The 520d ED will achieve the feat of being clean, green and mean at the same time by employing some clever tech. BMW have made the final drive ratio quite tall to enable the new 520d ED to cruise at the maximum possible efficiency on the open freeways. The new alloys comprise of a design which reduces drag significantly. The tyres on the new car have much less rolling resistance than normal. In addition to all this the car comes with a start stop system which saves fuel when the car is idling. The 520d ED also has a optimum gearshift indicator to help the driver stay in the best gear for best efficiency.
The car will be introduced in the European market by September. An Indian launch should follow in a couple of months.
