Refuelling returned to the agenda of Formula 1's chattering classes last week thanks to a combination of FIA president Jean Todt's suggestion that such a move should be analysed and support for this from the Grand Prix Drivers' Association.
But while refuelling is not without its positives, for the drivers in particular it would be a mistake for grand prix racing to go back there. The arguments in favour are that it would allow drivers to push more during races, a laudable aim, and would help reverse the trend of modern GP cars becoming increasingly bloated.
It would also introduce a new strategic variable that, so the argument goes, would make the races more interesting. Cars would indeed spend far more of the race closer to their ultimate lap times and the space saved by not requiring a fuel cell to lug 105kg around should also confer a small car-size gain because the fuel tank would be smaller.
