The sports sedan's BMW TwinPower Turbo diesel engines likewise incorporate the very latest in BMW engine technology. Latest-generation common rail direct injection, turbocharging and all-aluminium design provide these cutting-edge diesel engines with high torque, high levels of refinement and unsurpassed efficiency. A centrifugal pendulum absorber integrated in the dual-mass flywheel reduces irregular running for greater refinement at low engine speeds. In the sixth model generation, too, the BMW 320d EfficientDynamics Edition is the uncontested CO2 "champion" and again sets the benchmark in its segment, with average EU fuel consumption of 4.1 litres per 100 kilometres (68.9 mpg imp) and CO2 emissions of just 109 grams per kilometre. Also, from mid-2012, advanced BMW BluePerformance technology will be available for the new

BMW 320d and BMW 320d EfficientDynamics Edition. This system, which combines a diesel particulate filter and oxidation catalyst with a NOX adsorber catalyst, efficiently reduces nitrogen oxide emissions and achieves compliance with the EU6 standards.
