Centenari

In 1991, Centenari built the M1, and entered Federico D'Amore in several Italian Prototype Championship events that year.

[2] For 1992, D'Amore left the team, and Stefano Speranza was entered at Monza, but failed to finish.

The team made its debut in the season opener at Donington Park, with Merzario and Giovanni Li Calzi hired as drivers, and won their class at the first attempt; as the only other SR2 class entry, a Didier Bonnet Racing-entered Debora LMP297-BMW, retired from the event.

[10] The entry for the final race at Jarama was made under the Centenari name once more, and the team took the SR2 class victory, and finished second overall.

The team started their season at the 1000 km Monza, which was part of the GT Italian Challenge and the Challenge Endurance Italia, with Loic Depailler, Xavier Pompidou, Giovanna Amati and Marco Lucchinelli driving the new Mac3, and Merzario, Giovanni Li Calzi, Robin Donovan and Fulvio Ballabio driving the older M1.

[19] Nürburgring saw a small improvement; the Mac3 and one M1 both finished, in twelfth and thirteenth overall; however, these were the bottom positions in the CN class.

[22] Centenari were classified joint-second in the CN Team's Championship, and eleventh overall, at the end of the season.
