Handles extremely well, over the top fast and is capable of more highway fuel economy than anything seen in the US since the original Insight.

Meet the 2010 BMW 320d EfficientDynamics, where’s ours?
With the introduction of the new BMW 320d EfficientDynamics Sedan, BMW is about to offer the most fuel efficient and greenest 3 Series ever created. The latest model sets a new benchmark in the premium segment recording CO2 emissions of just 109g/km and a combined consumption figure of 57.4 mpgUS combined on the NEDC (~ 47 mpgUS combined on the 08 EPA).
The new BMW 320d EfficientDynamics Sedan offers the strongest demonstration yet of the success of the company’s pioneering EfficientDynamics program. This new model is, for the moment, the best example of what is possible; not by using hybrid technology or electric power but by refining still further the enduring internal combustion engine.
Continuing with the philosophy, BMW will not charge extra for all the measures that make the impressive performance figures possible. The BMW 320d EfficientDynamics Sedan will share exactly the same retail price as the 320d SE Sedan. The cleanest 3 Series shares an identical specification (excluding 16-inch aero alloy wheels) that includes automatic A/C, rear Park Distance Control and an auto dimming rear mirror, to name a few.
2010 BMW 320d Highlights
- Most efficient BMW 3 Series ever
- New 2.0L Turbo-diesel engine.
- 163 HP/280 lb-ft of torque
- 0 to 60 in < 8.0 seconds
- Top speed - 142 mph
- 57.4 mpgUS combined on the NEDC
The new BMW 320d EfficientDynamics Sedan is powered by a smooth 1,995cc engine with class-leading performance figures. The single turbocharged diesel powerplant features an all-aluminum crankcase and third generation common-rail injection technology with high pressure piezo injectors to achieve its impressive consumption and emissions figures without diluting driver enjoyment.
The remarkable range of abilities displayed by the BMW 320d EfficientDynamics Sedan is due not only to the full range of EfficientDynamics elements, but also to some new technologies that take the concept to a new level. It uses the same new all-aluminum 2.0L diesel engine as the standard BMW 320d, with new developments to minimize friction and improve thermodynamics – resulting in more efficient motoring that is easy and comfortable to achieve.
Diesel engines are most efficient at lower engine speeds, but they suffer greater vibration at low revs. The challenge for BMW’s engineers was to minimize engine noise and restore comfort to allow drivers the use of lower revs.
BMW achieved this by deploying centrifugal pendulum absorbers within the two mass flywheel to compensate for the rotational lack of balance at lower speeds, smoothing out any engine vibration through the drivetrain. With this problem solved they could now choose a taller final drive ratio and a gearshift indicator that encourages earlier up-shifts. These technologies allow drivers to spend a greater proportion of time in a higher gear and at a lower engine speed, thereby lowering fuel consumption.
The BMW 320d EfficientDynamics Sedan incorporates the full spectrum of BMW EfficientDynamics technologies already featured across the 3 Series range. From the lowered suspension and specially designed aerodynamic alloy wheels with Michelin EnergySaver tires to the cars superlative drag coefficient of just 0.27, the 320d EfficientDynamics Sedan is like nothing in its class.
Chassis and Safety
BMW is renowned for producing the ‘Ultimate Driving Machine’ and the BMW 3 Series has set the benchmark since its 1975 debut. The new BMW 320d EfficientDynamics Sedan might be aimed at low emissions and a high mpg figure, but this has not diluted this decades old mission statement. The car still features a front engine, rear-wheel-drive configuration combined with 50:50 weight distribution, and the use of advanced lightweight materials on the body and the suspension add up to an award-winning combination.
The suspension of the new 320d EfficientDynamics Sedan is an example of lightweight engineering that enhances the driving characteristics of the car. The entire front axle subframe including the tie bars, track control arms and pivot bearings are made of aluminum. The independent rear suspension also features a five-arm arrangement for optimum handling.
In addition, the chassis ride height has been lowered by .6” to improve aerodynamic efficiency, while unique 16-inch ‘aero’ wheels enhance the airflow in the wheel arch area and are standard fitment. These light weight wheels are equipped with Michelin low rolling resistance tires that improve aerodynamics and reduce drag.
As with all 3 Series derivatives, drivers of the new BMW 320d EfficientDynamics Sedan can be reassured that they will be protected by one of the most advanced safety systems available on any car. The car provides unrivalled passenger cell safety with frontal, hip and thorax airbags, latch belt tensioners and belt force limiters activated by sensor-controlled safety electronics, depending on the type and severity of a collision.
The BMW 320d EfficientDynamics Sedan comes with a Dynamic Stability Control system incorporating Dynamic Traction Control and Corner Brake Control along with ABS as standard. The DSC system constantly monitors speed, steering inputs, lateral acceleration and yaw rate and, should it determine that control is being lost, DSC retards engine power or applies the brakes to re-balance the car.
The BMW 320d EfficientDynamics Sedan is a five-star crash rated car by Euro NCAP.
: What are the technical differences versus a “normal” BMW 320d?
: The BMW 320d EfficientDynamics Sedan has a maximum output of 163 HP, 21 HP less than the ‘standard’ BMW 320d Sedan. It also has optimized aerodynamics thanks to new aero alloy wheels and a .6” lower body. Far-reaching improvements in efficiency through engine modifications, a modified transmission ratio, special tires with minimum roll resistance, and a modified gearshift point indicator complete the unique offering.
