It became obvious during Friday practice sessions that the race would be between the Ferraris and Lancias. The Lancia D24s lapped the 5.2 mile circuit in three minutes 38 seconds and on the Saturday, Cunningham's Ferrari 375 MM made it in 3m 31sec. Another of Cunningham cars, an Osca MT4 1450 piloted by young English driver, Stirling Moss with his partnered Bill Lloyd, turned in lap on Friday of, 3m 56 secs, although this small engined car, no one considered this car a real threat the Lancias.
Race
The race was held over 12 hours on the 5.2 miles Sebring International Raceway. The early morning rain cleared to leave a cold, windy but dry day. However, throughout the race, the strong wind blowing directly out of the north created a nasty crosswind on the fast back stretch. With the race starting promptly at 10am, 59 cars scrambled for positions. Cunningham in his own Cunningham-Chrysler C4R was the first across the line, but was soon headed by Erwin Goldschmidt in his Allard-Cadillac J2R. However, before the end of lap one, the three Lancias, of Fangio, Ascari and Taruffi had sorted themselves out and headed the field, running one, two and three with Spear's Ferrari close behind. The Cunningham Ferrari of Phil Walters, stopped for a replacement spark plug and lost several minutes. Moss was keeping the bigger cars on their toes holding down 4th. Around mid-distance, trouble hits Spear's Ferrari, crippled by a broken oil seal. Last year's winner's, John Fitch and Walters, in their Ferrari had been marking up time, and with Spear's retirement, the only threat to the flying Lancias. Fitch and Walters had been pushing the car hard, and this too would not finish, going out late afternoon with a bad connecting rod bearing. As darkness fell on the former Hendricks Army Airfield, the Lancias of Ascari and Villoresi, and Fangio and Castellotti had retired due to brakes and gearbox issues respectively, leaving the burden on the shoulders of Taruffi and Manzon. This D24, was still lapping swiftly on the now night-blackened circuit, at an average speed of 82 mph – more than seven mph faster than the 1953 record-breaking Cunningham C4R – albeit with only one headlight. As Taruffi and Manzon streaked out of sight, chief race steward, Alec Ulmann announced that the Lancia would be black-flagged if it continued to race with just one light. The team's race director, Attilio Pasquarelli put out a red flag, and leaned far out onto the course to block the car's path. When the car finally pitted, Manzon protested: “The car wouldn’t go any faster – oil pressure was off”. He thought the red flag was a pit signal that their lead was in danger. Despite, as Moss said, the Lancias were “wiping the floor with the rest of us”, Lloyd and Moss soon took advantage of the Osca's beautiful handling, by throwing the car sideways, into the corners to scrub off as much speed as they started to countering the high brake wear. The three Aston Martins had retired quite early and the leading Lancia D24 being driven by Manzon, stopped on the circuit with engine trouble an hour from the end of the race. Manzon returned to the pits on foot, but co-driver Taruffi acted to push the car for the mile and a half back to the pits. The Lancia was finally pushed across the finish line but was disqualified and the Osca, driven by Moss and Lloyd, won the race. The Osca survived a slightly suspect clutch and a tremendous rain storm to take a totally unexpected win. They covered 168 laps, averaging a speed of 72.800 mph. Second place went to the Lancia D24 of Porfirio Rubirosa and Gino Valenzano, albeit five laps adrift. Third place was awarded to the Austin-Healey 100 entered by Donald Healey and driven by Lance Macklin and George Huntoon. Although there were no fatalities during the race, James Brundage, died in Fort Lauderdale, Florida on his way home when the Allard he was driving hit a tree.
