrol engines with Valvetronic have fully
variable valve lift control. This improves
the engine’s responsiveness and running
smoothness while also significantly reducing
fuel consumption.
Auto Start/Stop function
BMW four-cylinder engines with -speed
manual transmission automatically shut down
when the vehicle is stationary, for example at
a red light or in a jam, when the driver activates
the clutch and switches to neutral. The engine
restarts as soon as the clutch is activated
again. This innovation significantly reduces
fuel consumption especially in city traffic.
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 takes his foot off the
accelerator or the brake – 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.
Disengageable
air conditioning compressor
If the air conditioning is not being used, the air
conditioning compressor in all diesel models is
uncoupled from the belt drive, which prevents
the usual loss of energy.
Common Rail Injection system
The third-generation electronically controlled
Common Rail Injection system generates
pressure of up to , bar. Diesel fuel can be
injected with greater precision and in exactly
calculated amounts. This lowers consumption
and emissions while at the same time enhancing
engine performance.
