The 100Kg (37 U.S. Gallon) limit on fuel used per race is going to be a tough one. People who are pushing hard throughout the race will likely run out of fuel. Or, you will see someone leading, who will have to let off the gas pedal to complete the race and get some points. This forces the cars to meet 5 mpg at all races except Monaco, which is only 265 km instead of the usual 305 km.
