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 completely emission-
free BMW Hydrogen 7 vehicles and BMW ActiveHybrid technology, an intelligent, demand-oriented combination of internal combustion engine
and electric motor. Every BMW, in fact, already includes a multi-award-winning BMW EfficientDynamics technology package as standard, boosting
dynamics even further while simultaneously reducing fuel consumption and CO

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
the 6-speed manual transmission, comes in.
It shows the driver what gear to use in order
to drive more efficiently.
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 the 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.

and less emissions.
