The LMP1 category in the World Endurance Championship will be given a refresher after the ACO, in conjunction with the FIA, announced alterations in technical regulations with focus on aerodynamic changes, while the privateer teams are expected to be allowed a DRS system in a bid to close the gap to manufacturer entries.

The new regulations, which are set to be confirmed after the Le Mans weekend, will enable LMP1 hybrid teams to raise its front splitter while the changes to the privateer teams are much more radical in a bid to attract more teams to the competition.

Currently there are just three cars entered into the LMP1 privateer category, two from Rebellion Racing and one from ByKolles Racing, while Strakka Racing is plotting a move up to LMP1 for 2017.
