High Precision Injection

In this latest 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 to ensure particularly

BMW TwinPower Turbo Technology

recaptures the energy present in exhaust through

the use of two chargers (550i), or alternatively the

charger (535i).

8-speed automatic transmission Steptronic

The particularly smooth gear shifts of the new

8-speed automatic transmission produce greater

reduction in fuel consumption of approximately 6 %

and more comfortable gear changes.

The pleasure you get from driving a BMW is the result of meticulous engineering – always setting the benchmark because it goes far beyond outright engine performance. This is the tradition behind

emissions. Standard in every BMW.

Air vent control*

Engine management determines the engine’s

cooling requirements constantly while driving,

making a permanent airstream through the radiator

unnecessary. The air vents in front of the radiator

open or close depending on the outside

temperature and road speed. When shut, they

improve aerodynamics, shorten the engine’s

warm-up time and so reduce fuel consumption.

* May not be available in all countries. Please consult your

BMW partner.

Tyres with reduced rolling-resistance*

While driving, tyres are constantly changing shape. This uses

energy and thus fuel. Tyres with reduced rolling-resistance

have an improved design and use special materials for their

treads and sidewalls, which limits deformation.

Brake Energy Regeneration*

To supply the battery with electrical energy, the generator is

ordinarily driven using engine power, which demands permanent

fuel consumption. Brake Energy Regeneration means the

generato

r produces electricity when the driver either takes his

foot off the accelerator or brakes – while coasting, previously

unused kinetic energy is transformed into electrical energy

before being fed into the battery. This fuel-free charging process

is indicated by a symbol on the rev counter (page 55).

and are not available for all model variants. Your BMW partner or subsidiary will

be happy to inform you of all equipment details.

Lightweight engineering

Where it makes sense to use light materials, our

engineers use aluminium – for example, in the

front part of the car and the chassis. Additionally,

the roof is entirely aluminium and, thanks to an

aluminium crankcase, the six-cylinder diesel

engine is among the lightest in its class. The

weight savings reduce fuel consumption and

at the same time optimise the axle load

distribution for improved dynamics.

This has gone in.

in the quest to bring you more driving pleasure and

lower fuel consumption.

Less fuel. More performance.

And this is what comes out.
