What appears to be a conventional diesel 3 Series hides some engineering advances which make this model the 320d EfficientDynamics Saloon, to give it its full name a massive step forward over its stablemates.

Dropping below 110g/km means this model attracts the full first year writing down allowances, allowing outright purchase fleets and leasing companies the opportunity to offset the car's full first year depreciation against tax.
At 109g/km and claimed fuel economy of 68.9mpg, this new version has slightly less power (163bhp vs 177 in the regular 320d), a smidgeon more torque yet vastly improved efficiency the normal 320d emits 128g/km and returns 58.9mpg.
Naturally, the new model comes with the full suite of EfficientDynamics technology (low rolling resistance tyres, stop-start, gearshift indicator, lower ride height), but BMW has re-engineered the flywheel so that it vibrates less, eliminating that stuttering when diesels are out of the torque band.
As a result, the new 320d is much smoother at lower revs, meaning drivers are more inclined to stay in a higher gear, improving fuel economy.
And it really works, the engine pulling smoothly from low speed in high gears. While BMW engineers say that they have had to compromise the driving dynamics of the 320d slightly to get down to 109g/km, in real-world driving it feels little different to the regular 320d model.
Four-cylinder diesel engine with optimised efficiency and superior performance all in one.
The BMW 320d EfficientDynamics Edition is powered by a four-cylinder diesel engine specifically optimised for even greater fuel economy and emission management and, therefore, for a standard of efficiency never seen before. All this comes from the 2.0-litre four-cylinder power unit with its all-aluminium crankcase, turbocharging and the latest generation of common-rail fuel injection featured with various power stages also in the BMW 316d, the BMW 318d and the BMW 320d. The engine specially conceived for the BMW 320d EfficientDynamics Edition develops maximum output of 120 kW/163 hp at an engine speed of 3,500-4,200 rpm and peak torque of 360 Newton-metres/265 lb-ft all the way from 1,750 to 3,000 rpm.
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. The shift in load points beneficial to fuel economy and emissions goes together in this case with full maintenance of the spontaneity and running smoothness so typical of a BMW diesel.
Centrifugal pendulum in the two-mass flywheel for smooth and comfortable motoring without vibrations even at very low engine speeds.
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.
The driving dynamics characteristic of a BMW are borne out also by the car's acceleration to 100 km/h in just 8.2 seconds and by the BMW 320d EfficientDynamics Edition accelerating in fifth gear from 80-120 km/h in 9.6 seconds. Top speed is 225 km/h or 140 mph.
