Meanwhile, Officine Alfieri Maserati was represented a four different cars, across five entries. The remaining bulk of the field, were cars from South American teams.

Unlike the previous 1000 km Buenos Aires races, the Automóvil Club Argentino decided the race should take place at a different venue, instead of the Autódromo Municipal-Avenida Paz. They choose the Circuito de la Costanera Norte, which used the wide service roads of the Aeroparque Jorge Newbery. The reason for the change was that need to move to a “safer” track.

Jean Behra appears next in sixth. At the end of lap one, Castellotti pits with differential problems and loses more than seven minutes, and hands the car over to Luigi Musso. During the second lap, the Maserati 300S of Oscar Cabalén skidded off the track and into the crowd, causing numerous injuries.

At the end of the third lap, Collins retired his Ferrari 290 S with dangerously low oil pressure, meanwhile, Moss was marching way at the head of field, now being followed by Gregory, de Portago and Behra.
