The Mercedes Benz 1955 1,2; Fangio and Moss in W196, 22 May 1955…
Mercedes had three 1/2 finishes for the year; at Spa and Zandvoort when Fangio led Moss and at Aintree where Moss led Fangio. At Monaco things were looking good for another but JM’s car broke a rear axle on lap 49 and Moss had an engine failure in the closing laps of the race (lap 80 of 100).
Maurice Trintignant (above) took a somewhat lucky, but well deserved win in his Ferrari 625 from Eugenio Castellotti’s Lancia D50, the Italian putting in a charge in the final stages of the race trying to catch the Frenchman.

This was the famous race in which Alberto Ascari crashed his Lancia D50 into the harbour perhaps distracted by Moss’ engine problems in front of him late in the race. He popped to the surface unharmed but was killed several days later testing a Ferrari sportscar at Monza.
It was a pivotal time in the history of GP racing; Ascari’s death robbed Lancia of the driver around which its GP campaign was built and Gianni Lancia’s lavish race program was quickly driving his company into insolvency.
The famous ‘handover’ of Lancia assets to Ferrari occurred later in the year, solving Enzo’s immediate need of competitive cars. The ‘sponsorship’ in the form of an annual contribution to the Scuderia’s budget from Fiat laid the foundations of a strategic partnership which, via ownership of the road-car division from 1969 and ultimate acquisition of the company upon Enzo Ferrari’s death continues today.
