Выбрал ещё несколько цитат из книг пятидесятых-шестидесятых годов. Первым упоминанием версии о решении ФИа по-прежнему является книга Джованни Лурани 1970 года. Вот полная подборка.
1953
Gregor Grant - Formula 2
FORMULA 2 racing, for cars of up to 500-c.c. supercharged, and 2,000-c.c. unsupercharged, became of major importance in 1952 when the organizers of the grandes epreuves abandoned the existing Formula 1 (1,500-c.c. S, and 4,500-c.c. U/s) in favour of the smaller category... France started the ball rolling by announcing that the eight Grands Prix of France in 1952 would be organized to Formula 2, and that these races would carry an extremely large amount of prize-money, both accumulative, and to be won at each event. Naturally this gave race organizers in other countries seriously to think. Switzerland tentatively announced that the Swiss G.P. would also be for Formula 2 cars, but Belgium stated that their G.P., which was also the Grand Prix of Europe, would be a Formula 1 affair...Almost immediately after Turin, the Belgians announced that the G.P. of Europe would be switched from Formula 1 to Formula 2. The B.R.D.C. confirmed that the Daily Express International Trophy at Silverstone would also be a Formula 2 affair, and later announced that the British Grand Prix would also be for cars of that category.
...
Suddenly Formula 2 racing was elevated to full Grand Prix status. The withdrawal of Alfa-Romeo from the grandes йpreuves, the failure of the B.R.M.s to fulfil their early promise, and the obsolescence of the Lago-Talbots made it obvious that organizers would have great difficulty in finding any sort of opposition for the 4J-litre, unsupercharged O.P. Ferraris. France started the ball rolling by announcing that, with the possible exception of Albi, her major Grand Prix events, including the G.P. de l'A.C. de F. (French G.P.) would be for Formula 2 machines. Millions of francs were offered to be won in the series, which would be held at Pau, Marseilles, Paris, Rheims, Rouen, Sables 1'Olonne, Comminges and La Baule. As everyone now knows, this wholesale switchover to Formula 2 had very far-reaching effects. Other countries eventually followed suit, and announced their grandes йpreuves would also be for Formula 2 machinery.
1956
Cecil Clutton, Cyril Posthumus, Denis Jenkinson - The Racing Car Development & Design
Continual domination by the Ferrari team, with a few assorted out-of-date cars added as make-weight, would tend to make the public lose interest in Grand Prix racing and cause a consequent financial loss to the clubs. With this situation in mind almost all the organisers changed the classification of their Grand Prix events to Formula II, and Grand Prix racing changed from a spectacle of speed and fury to one of comparative meekness though technical interest and inter-make rivalry increased enormously.
1958
Norman Smith - Case History
Tremendous and unexpected developments in Grand Prix racing regulations during the close season of 1951/52 effectively ended the Lago-Talbots big time racing career when Formula 2 succeeded Formula 1 as the main attraction, few race organisers having the spirit to remain true to Formula 1.
...
With an exact sense of dramatic timing the works allowed the G.P. at Barcelona to become their ‘Swan Song’ in Grand Prix racing and the withdrawal of the factory cars from the International classics unintentionally (but actually) reduced Formula 1 racing to such a possible farce that by 1952 it had been sabotaged in favour of Formula 2, and since that day when Fangio won the 1951 Spanish Grand Prix a ‘159’ Alfa has never turned a wheel in competition.
...
Numerous forecasts made late in 1951 regarding the possibilities of glorious Ferrari-Alfa-Romeo tussles in 1952 never materialised for the Formula 1 Grand Prix regulations were brilliantly sabotaged by a wholesale swing-over on the part of Continental race organisers to Formula 2, a situation that was both totally unforeseen and unexpected by many racing groups, including Britain’s B.R.M.
...
The demise of Formula 1 racing, by a combination of circumstances no one could really have foreseen, and the wholesale swing-over to Formula 2 for the majority of the 1952 World Championship schedule, left Maserati without a suitable machine for the new regulations.
1959
Cyril Posthumus - The British Competition Car
Alas, true raceworthiness was achieved too late, after Grand Prix organisers had switched en masse to Formula II (up to 2 litres unsupercharged) for 1952, leaving our over-lauded Grand Prix challenger to blare its always exciting but fruitless way round in isolated races to the old Formula I, and on various home circuits.
1962
Raymond Mays, Peter Roberts - B.R.M.
The French announced that their Grand Prix races for this season would be run under the then Formula Two, for which the more powerful B.R.M. was ineligible.
