You may wonder if this is a joke...well it isn’t! It is true! The 2.0 liter diesel engine of the Bmw showed better fuel economy than the well-known eco-friendly Toyota Prius. Some of you may see this camparison between the two cars ridiculous but if we look at the CO2 emissions of the two vehicles we see that there are almost equal: the Bmw delivers 41.9 mpg while the Prius, with almost 250 kg lighter, delivers 40.1 mpg.

The test between the two cars was made on the London-to-Geneva route. The Bmw equipped with a series of energy-saving features like the battery recharge when braking, good aerodynamics, low rolling resistance in a word the so-called EfficientDynamics showed no problems on the road and by the end of it also remained with a third of its tank in reserve.

The Prius ran out of gas but this happened only due to smaller tank and because the car is made for urban live. The advantage if hybrids can’t be seen on highway where the car is pushing through the wind, this can easily be seen in urban driving where the stop-and-go recaptures the car's energy.

Now if we make a conclusion we can say that Bmw showed every one that its 5-series can beat also the eco-friendly Prius but what if the test would have been made inside a town...Would the Bmw be the winner?
