[1][2] A total of 87 racing cars were registered for this event, of which 70 arrived for practice, to qualify for the 60 places on the starting grid, and included 15 factory teams.
[3] The battle between Coventry and Maranello of the previous year was joined by Mercedes-Benz, fresh from a triumphant debut in the Mille Miglia with their new 300SLR, along with dark horses Cunningham, Aston Martin and Maserati, all with new 3-litre cars, as well as Talbot, Gordini, Cooper, and Austin-Healey.
[2][4] The works team mixed its current F1 drivers along with new talent: Eugenio Castellotti with Paolo Marzotto, Maurice Trintignant with Harry Schell and Umberto Maglioli drove with Phil Hill.
[10] The team consisted of 1953 winners Tony Rolt and Duncan Hamilton; up-and-coming English star Mike Hawthorn (stolen from Ferrari) paired with rookie Ivor Bueb; and Jaguar test driver Norman Dewis sharing the third car with Don Beauman.
Cunningham hedged his bets this year – along with the Jaguar he loaned 750 Monzas to French privateer Michel Pobejersky (racing as "Mike Sparken") and American Masten Gregory.
Louis Rosier's privateer Talbot did not make the start, so the large-engined French challenge this year came from Gordini with a 3-litre T24S for F1 drivers Jean Behra and Élie Bayol.
[12] Aston Martin pared back its effort a bit, to just three DB3S (now with disc brakes and an improved 225 bhp (168 kW) 3-litre engine[13]).
[12] Colin Chapman, racing with Scotsman Ron Flockhart arrived with his new Lotus 9 sports car – like the other small English firms Kieft, Cooper and Arnott, running the 1100cc Climax engine.
Perhaps the most unusual entry was the tiny catamaran-style Damolnar Bisiluro from Ufficine Nardi – where the driver sat in one boom and the engine and running gear was in the other.
But there were also a number of serious accidents during practice: Moss was leaving the pits just as the DB-Panhard of Claude Storez came in, the small car hit Jean Behra.
While both cars were able to start the race, Behra had face and leg injuries that forced him out, to be replaced by reserve driver Robert Manzon.
[16] Coming into Maison Blanche, Behra's erstwhile teammate Élie Bayol in the new Gordini T24S came upon two spectators crossing the track.
He swerved and rolled the car and was taken to hospital with a fractured skull and broken vertebrae; Peter Taylor was also severely injured when he crashed the new Arnott.
[17] Neubauer tried, unsuccessfully, to persuade the ACO to allow him to erect a small signalling tower at the top of pit-line for his team.
[22] It was Castellotti, by dint of being near the front of the grid formation, who was first under the Dunlop Bridge and leading the first lap, followed by Hawthorn in the Jaguar.
Fangio's start was delayed when his trouser leg snagged on the gear shift lever, but he worked his way up the field to join Hawthorn and Castellotti.
Then thirteen minutes later, the MG of Dick Jacobs lost control exiting Maison Blanche, rolled and landed upside-down, burning.
[33] After the catastrophic accident, John Fitch, picking up on the early media reports, had urged the Mercedes team to withdraw from the race – he could see that win or lose, it would be a PR disaster for the company.
After an emergency meeting of the company directors in Stuttgart, Neubauer finally got the call approving the team's withdrawal just before midnight.
Chapman quickly reversed and got going again only to be disqualified because he had restarted without the marshal's permission[2][35] The Aston Martins had been running to a strict lap-time set by team manager John Wyer, but keeping just in the top-10.
[13] Soon after the Mercedes-Benz team withdrawal, the last Ferrari (that of Trintignant / Schell) retired with engine trouble, having fought back up to 10th position.
Further back, third in class, was the Belgian-entered Porsche (giving a first Le Mans drive to future endurance great Olivier Gendebien) Dawn broke under a heavy, overcast sky and by 6am it had started to rain.
[36] About the same time the Cunningham also retired: never in the running, lapping in 13th behind the smaller Porsches and Bristols, it had lost its lower gears the night before.
The podium was completed by the Belgian pair of Johnny Claes and Jacques Swaters, in their yellow Ecurie Francorchamps Jaguar D-Type.
Additionally the privateer Porsche comprehensively won the S-1100 class finishing nearly 40 laps ahead of the unclassified Cooper.
The three-car Bristol team finished seventh, eighth and ninth, in formation for a consecutive year at the top of two-litre class.
Less than three months later, Lance Macklin decided to retire after being involved in a twin fatality accident during the 1955 RAC Tourist Trophy race at Dundrod Circuit.
[43] The official enquiry concluded that no one driver was to blame and that it was instead a tragic combination of circumstances that had caused the accident, including serious deficiencies in the track design and safety.
[44] On the same day, the ACO announced their intent to hold the Le Mans race in 1956, and to make modifications to the Circuit de la Sarthe as necessary to adhere to the Ministry's new regulations.
[clarification needed] Taken from Quentin Spurring's book, officially licensed by the ACO Championship points were awarded for the first six places in each race in the order of 8-6-4-3-2-1.
