This BMW 320d EfficientDynamics is the cleanest, greenest, most fuel-efficient 3-series ever. It’s designed to appeal to fleet buyers and the environmentally conscious alike, and thanks to some further tuning and tweaking of the company’s biggest selling Three, the 320d EfficientDynamics will, on paper at least, achieve 68.9mpg and emit a remarkable 109g/km.
BMW first revealed its eco-friendly Efficient Dynamics technology in 2007, every manual 320d that’s emerged from Munich’s factories has been fitted with active aero, low-rolling resistance tyres, a gearshift indicator, an intelligent alternator and a stop/start system. In fact, every four-cylinder Three with a manual ‘box has come so equipped.
But there’s now a new version. So far the Efficient Dynamics tech has all been standard and relatively under-the-radar (whereas Mercedes badges all its latest models BlueEfficiency) but BMW has now come up with an even cleaner 3-series. It’s the company’s special eco model, with extra tweaks to make it even greener and save you money with its startling CO2 output.
