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
fi lled with an ignitable petrol-air mixture. This enables effi cient, “lean”
engine operation, especially in the heavily used part-throttle range.
BMW TwinPower Turbo Technology
This innovative turbocharging process very effi ciently recycles exhaust
gas energy by dividing the gas fl ow and directing it through a TwinScroll
turbocharger (335i). In conjunction with the fully variable Valvetronic
valve control system and High Precision Injection, fuel consumption is
reduced drastically – while at the same time, output power increases
across a considerable rev range.
Electric Power Steering
Unlike conventional, hydraulic steering systems,
the electrical steering only uses energy during
actual steering. When the steering wheel
position is constant – for example at high speed
along the motorway – the electric motor is
inactive.
Tyres with reduced rolling-resistance*
While driving, tyres are constantly changing
shape. This uses up energy and thus fuel.
Tyres with reduced rolling-resistance have an
improved design and use special materials for
their road treads and side walls, thus reducing
deformation.
THIS HAS GONE IN.
Auto Start/Stop function
BMW four-cylinder engines with 6-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 signifi cantly reduces fuel consumption,
especially in city traffi c.
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.

BMW BluePerformance*
When equipped with the 6 -speed manual
transmission, the BMW 3 2 0 d and 3 3 0 d Saloon
are optionally available with the new BMW
BluePerformance technology. This uses an
NOx storage catalytic converter to store the
nitrogen oxides produced by lean-burn
combustion. Brief, cyclical intervals in which
a rich mixture is burned then reduce nitrogen
emissions to a minimum. In this way, the
BMW 3 2 0 d and 3 3 0 d Saloons with
BluePerformance technology already meet
the future EU6 emissions standard.
The pleasure you get from driving a BMW is the result of fi ne engineering – always setting the benchmark because it is based on much more than engine
power. This is the tradition behind BMW Effi cientDynamics. It includes the visionary Hydrogen engine, already used in completely emission-free BMW
Hydrogen 7 vehicles, and the BMW ActiveHybrid – an intelligent, demand-oriented combination of internal combustion engine and electric motor.
And every BMW already includes the multi-award-winning BMW Effi cientDynamics technology package as standard that boosts dynamics even
further whilst simultaneously reducing fuel consumption and CO2emissions.
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 6-speed manual transmission comes in. It shows the driver what
gear to use in order to drive more effi ciently.
