BMW 320d EfficientDynamics Edition: state-of-the-art diesel engine makes the new sports sedan the most efficient vehicle in its class

Drivers who don't want to miss out on either dynamic, sporty performance or first-class fuel economy will find the new BMW 320d EfficientDynamics Edition an extremely attractive proposition. As in the previous model, this ultra-fuel-efficient version of the BMW TwinPower Turbo four-cylinder diesel engine represents the most radical realisation to date, in the sporty BMW 3-Series range, of BMW's development strategy for reducing fuel consumption and emissions.

The 2.0-litre 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 optimised 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/163 hp at 4,000 rpm and delivers its maximum torque of 380 Nm between 1,750 and 2,750 rpm. This sedan model accelerates from 0 to 100 km/h (62 mph) in just 8.0 seconds and hits a top speed of 230 km/h (143 mph). Fuel consumption of 4.1 litres per 100 kilometres (68.9 mpg imp), with corresponding CO2 emissions of 109 grams per kilometre, make this diesel model the most economical, eco-friendly and efficient vehicle in its segment.

The low-CO2 model also has something new for drivers who like to leave the shifting to an automatic transmission. The new BMW 320d EfficientDynamics Edition can now for the first time be combined with a cutting-edge eight-speed automatic transmission. What's more, this extra comfort doesn't come at the expense of higher fuel consumption. Thanks to efficient electronics and reduced-friction components, the engine can operate just as efficiently with the new unit as with the standard six-speed manual transmission.