...
campaign failed and Formula One was virtually dead in 1952. Belgium, who were staging the Grand Prix of Europe, the Swiss and the Germans all staged their Grands Prix under Formula Two rules, while Alfa-Romeo, Simca and Talbot withdrew from Formula One racing.
1962
Rodney Walkerley - Racing Cars Today
In 1951 Alfa Romeo won four classic races, Ferrari three. The B.R.M. was still, unfortunately, not ready for serious racing. This had a profound effect on Formula 1 for, in 1952 Alfa Romeo again withdrew from racing, this time permanently, and with only Ferrari left against much weaker opposition, the big races were run under Formula 2, for the less powerful 2 litres which were, in fact, the forerunners of the present day cars.
1964
Duncan Hamilton - Touch Wood!
In 1952 I had a very full season's racing. I drove regularly for H.W.M., competing in most of the European Grands Prixs. This was the year promoters favoured Formula 2 cars for their International Meetings, for the withdrawal of Alfa-Romeo from Grand Prix racing had robbed Formula 1 of its attraction.
1965
Richard Hough & Michael Frostick - A history of the world's racing cars
AT the end of 1951 a most fruitful and enjoyable Grand Prix formula came to a premature conclusion. With the withdrawal of Alfa Romeo and the non-appearance of the it was hoped that more competition for the Ferraris would be obtained by running all major events to formula 2 (2-litre unsupercharged) regulations.
1970
Giovanni Lurani - History of the racing Car: Man and Machine
Increasingly, therefore, race organizers abandoned Formula 1 in favour of the 2-litre Formula 2, and when the BRM entry for the early-season Turin GP was withdrawn, Formula 1 to all intents and purposes collapsed, and the FIA agreed that the World Championship series would be for Formula 2 races.
1975
Denis Jenkinson and Cyril Posthumus
The international racing situation was a bit precarious at this time, for Alfa Romeo had withdrawn, the BRM looked as though it was never going to get off the ground, Maserati had dwindled and Simca-Gordini and Talbot were no match for Ferrari, so that Grand Prix events seemed like being a one-make benefit. In consequence most of the organisers of Grand Prix races opted out of Formula 1 and substituted Formula 2 events, there being no shortage of manufacturers interested in this 2-litre unsupercharged category. Ferrari himself had 12-cylinder and four-cylinder engined Formula 2 cars; Maserati were active, so were Gordini, Cooper, Connaught, HWM, Veritas and AFM. In a short space of time the World Championship Grand Prix events were changed to Formula 2 for 1952 and 1953 and the old Formula 1 cars were relegated to a few minor events.
1977
Wiliam Boddy, Brian Laban - The History of Motor Racing
So, Fi tended to take on a subdued aspect, in 1952, with only Ferrari ready to race his 4 1/2-litre cars. For this reason, many organisers took a look at the situation, with the V16 BRM still giving much trouble, and then decided to hold only Formula Two races, which attracted big and varied fields.
1980
Eric Dymock - The Guinness Guide to Grand Prix Motor Racing
When the BRM failed to appear for a non-championship Formula 1 race at Turin in April, national automobile clubs all over Europe decided on Formula 2 events.
1986
Adriano Cimarosti - The Camel Complete History of Grand Prix Motor Racing
In 1951 the FIA decided the Grand Prix I formula for the 1952 and 1953 World I Championships would be the 1948 Formula Two.
1987
Alan Henry, Alan Briton - Grand Prix
For 1952—3 the FIA changed the specification to Formula B (or Formula 2 as it came to be called) — a voiturette class for unblown 2-litre cars.
1991
Ivan Rendall - The Power and the Glory: A Century of Motor Racing
With Alfa out of racing and BRM not meeting expectations, Ferrari was the only team with a competitive car for the 1952 season. The World Championship was run using Formula Two cars.
1991
Anthony Pritchard - A Century of Grand Prix Motor Racing
Although the decision to run World Championship Grands Prix in 1952 to Formula 2 was made late, there was no shortage of contestants.
1992
John Surtees - Pirelli Album of Motor Racing Heroes
Then the sport’s governing body changed the rules. There were simply not enough Formula One cars. Alfa Romeo had withdrawn and BRM could not compete. In 1952 and 1953, therefore, the world championship was run according to Formula Two rules, with engines restricted to 2000 cc for unsupercharged cars or 500 cc for supercharged.
1993
Ivan Rendall - The Chequered Flag: 100 Years of Motor Racing
Promoters turned to Formula Two, which had been flourishing since 1948, and bowing to the inevitable the FIA agreed that for the 1953 and 1954 World Championship points would be awarded in Formula Two races.
