Here is was Karl Ludvigsen wrote about Ferraris '52 Indy attempt:
Alberto Ascari raced this big Ferrari once more in 1952 and at an unfamiliar venue: Indianapolis. With its 4 1/2-litre engine just right for Indy, the shrewd Enzo Ferrari succeeded in selling several cars to American racers. His cars' success in Mexico contributed strongly to their interest in buying a Ferrari. At the urging of his American agent Luigi Chinetti he also prepared a single entry to compete as a 'Ferrari Special' in the 500-mile race. Alberto Ascari underscored the exploratory nature of this Expedition in May 1952:
'The veni, vidl, vici of imperial memory is not part of my spiritual baggage,' he joked. 'lt seems to me I'm Christopher Columbus in miniature. I too am going to discover America. I'm going gladly, because I think that Indianapolis is an essential test for a good driver. lf my experience there gives favourable results, the next year we'II return with a real team; only then could we conjure with dreams of victory. For the moment I'm a pioneer, going to learn.'
At Ferrari the driving force behind the project was Aurelio Lampredi. He had much greater confidence in the effort than he would allow his driver to reveal. Reliability was not expected to be a problem; the car had easily coped with 300 hard testing miles at Monza. Nor was the driver considered a liability. Enthusiast John Cuccio was among those who interpreted for Alberto, whose English was limited to 'fine, fine'. Ascari easily passed his mandatory 'driver's test' and afterward pasted his three rookie-stripe tapes across the back of mechanic Stefano Meazza. 'When, at the conclusion of his tests, he was permitied some fast laps, wrote Speedway expert Russ Catlin, 'American onlookers, in general, declared him a polished driver. There is no doubt that had his own car failed he could have had his choice of at least a dozen top-flight American cars to drive.'
Speed turned out to be the challenge. The Ferraris were lapping the 2 1/2-mile track at no better than 132mph when the betting was that 135mph was needed to secure one of the 33 starting places. Testing was hampered by heavy rains during the week before the first qualifying weekend. More power was needed, and Lampredi thought he had the answer in Maranello. When he flew back from a quick visit his luggage contained a new inlet manifold with three four-barrel Weber carburettors. A bigger hood bulge was hammered out on the spot to make room for it.
'There were some truly great scenes to watch that year,' wrote Indy mechanic Clint Brawner. 'There was an Italian driver, Alberto Ascari, in a big ltalian car, a screaming 12-cylinder Ferrari, who was downshifting for the corners four times per lap, yet turning identical lap times in spite of it.' This was amazing to the Indy regulars, who shifted only when they left the pits. Ascari went down a gear going into the pair of turns at each end of the lozenge-shaped track. Even so, the Ferrari seemed to lack the propulsive thrust out of the turns that ihe American cars enjoyed.
Finally, late on the last qualifying Saturday, the red number 12 Ferrari attempted to lap fast enough to make the grid. 'There has never been a four-lap qualifying run quite like Ascari's,' wrote Russ Catlin. 'The phenomenal thing was that in spite of shifting on each turn, Ascari turned in four laps that differed only eight hundredths of a second between the fastest and slowest. The third and fourth laps were made in identical time: one minute seven seconds flat! A Ferrari was in the race!' The speed was nothing special - 134.31 mph in a field that averaged 135.50 - but it was süfficient. And Ascari's uncanny consistency created another legend of the Speedway. His successful qualification, with all the attendant Indy hoopla, 'was a very moving, unforgettable experience,' said Lampredi.
Ascari had reasons to hope for success. Unlike the Indy regulars, his crew had not used exotic fuels for qualifying, so his qualifying speed was also his potential race speed. Fuel economy was also an advantage. Before leaving Italy Ascari said he thought he could get through the 500 miles with only one stop for fuel. Instead tyre life was the limiting factor, so three stops were scheduled at 50-lap intervals to refuel and change tyres. 'The Americans were taking almost two minutes to refuel while we were taking 18 seconds,' said Lampredi. This would allow them to gain laps on the leaders.
'Alberto was to do the first section at 6,500 revs, then 6,500 again, then into the final offensive,' Lampredi added. 'So we thought we could win, with Alberto driving with his hands in his pockets. We were in for a surprise.' 'In the race I made the first laps at a reduced speed, wanting to study my opponents and the behaviour of our engine,' Ascari related. In Mexico he had competed against many of the leading American drivers, of whom he said, 'They are courageous and skilled, but they follow the theory "win or bust".' This could work in his favour at Indy.
Ascari: 'When I was persuaded I could throw myself forward, I accelerated from 21st up to seventh place.' Russ Catlin saw him make this move: 'The field was still bunched but, low and on the inside, came Ascari. He maneuvered past the field with a perfect exhibition of dirt-tracking. Some eyebrows were raised.' 'l now began to feel more at ease,' said the Ferrari driver, and to think that if bad luck did not pursue me, I might be able to arrive third or perhaps even second. I had already decided to wait for refuelling to make my offensive, when on lap 41 disaster struck.' After three-quarters of an hour of racing the hub of Alberto's right rear wire wheel fractured. lt broke partway between the splines that attach it and the rings of holes retaining the spokes. Feeling the wheel collapse in the fourth turn, he kept the red car under control as it swerved, veered into the infield and chuntered to a stop in the grass. Like Mauri Rose the year before, wire-wheel failure had stopped a contender, which was why most of the Indy regulars had already switched to magnesium wheels. 'He was out of the race,' wrote Catlin, 'but not until serving notice that he and his Ferrari are to be reckoned with, come another year. His performance, to this point, had been flawless.'
'He returned to the pits,' Lampredi related. 'He did not say a word for the rest of the race. Both our heads hung low that day, because we had had an easy victory in sight and we had lost our chance.' When he retired, before commencing his charge, Ascari had been averaging 128.71 mph; the race winner averaged 128.92 mph. Said American racing driver Sam Hanks, 'Ascari showed me enought in the 100 miles he lasted at the Indianapolis 500 to let me know he was equally at home on our speedway as on the road circuits of Europe. lf he hadn't broken that wheel I firmly believe he would have had a lot to say at the finish.'
He might well have been in with a chance. His precise, decisive and consistent style was made to order for the Speedway. Thus the dark-suited Alberto commanded respect at the prizegiving dinner out of all Proportion to the cheque for $1,983.19 with which he was presented for 31st place. That respect was underlined by the inscription on the back of an armband he was given by track officials: 'To Alberto Ascari - A Grand Guy'.
