The fuel efficiency of each Spaceships campervan depends on the campervan category. The fuel economy of each model is listed here as part of the specifications and features of our campervan fleet.
Roughly the average fuel economy is around 9 litres per 100km aka 1:11 but do check the stats for each vehicle category. Compare all campervans and their fuel economy.
Of course this also depends on many factors like the road you are driving on, wind speed / weather and your driving style. Make sure to also check our article about safe driving and driving in a more fuel-economic way.
