High Precision Injection

In this cutting-edge generation of direct injection,

the Piezo injectors in the BMW  Series Gran

Turismo are positioned very close to the spark

plugs. They inject fuel at high pressure and with

extreme precision. Several injections are possible

per ignition process. Thanks to fast and ﬂ exible

electronic control, the timing and quantity of

injections can be precisely adjusted to the power

requirement, the temperature, and the pressure in

the cylinder – for more output and greater

efﬁ ciency.

BMW TwinPower Turbo Technology

This innovative exhaust turbocharger efﬁ ciently

recaptures the energy present in exhaust through

the use of two turbochargers.

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 just engine power. This is the tradition behind BMW

Efﬁ cientDynamics. It includes the visionary hydrogen-powered engine already used in the Hydrogen  – a nearly emission-free BMW  Series Sedan. Also in production is the new BMW ActiveHybrid

– an intelligent, performance-oriented engine combining combustion and electronics. And every BMW already includes many technologies that boost dynamics while simultaneously reducing fuel

consumption and emissions.

-speed automatic transmission with

Steptronic

The particularly smooth gear shifts of the new

-speed automatic transmission produce greater

engine efﬁ ciency at every speed. The result: a

reduction in fuel consumption of approximately

% and more comfortable gear changes.

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

generator produces electricity when the driver takes his or her

foot off the accelerator – while coasting or braking, previously

used 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 ).

Lightweight engineering

Our engineers use lightweight aluminum

throughout our vehicles, in the front section,

for example, or for the suspension. Additionally,

the doors, roof and rear tailgate structure are

entirely aluminum in the BMW  Series Gran

Turismo. The weight savings reduce fuel

consumption and at the same time optimize

axle load distribution for improved dynamics.

This is what we’ve engineered into our vehicles.

Thanks to innovative Efﬁ cientDynamics features, BMW

has been able to signiﬁ cantly reduce CO



emissions

and fuel consumption in many models. But that’s just

the beginning. We’re carrying on our research in terms

of Efﬁ cientDynamics – in the quest to bring you even

more driving pleasure with even fewer emissions.

BMW Efﬁ cientDynamics

Less emissions. More driving pleasure.

And this is what comes out.
