The team, which has been a frontrunner in the French GT4 series, made its debut in the GT4 European Series last season, running Beltoise and Loris Cabirou to three podium finishes and seventh in the championship points.
For this year Beltoise (31) teams up with Alpine Europa Cup graduate Herrero (19) aboard the #29 Alpine.
Beltoise brings huge racing experience, having competed in series such as the European Le Mans Series, Porsche Carrera Cup and VdeV Endurance Series before joining the Mirage team for GT4 campaigns in recent years.
Herrero steps up to the GT4 European Series for the first time this year, having spent the last two years racing successfully in the single-make Alpine Europa Cup, scoring multiple race wins and finishing third in the overall points back in 2019.
