320d. The new-generation BMW 3 Series Sedan features the BMW TwinPower Turbo four-cylinder diesel engine of its predecessor, which has been refined for even greater fuel economy and lower emissions with no reduction in power output. The thermodynamically improved turbocharger enables lively power delivery right across the load range. An electric actuator adjusts the turbine blades with split-second speed in line with different engine loads, so that when the driver demands full throttle, the engine is as responsive in the low rpm range as it is at full load. Solenoid injectors supply the fuel to the cylinders at a pressure of up to 2,000 bar. High-precision fuel metering and high atomization quality result in clean and homogeneous combustion. The 320d delivers unchanged maximum power of 135 kW/184 hp at 4,000 rpm, and torque of 380 N·m (280 lb-ft) on stream between 1,750 and 2,750 rpm. The new BMW 320d’s average fuel consumption in the EU test cycle of 4.5 liters per 100 kilometers (52.3 mpg US) and CO2 emissions of 118 grams per kilometer mark a 4% improvement on the predecessor model. BMW 320d EfficientDynamics Edition. The 2.0-liter four-cylinder engine is from the same family as the regular BMW 320d engine and shares the same all-aluminium crankcase, VNT turbocharger and latest-generation common rail direct injection. Additional features like a slight reduction in maximum output rating, the rpm-reducing, friction-reduced powertrain design and an optimized aerodynamics package give this EfficientDynamics version of the new BMW 3 Series the lowest CO2 emissions in its class. The new BMW 320d EfficientDynamics Edition develops maximum power of 120 kW/163hp at 4,000 rpm and delivers its maximum torque of 380 N·m between 1,750 and 2,750 rpm. This sedan model accelerates from 0 to 100 km/h (62 mph) in 8.0 seconds and hits a top speed of 230 km/h (143 mph). Fuel consumption is 4.1 liters per 100 kilometers (57.4 mpg US), with corresponding CO2 emissions of 109 grams per kilometer. The new BMW 320d EfficientDynamics Edition can now for the first time be combined with an eight-speed automatic transmission, and can operate just as efficiently with the new unit as with the standard six-speed manual transmission. In all road speed ranges that are relevant in everyday driving, the engineers have achieved reductions in engine speed which have noticeable benefits for fuel consumption. For example, when cruising at 100 km/h (62 mph) in sixth gear, the engine is only turning over at 1,600 rpm. The “centrifugal pendulum absorber” fitted in the engine’s dual-mass flywheel ensures smooth, vibration-free running even at low engine speeds. It efficiently counteracts irregular running and eliminates vibration when accelerating. The diesel engine revs smoothly from low engine speeds and the accompanying sound is equally refined. This extra refinement, and improvements to the Optimum Shift Indicator, encourage the driver to change to a higher gear more often and to shift down less frequently. The Edition-specific modifications include a longer final-drive ratio, an optimized aerodynamics package with a 10 mm (0.4 in.) drop in ride height and wheels with “turbine” styling. There is even a 15% reduction in the rolling resistance of the tires compared with the predecessor model. The economical diesel model also features all the fuel economy-enhancing measures used on other models in the new BMW 3 Series, including Brake Energy Regeneration, the Auto Start-Stop function and on-demand control of ancillary units such as the oil and coolant pump. Auto Start-Stop, Brake Energy Regeneration, ECO PRO mode. The new BMW 3 Series Sedan is equipped as standard with an Auto Start-Stop function, which automatically switches off the engine during short stops at traffic lights or in stationary traffic, so as not to waste fuel. For the first time, and uniquely in this class, this system can be combined with the new eight-speed automatic transmission. The new BMW 3 Series also comes with standard-fitted Brake Energy Regeneration. As far as possible, therefore, power for the vehicle electrical system is generated only during braking and overrun. When the engine is under load, the alternator can often be disengaged. This not only means that electricity can be generated with little or no effect on fuel consumption, it also grants the sports sedan livelier acceleration. Finally, the new Driving Experience Control switch gives drivers the option of selecting ECO PRO mode which, by modifying the powertrain management and programming the heating and air conditioning, the heated seats and the exterior mirrors to operate at optimum efficiency, reduces fuel consumption by as much as 20%.
