BMW is launching the most fuel efficient and greenest 3 Series ever with the introduction of the new BMW 320d EfficientDynamics, offering CO2 emissions of 109g/km and claimed average fuel economy of 4.1 liters diesel/100 kilometers (57.37mpg US). The new BMW 320d EfficientDynamics Edition will be presented for the first time at the 2009 Frankfurt Motor Show.
The new BMW 320d EfficientDynamics is powered by a mellifluous 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 piezo injectors to achieve its impressive consumption and emissions figures without diluting driver enjoyment.
The BMW 320d EfficientDynamics Saloon develops 163hp between 3,500rpm to 4,200rpm and 360Nm of torque from 1,750rpm to 3,000rpm. This equates to a zero to 62mph time of 8.2 seconds and a top speed of 137mph. Acceleration in fifth gear from 50mph to 75mph is also suitably swift taking just 9.6 seconds.
The heightened performance of the BMW 320d EfficientDynamics Saloon has been made possible due to changes to the engine construction, a longer rear axle transmission ratio, lowered suspension and the use of specially designed aerodynamic alloy wheels with Michelin EnergySaver tires.
The BMW 320d EfficientDynamics Saloon also comes with a dual mass flywheel with springs between the two parts to help smooth out any engine vibration through the drivetrain. This is enhanced with the fitting of new Centrifugal Pendulum Absorbers to improve smoothness further. This feature increases motoring comfort and should result in the driver using a higher gear more often. This innovation combined with the longer transmission ratio thus serves to significantly reduce engine speed compared to a ‘standard’ 320d Saloon, benefiting fuel economy and emissions.
The new car still comes fitted with the existing suite of BMW EfficientDynamics technologies, including Auto Start Stop, Brake Energy Regeneration and Electric Power Steering for optimum performance, that have featured on all four-cylinder BMW 3 Series models since September 2007.
The BMW 320d EfficientDynamics Edition is the most fuel-efficient and lowest-emission car in BMW’s current model range. BMW is not charging a premium for the EfficientDynamics Edition; i.e., it is priced the same as the “regular” 320d.
In UK, the BMW 320d EfficientDynamics will cost just 35 pounds a year to tax courtesy of a Vehicle Excise Duty band B rank.
