The New BMW 320d EfficientDynamics Edition: Yet Another Step Ahead

Munich. Premium car maker BMW is further increasing its substantial lead in the development of particularly clean and at the same time very dynamic cars
of the highest standard. Teaming up with the BMW 320d, the new BMW 320d ¬EfficientDynamics Edition is being presented for the first time at the 2009 Frankfurt Motor Show. This unique saloon combines fuel consumption of just 4.1 litres diesel/100 kilometres (equal to 68.9 mpg imp) and a CO2 rating of 109 grams per kilometre in the EU test cycle with engine output of 120 kW/163 hp.
The 2.0-litre four-cylinder diesel engine of this high-tech model boasts an
all-aluminium crankcase, turbocharging with variable intake geometry and common-rail direct fuel injection complete with piezo-injectors. With the engine and the entire car modified once again for an even higher standard of efficiency, this unique saloon targeted above all at the German, Italian, French and Spanish markets comes with optimised aerodynamics, an extra-long final drive ratio, and an innovative two-mass flywheel incorporating a centrifugal-force pendulum.
All this makes the BMW 320d ¬EfficientDynamics Edition the most fuel-efficient and lowest-emission car in BMW’s current model range. In the fiercely contested midrange segment it is an unparalleled, highly attractive premium offer for the truly demanding and progressive customer focusing primarily on superior economy and the environment, without wishing to forego the sporting driving characteristics so typical of a genuine BMW.
The enhanced efficiency already offered by the existing models in the BMW 3 Series thanks to BMW ¬EfficientDynamics making these cars superior to their competitors, is now raised to an even higher level in the BMW 320d EfficientDynamics Edition.

The rims have something weird...the brakes are not visible anymore. Everything is covered for less drag!

BMW kan keep the wheels - I prefer my wheels. Thank you.

^ You do notice it's not just some different design right? They're quite small, but the design is not bad, and this will be very aerodynamic with no wind being able to go behind it anymore.

There isn't this plate on the car, is it?!

edit: see here - probably the plate is just for the press pics to show it better.

Centrifugal pendulum in the two-mass flywheel for smooth and comfortable motoring without vibrations even at very low engine speeds.

The engine stands out in particular through its sporting and dynamic power from low revs. The innovative centrifugal-force pendulum incorporated in the two-mass flywheel, together with the longer transmission ratio, serves to significantly reduce the level of engine speed at all road speeds relevant in practice in the BMW 320d -EfficientDynamics Edition.

To ensure smooth driving characteristics free of vibration also when driving at particularly low engine speeds, the power unit of the BMW 320d EfficientDynamics Edition features a so-called centrifugal pendulum efficiently compensating any unsmoothness in running characteristics typically encountered at low revs. This innovative component is integrated in the engine’s two-mass flywheel where it dampens the vibrations generated under load, thus ensuring comfortable and acoustically optimised development of power and performance all the way from low engine speeds.
This increase in motoring comfort will encourage the driver to use a higher gear more often or, respectively, not to shift back as he otherwise would do. But when accelerating the BMW 320d -EfficientDynamics Edition still offers the driving behaviour and agility so typical of BMW.

No no, the rims are normal by appearances... in other words there is no backing plate or sealing off of the rim from the brake discs.
