The maximum amount of fuel that a Formula 1 driver can use over a race distance rises from 105 kilograms to 110kg in 2019, in a move that appears to contradict the ethos that efficiency is a cornerstone of the current hybrid regulations. So how did this change come about, and will it really make any difference?

For the first three years of the hybrid era the fuel limit was 100kg. Then in the build-up to 2017's big regulation changes it was realised that draggier, wide-track cars, with their high downforce levels allowing drivers to stay on the throttle longer, would impact consumption - so it was wisely decided to increase that to 105kg for '17. Despite the engine manufacturers continuing to explore the limits of efficiency that limit goes up by another five 5kg in '19.
