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 Hydrogen engine, already used in a number of completely emission-free BMW Hydrogen 7 vehicles, and 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 CO
2
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. The
injectors’ central positioning means only part of
the combustion chamber needs to be filled with
an ignitable petrol-air mixture. This enables
efficient, “lean” engine operation, especially in
the heavily used part-throttle range.
Air vent control
Engine management signals the engine’s
cooling requirements 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 fully variable in engines with Valvetronic. The result is
improved engine response 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 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.
Thanks to the innovative features of
EfficientDynamics, BMW has been able
to significantly reduce CO
2
emissions
in many models. But that’s just for starters.
We’re carrying on our research with
BMW EfficientDynamics – in the quest
to bring you more driving pleasure and
less emissions.
And this is what comes out.

Less emissions. More driving pleasure.
