For the Voiturettes test of the 1921 Italian Grand Prix, Bugatti has prepared five cars with the latest evolution of the multi-valve engine. The race starts at an unbridled pace with Friderich’s Type 13 leading the way, closely followed by Silvani’s SB and three other Bugatti. On lap 10 the leader suffered a puncture falling to fourth position and his teammate De Vizcaya took the lead, with Marco third and Baccoli fifth. The public watches a bitter duel between the speedy Bugatti, as the SB is soon forced to leave.
From Vizcaya, pursued by Friderich, he stomped and exceeded 120 km / h increasing his advantage to two minutes. But from the pits, Patron controls the whole situation: his strategy is to let De Vizcaya play the role of hare and reserve Friderich for the final round. Baccoli does not want to risk it either and lifts his foot off the gas in order to facilitate the comeback of the Alsatian, who is thrown after the head. Once in front, he will not leave the lead until the end, finishing in just under 3 hours at an average of 118 km / h, a record for the category.
From Vizcaya it is second to 1 minute and 18 seconds; 6 minutes later Baccioli enters and 3 after this Marco does, rounding out the overwhelming victory of the black cars.
The Brescia race becomes one of the most overwhelming demonstrations of power by the Molsheim firm and a full-blown defeat for the Italian car industry. Watch out for the media coverage Ettore Bugatti will baptize the Type 13 as “Brescia”, albeit in a sense This name is strictly applicable only to racing versions of the model produced thereafter.
