• Grid size: A total of 44 cars started the race, representing manufacturers such as Ferrari, Maserati, Porsche, and Gordini.
• Attendance: Over 100,000 spectators attended the event, highlighting the popularity of motorsport in post-war Argentina.
• Weather conditions: The race was run under dry but warm conditions, with temperatures reaching 32°C, challenging car cooling systems and driver endurance.

How It Works

The 1000 km Buenos Aires followed standard endurance racing protocols of the era, combining speed, strategy, and mechanical resilience over a long-distance format. Teams relied on co-driver pairings, pit stops for fuel and tires, and consistent lap times to maintain position.

• Endurance Format: The race lasted approximately 6 hours, requiring drivers to manage tire wear and engine stress over long stints.
• Co-Driving: Each car had two drivers who alternated during the race, with mandatory minimum driving times enforced.
• Pit Stops: Teams made 3–5 pit stops for refueling and tire changes, with average stop durations of 2–3 minutes.
• Refueling: Fuel tanks held 120 liters, requiring mid-race refills due to high consumption rates at full throttle.
• Tire Strategy: Teams used Avon and Dunlop tires, with soft compounds lasting 80–100 km before degradation.
• Scoring: Points contributed to the 1956 World Sportscar Championship, with first place earning 8 points for the manufacturer.
