The ACO announced new hybrid regulations for 2020, but has missed a golden opportunity to encourage new manufacturer participation in the future.
Rumours first circulated in the German magazine Motorsport Aktuell after the Le Mans test that Porsche will soon withdraw from LMP1 gathered momentum during race week and it now seems highly likely that the brand will leave to pursue a Formula E programme instead.

Even if that rumour out not to be true, both Peugeot and BMW have looked closely at the current regulations, and walked away on the grounds of cost and road relevance for the future.
Although great strides have been taken to reduce the cost of competition by around a third, Peugeot wants the new budget cut in half, and wants to see a reduction in hybrid energy stored. With neither addressed under these proposals, the hopes that Peugeot will come and join the party have pretty much evaporated.
A restriction of the aero development, with just one kit, reduced wind tunnel time (from 800 hours to 600 hours), and a change in hybrid deployment are the headline announcements. It is the last of these that will really cause the mischief. In a bid to make the hybrid deployment more relevant to road racing, each hybrid must complete 1km on EV energy alone during each stint. That must be done at racing speed, and it is here that the majority of the budget will need to be spent in the early days. It is for this reason that there is no reduction in hybrid energy storage; the FIA c...
