Next month at the Frankfurt Motor Show, BMW will be rolling out an extra high mileage Efficient Dynamics Edition of its 320d sedan. Like most European BMWs, this one is powered by a diesel engine that helps it get to 57.36 mpg (U.S.) on the EU combined driving cycle with CO2 emissions of just 109 g/km. This new edition of the 320d gets a number of optimizations to reach these lofty numbers. Under the hood is the mid-range 163 hp single turbo version of BMW’s 2.0-liter four cylinder diesel. It sends power through a 6-speed manual transmission and the ED edition gets a taller final drive ratio.
It takes less effort to move this 3-series through the air as the body has been lowered and new low drag wheels are fitted, bringing the drag coefficient down to 0.26. Parasitic losses are reduced through the use brake energy regeneration and electric power steering. Even with all the attention to efficiency, the 320d still gets to 62 mph in a very respectable 8.2 seconds. Perhaps if Munich offered up this model to Americans, in addition to the 335d, the company might have more success with diesel vehicles here.
