Changes to the European Le Mans Series sporting regulations for 2019 see a ban on allowing teams to refuel their cars and change wheels at the same time, GTE-AM will be subject to success ballast, temporary dispensation from the rule on driver lineup composition, based on FIA driver ratings, has been taken away and the top two entries in the LMP2 standings at the end of the year will receive automatic invitations to the 24 Hours of Le Mans in 2020.

Following a rue change in 2018 to allow teams to perform both refuelling and tyre changes simultaneously in 2018, this action will now be abolished after the trial season.

In the move increase competitiveness in the GTE AM category, additional weight will be added to cars based upon previous race results and championship positions, with a maximum penalty of 45 kg available.
The cars that finish first, second and third will be required to run with 15, 10 and five kilos of extra weight at the next two events.
The same amounts will also be issued to the top three cars in the championship standings going into each race weekend.
Total success ballast will be calculated on an A+B+C formula where A equals results from the previous race, B equals results from the race before that, and C equals points positions.

The driver lineup dispensation has been removed after the controversy surrounding the #26 G-Drive Racing entry’s request to run an all-professional crew in 2018. The TDS-run operation agreed to adjust its driver lineup before the season started by including a Silver-rated driver in Andrea Pizzitola, who went on to win the LMP2 title with Roman Rusinov. 

Finally, bringing the series in line with AsLMS the top two entries in the LMP2 standings at the end of the year will receive automatic invitations to the 24 Hours of Le Mans in 2020, previously the invite was only extended to the winner.
