On Sunday, June 11th, 1950, the IX motorsport Grand Prix is hosted in Rome on the difficult circuit of the springs of Caracalla. On the 40th lap Alberto Ascari is continuing to lead the rest of the field, as he had from the start, gradually increasing his advantage; the crowd awaits in vain for the #14, the british Moss on a HWM, to pass in front of the stands. His previous passage received a warm applause, as the young british driver (not yet 20 years of age), after a 30 lap duel with Villoresi on the Ferrari, managed to pass the rival. The british driver has already become a crowd favourite due to his fearless bravery: he slides a bit on the corners, giving the spectators a bit of a fright, but he shows to be safe and fast. He had shown this on the 18th lap, when he had beaten the lap record with a time of 1'59” at the average speed of 104.073 km/h. Moss' failing to pass on the finish line, just as Villoresi stops in the pits for about a minute due to gearbox issues, causes some apprehension; right after the speaker announces that the #14 had an accident that caused him to retire from the race, but that the driver is unharmed. Half an hour later, welcomed by a roaring appplause, Moss arrives on foot at the start/finish line and specifies the details of the crash: at turn 3, right behind the springs, the right front wheel sunddenly detatched from the car due to a broken axle. The wheel, travelling at over 100 km/h, went flying up in the air and past a stand of pine, and ended up in a place luckily not occupied by spectators. The silver car spun around, went sideways across the track and ended up on the grass. The ability and the cool head of the driver, that never lost control of the car, managed to avoid any harm to people. With Moss out of the fight, the race becomes boring: Ascari continues on in the lead without any worry and manages to lap every competitor besides Villoresi who, despite the lower speed of his car, manages to keep a few hundred meters advantage on his charging teammate. Both the organisation by the ACI of Rome and the enormous crowd attendance, favored by the summer day, are perfect.
On Sunday, June 18th, 1950, the 5th round of the World Championship is held at the circuit of Spa. In the standings Giuseppe Farina leads with 18 points, followed by Fagioli (12), Fangio (9), Ascari, Holland, Rosier (6), and other drivers. The driver from Turin will try to consolidate his advantage and at the same time grasp a very important affirmation. For the first time his Alfa Romeo 158 and those of his teammates will have to face a very serious commitment. If the expectations will not be changed by the race the brand new Ferrari 2000 of Villoresi, along with the 1500 of Ascari, could be a serious hindrance to the success of the Alfa Romeos. The most uncertain fight is between the driver of the same team, Farina and Fangio. For sunday a very intense race is expected. The popularity of the sport in Belgium means that a large influx of people will be present at trackside. Two weeks after the Swiss round of the Championship, the main contenders regroup at Spa-Francorchamps for the Belgian Grand Prix. Farina has come off the back bone of his second win of the season, allowing him to extend his Championship lead with 18 points. Teammate Fagioli is now second in the standings, his relative consistency putting him on 12 points, the elder Alfa driver has still yet to claim his first win. After a non-finish at Bremgarten, Fangio has dropped to third in the Championship standings, he has won in Monaco but two non-finishes have hurt his chances. It was a painful loss in Switzerland, after dominating the weekend, Fangio had lost the race with six laps to go when he was forced to retire with engine trouble. With only three rounds left in the Championship, the title looks like it will be awarded to one of the three Alfa Romeo drivers, however the Ferrari cars are still in for a distant shot at the title. Alberto Ascari sits on six points, however a non-finish at Bremgarten has seriously dented his chances. Nonetheless, Ferrari debuts the new non-supercharge Ferrari 275, the successor to the 125 for Belgium. Aurelio Lampredi's first Ferrari design will hopefully be the car prepared to topple the Alfa domination.
Ascari closest on points to the Alfa's in the Championship is given the opportunity to race the new car at Spa. His teammate, Luigi Villoresi have had a dreadful start to the season, he has yet to score a point due to poor reliability despite a series of competitive runs. Notably, Ferrari's third driver, Raymond Sommer, has left the team following the Swiss race. Sommer, famous for his lack of commitment to a racing team has returned to his old ways of competing as a privateer. Sommer has regained his independence after two years with Ferrari, he will continue to compete in a private Talbot-Lago T26C, the car albeit is not as fast as the Ferrari's he has been driving. The Talbot-Lago's will in fact make up the majority of the field in Belgium, the works team will field Yves Giraud-Cabantous and Louis Rosier as usual. Rosier is the one driver on the grid who has previously won the Belgian Grand Prix, taking victory last year. Rosier has been the quiet achiever of the season, his six points mean he remains in with a title chance. After Eugene Martin sustained serious injuries following his Bremgarten crash, the team has subsequently called on Philippe Étancelin, previously dropped from the outfit to return as his replacement. The works entry also enter a car for Pierre Levegh who has raced as a private entry in Bremgarten. The final Talbot-Lago entries are the private entries of Johnny Claes and Eugène Chaboud. Chaboud making his Championship debut in Belgium. There is a notable lack of absence of Maseratis in Belgium. The works Maserati team has taken a break from the Championship whilst secondary team of Enrico Plate are away competing in the British Empire Trophy, non-championship Formula 1 race. The only Maserati entry comes from, Antonio Branca, racing his heavily outdated 4CL chassis. Most of the British representation are absent to compete in their local British Empire Trophy event, however the little Alta of Geoffrey Crossley has ventured to Belgium as a lone British competitor. The Alta has previously competed at the opening round of the Championship at Silverstone with little success.
