Top 10 Cars With The Highest Fuel Consumption Ever

I’ve based this selection not only on the fuel consumption as such, but also took into consideration more factors like the relation of the vehicle’s engine power to its fuel consumption and the overall recognition of the vehicle having an excessive fuel consumption (thus I didn’t include any American cars of the 1950s and 1960s as for them the fuel consumption was just a statistic without any meaning back then). Also I tried not to include multiple vehicles using the same engine family.
