The New European Driving Cycle (NEDC) is under more scrutiny for having a test cycle that simply does not replicate real life driving conditions. Vehicle manufacturers are claiming mpg figures up to 30% more efficient than they really are. Not only that, the NEDC has so many loopholes, it provides the opportunity for those manufacturers to manipulate the results, such as testing prototype vehicles which are not the same as the ones that go on production, taping up areas of the vehicle for more aerodynamics and over-inflating tires for less roll resistance. Some criticize and say that as a result, this does not encourage manufacturers in making more fuel efficient cars, as they know they will get away with being branded as fuel efficient, when in fact they are not.
In this infographic, we demonstrate the NEDC loopholes and compare the difference from real life conditions. We are only happy that the time is coming that this test will eventually be replace with Worldwide Harmonized Light Vehicles Test Procedure (WLTP).
