BMW is to offer the most fuel efficient and greenest 3 Series ever with the European introduction of the new BMW 320d EfficientDynamics Sedan. The latest model sets a new benchmark in the premium segment by recording impressive CO2 emissions of 109g/km and a combined consumption figure of 68.9mpg (Imperial).
The new BMW 320d EfficientDynamics Saloon is powered by a 1995cc engine with class-leading performance figures. The single-turbo diesel powerplant features an 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 develops 163hp between 3500-4200rpm and 265 lb-ft of torque from 1750-3000rpm. This equates to 0-62mph in 8.2 seconds and a top speed of 137mph. The heightened performance of the BMW 320d EfficientDynamics Sedan has been made possible due to changes to the engine construction, a longer final drive ratio, lowered suspension and the use of specially designed aerodynamic wheels with Michelin EnergySaver tires.
The engine also has a dual-mass flywheel with springs between the two parts to smooth out engine vibration through the drivetrain. This is enhanced with new Centrifugal Pendulum Absorbers to further improve smoothness. The 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 `regular 320d Sedan, 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, which has been featured on all four-cylinder BMW 3 Series in Europe since September 2007. The BMW 320d EfficientDynamics Sedan will be unveiled at the Frankfurt Auto Show in September and go on sale in January, 2010.
