The privateer LMP1 teams are to allowed to use a drag reduction system, similar to the current version used in Formula One, from the 2018 WEC season. The proposal, announced at the ACO's (Automobile Club de l'Ouest) press conference on Thursday ahead of this weekend's 24 Hours of Le Mans has been introduced in an attempt to close the gap between the current privateers and the manufacturers, as well as in an attempt to encourage more teams to join Rebellion and ByKolles. Whilst the decision is yet to be officially confirmed, it is understood that only the technicalities of introducing the system are yet to be finally decided, whilst the idea in principle is already well underway and being readily accepted. The move to DRS will mark the end of a two year program for the evolution of the Privateer LMP1 class, with both Rebellion and ByKolles set to use a larger rear wing from next season alongside a weight reduction of 28kg and the removal of the engine capacity limit and the number of engines they can use per season. Whilst having divided opinion amongst some fans of the sport, the move has come as a result of the increase in the gap between the privateer teams and the manufacturers, with lap times at Le Man having increased between the two by roughly 5 seconds since 2011.
