THE BMW SERIES SALOON.
THE DRIVING FORCE.
Sporty, stylish, elegant – as a driver, one might almost become jealous.
Many follow the new trend.
BMW EfficientDynamics was the one to establish it.
Every sport needs a hero.
What you see will thrill you.
What you don’t see will reassure you.
You drive and
iDrive handles the rest.
Escape from the everyday – every day.
This has gone in.
The pleasure you get from driving a BMW is the result of ne engineering – always setting the benchmark because it is based on much more than engine power. This is the tradition behind BMW Ef cientDynamics. It includes the visionary Hydrogen engine, already used in a number of completely emissionfree 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 the multi-award-winning BMW Ef cientDynamics technology package as standard that boosts dynamics even further whilst simultaneously reducing fuel consumption and CO2 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 belled with an ignitable petrol-air mixture. This enables ef cient, “lean” engine operation, especially in the heavily used part-throttle range.
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 signi cantly reduces fuel consumption, especially in city traf c.
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 ef ciently.
BMW BluePerformance*
When equipped with the -speed manual transmission, the BMW d Saloon
is 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 d Saloon with BluePerformance technology already meets the future EU emissions standard.
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.
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.

And this is what comes out.
BMW already offers 24 models with CO2 emissions of 140 g/km and signi cantly less. But that’s just for starters. We’re carrying on our research with Ef cientDynamics – in the quest to bring you more driving pleasure
and less emissions.
