Criticising the Formula 1 fuel limit that teams have abide by, Renault Managing Director Cyril Abiteboul has claimed that it is taking the fun out of the sport.
Currently, the 1.6-litre V6 turbocharged hybrid system that teams are running is restricted to a fuel-flow rate of 100kg per hour and are not allowed to use more than 100kg of fuel during a GP.
Abiteboul also added that he fears that Formula 1 is leaning towards an endurance type of race rather than an exciting and attacking one.
"I am a big fan of making sure F1 remains F1. We should not lean towards endurance," he told autosport.com.
"One of the things that has put F1 in danger, or could be another threat to F1, is if we try to combine F1 and endurance.
"Endurance is about efficiency, sustainability, the capacity to run very long distances without any issues. F1 is about short races, usually being able to attack constantly.
"Frankly, even in the V8 era there was some fuel management. It was part of the tactics, to maximise, to optimise your laptime for the duration of the race from a team strategy perspective.
"It has always been part of F1, without any form of limitation on fuel quantity, so I would remove completely the fuel quantity [regulation]."
