In July 2022, Squadra Corse named Caldarelli and Bortolotti as the first factory drivers for the SC63 prototype program.
Lamborghini's most ambitious motorsport project would be entrusted to the two drivers who defined its GT3 era, not to outside recruits with prototype pedigrees.
Mirko Bortolotti won both the Italian Formula 3 Championship and the FIA Formula 2 title before pivoting to GT racing, and by the time of the LMDh announcement he was leading the DTM championship at the season's halfway mark.
Andrea Caldarelli had won every race of the 2022 American season and carried firsthand knowledge of the Circuit de la Sarthe, making him and Bortolotti the institutional foundation Lamborghini chose over hired prototype speed.
