The series was open to Le Mans Prototypes and grand tourer-style racing cars meeting four ACO categories.

The calendar retains the eight rounds from 2015, but adds the 6 Hours of Mexico City at the Autódromo Hermanos Rodríguez.

The Nürburgring round has been moved a month forward to July to close the gap after Le Mans.

A single bonus point was awarded to the team and all drivers of the pole position car for each category in qualifying.

Furthermore, a race must complete three laps under green flag conditions in order for championship points to be awarded.
