Does the alleged and actual fuel consumption of Mitsubishi ASX differs?

According to official data, cars consume 8 (engine 1.6), 9.8 (engine 1.8) and 10.5 (engine 2.0) liter of gasoline per 100 km, and on road 5, 6.4 and 6.8 respectively. The figures are reasonably close to real: the operation showed that the fuel consumption was greater than the stated consumption of not more than 0,5-0.7 litre.
