8 Reasons Why Your Vehicle Will NEVER Reach Its Claimed MPG

8 REASONS WHY YOUR VEHICLE WILL NEVER REACH ITS CLAIMED MPG!!! E Level of NEDC test discrepancies NIB EUD RVP STP FTR ТР AD AL New European Driving Cycle The NEDC is designed to test fuel economy in passenger cars throughout Europe e What it all means? RATING Currently there is no official body in place to police the testing procedure and monitor the results taken from the No Independent Body different labs. Tests conducted include simulating in town (urban) and out of town (extra urban) driving conditions, reaching a top speed of 75mph for 10 seconds. It does not included sustained motorway driving, where many cars consume the most amount of fuel. Urban & Extra Urban Driving Removing roof rails, extra lights and even the passenger door mirror is permitted. Making the car lighter results in a more impressive mpg figure. Removal of Vehicle Parts The same test procedure is followed by all manufacturers, however, they can pick from any credited lab to do the tests. The issue here, how is it Same Test Procedure o possible to compare results from multiple labs using different equipment? The rule allows vehicle makers to arbitrarily knock 4% off the results at the end. Fiddling the Results No restriction in tyre pressure. Higher-than- recommended pressures may be used to reduce rolling resistance, taking load off the engine and reducing fuel usage. Tyre Pressure Modern vehicles are being introduced with adaptable driving modes, such as an 'eco mode' for fuel efficient driving. Manufacturers have the option to elect 'eco mode' rather than the default settings of the vehicle for more impressive mpg. Adaptable Driving Tests are conducted with all auxiliary modes such as air conditioning, lights, heated windows, heated seat, radio etc turned off. This results in further impressive mpg figures. Auxillary Loads L Closer to the facts Drivers are on average spending £133 / €183 more per year on fuel. 98% of vehicles £133 / €183 do not match their claimed MPG. 98% 30% Take 30% off claimed MPG to calculate actual MPG of vehicle. C Conclusion Finland Norway Sweden UK Poland Germany France Italy Spain New European Driving Cycle The NEDC test which defines the official mpg figures – the ones carmakers have to show on in their marketing to conform to the relevant regulations, is outdated and no longer fit-for-purpose. The bare bones of the test have been used since the 1970s, was last updated in 1997, doesn't account for modern engine technology such as hybrid power, and does a poor job on reflecting real-world driving conditions. That's why Which? ( is now calling for it to be replaced with a better test in 2017, as scheduled, rather than being delayed until 2020. "The NEDC was last updated back in 1997 " Sources: NIB EUD RVP STP FTR AD AL
