Just read today morning that all cars in UAE will have below efficiency rating mandatory from 2017. This new move seems very good for educating consumer before buying the vehicle, however I am not understanding the need of creating 5 levels of rating within just 1 L/100 km (1.71 km/liter) difference.
All cars that I have ever own falls much below the "Very Poor" rating.

14.2 km/liter (7.04 L/100 km) = Very Good
13.6 km/liter (7.35 L/100 km) = Good
13 km/liter (7.69 L/100 km) = Average
12.5 km/liter (8 L/100 km) = Poor
12.49 km/liter (8.006 L/100 km) = Very Poor
