Evidence from Emissions Analytics reveals the difference between official fuel economy figures and real-world results is continuing to grow.
The latest examination of its data shows that the gap between the combined New European Driving Cycle figures and its real-world results has grown to 24%. This is a dramatic increase from the 16% average variance it first recorded in 2012, and shows the degree to which official figures distort the true picture of vehicle efficiency.
The company says that in real terms, the fuel economy motorists can expect from their new vehicles is hardly growing, at just 2mpg over the last three years. They say that these new results suggest progress in this area has now stalled.
Emissions Analytics also claims that any backlash against ‘dirty diesels’, as previously reported on, may further work against greenhouse gas reductions if consumers switch back to the higher CO2 gasoline vehicles, despite the fact that the industry narrative and public perception about diesels may be lagging reality.
