I read that this morning too. They would be 13 litres short of a full race load on some tracks. How can someone design a highly thought out thing like an F1 car with all the aerodynamics, loadings etc and not work out the mpg.
Isnt it a rule now that they must also have 1 litre left in the tank after finishing for fuel tests.
