Race of Two Worlds

From Wikipedia, the free encyclopedia

The Race of Two Worlds, also known as the 500 Miglia di Monza (500 Miles of Monza), was an automobile race held at the Autodromo Nazionale Monza, Italy in 1957 and again in 1958. It was intended as an exhibition event, allowing American teams from the United States Auto Club (USAC) National Championship to compete directly against teams from the Formula One World Championship based in Europe. The two types of cars competed on the banked oval at Monza which had been completed in 1955. Due to the similarity to the Indianapolis Motor Speedway, where the USAC teams ran the Indianapolis 500, the event earned the nickname Monzanapolis.

American drivers and teams won the event in both the years in which it was run. Jimmy Bryan won the 1957 event, while Jim Rathmann swept the 1958 race. Although some Formula One teams did participate and even built special cars specifically for the event, several withdrew over safety concerns. Continued concern over the speeds on the track and the cost of the event led to the race being canceled after the 1958 running.

[edit] Initial concept

In 1954, redevelopment of the Autodromo Nazionale Monza circuit began for the first time since 1948, concentrating on rebuilding the oval portion of the track which had been abandoned during World War II. The 4.5 kilometre banked oval, which had last been used in 1933, was dismantled. The southern Sud Alta Velocita corner was relocated, moving it northward by several meters, shortening the lap distance length to 4.25 km. Both banked corners were rebuilt on a curving gradient, replacing the flat banking which had been previously used. The reconstruction was completed in August 1955, in time for the Formula One Italian Grand Prix, which combined the new oval with the Monza road course for a full 9.8 km lap.

The following year, Giuseppe Bacciagaluppi, then president of the Automobile Club of Milan, invited Duane Carter, competition director of USAC, to attend the second running of the Italian Grand Prix on the new circuit. The two discussed the similarities between Monza's new oval and the Indianapolis Motor Speedway, which also held a round of the Formula One World Championship, the Indianapolis 500. Although the 500 counted as part of the championship, the only European to participate in the event since the formation of the World Championship was Alberto Ascari in a Ferrari in 1952. Bacciagaluppi and Carter believed that an oval race held in Europe instead of the United States could attract Formula One teams, and USAC and the Automobile Club of Italy began work on making such an event possible.

An exhibition race was scheduled for June 1957, running just the 4.25 km oval at Monza. Volunteering USAC teams were to be transported from the United States, while Formula One teams were also free to participate if those chose. In preparation, Firestone Tire and Rubber Company transported a USAC Kurtis Kraft-Chrysler to Monza in April of 1957 in order to conduct tests on tires made for the event. American driver Pat O'Connor completed 226 miles on the oval, setting a best lap speed of 170 mph, nearly 30 mph faster than lap speeds reached at Indianapolis.

[edit] Format

The rules for the race were based on those used by USAC in North America. Engines were limited to 4200 cubic centimetres in naturally-aspirated form, 2800 cc for supercharged engines. An USAC rolling start was also used, instead of Formula One's usual standing start. The race was planned for a total distance of 500 miles, similar to the Indianapolis 500. However, unlike Indianapolis, the 500 miles would not be run continuously. Instead, three separate 63-lap heats were planned, with an hour break for repairs and rest between each heat, for a total of approximately 500 miles. The overall race winner would be determined by the driver which finished all three heats with the highest average speed. The circuit would be run in an anti-clockwise direction, the same used at Indianapolis, but opposite the direction used by Formula One at Monza.

[edit] 1957

The inaugural running of the Race of Two Worlds was scheduled for Sunday, June 23, shortly after the running of the Indianapolis 500, and a few weeks before the running of the French Grand Prix. USAC's entries in the event travelled from Indianapolis to New York City, from which they were loaded onto a ship and sailed to Genoa. The drivers and personnel travelled separate from their cars, arriving by plane. The teams and equipment was then transported from Genoa to Monza, where teams began practice on Tuesday the 18th.

[edit] Entrants

A total of fifteen cars were entered for the event. Ten cars travelled across the Atlantic from USAC, while only two teams arrived with Formula One equipment. Mario Bornigia used a privateer Ferrari, while Maserati entered their factory driver, Jean Behra. A further three entries arrived from the World Sportscar Championship, thanks to the Ecurie Ecosse Jaguar team, who had just won the 24 Hours of Le Mans the weekend before.

[edit] Practice and qualifying

Although several American teams ran laps on Tuesday, official practice did not begin until Wednesday. All drivers were required to meet speed requirements to qualify: three laps at 185 kph, three laps at 200 kph, and another three laps at 225 kph. All drivers in attendence passed, and began to set their cars for top speed. Eddie Sachs led the first day's practice with a lap time of 56.4 seconds, one of few drivers to lap under a minute. On Thursday, Maserati arrived to enter Jean Behra in the event, but the two cars which Behra practiced with suffered handling problems when they were fitted with larger diameter Firestone tyres, recording a best lap time of 1:03.2 in the team's Formula One car. Maserati chose to not return the following day, joining the already withdrawn Ferrari, and leaving the race without any Formula One machinery.

Qualification was held on Friday, and the USAC teams continued to lower their lap times. Tony Bettenhausen, in the Novi Special, took pole position with a lap time of 53.7 seconds, averaging a speed of 177.046 mph. Eight other USAC cars also qualified, with Paul Russo in the other Novi Special suffering a terminal flywheel failure during its qualification attempt and withdrawing. The three Ecurie Ecosse Jaguars also qualified, but all slower than the USAC entries, due in part to being limited to their Dunlop tyres, which were smaller than the Firestones. The best Ecurie Ecosse time was earned by Jack Fairman, lapping in 59.8 seconds.

[edit] Race

The first heat started on Sunday, with Bettenhausen leading the field toward the starting line where an official waved the Italian flag to begin the race. The trio of Jaguars, although starting at the back, managed to jump to an early lead due to their use of a four-speed gearbox, allowing them to out accelerate the USAC roadsters with two-speed gearboxes. Fairman lead the first of 63 laps before the roadsters were able to build enough speed to catch and eventually pass the Jaguars. Bettenhausen returned to the front of the field, but was forced to reliniquish the lead during the fourth lap with a broken throttle linkage. Pat O'Connor and Jimmy Bryan moved to the front and traded off the lead for half of the heat.

Bryan eventually took command of the lead, pulling away from O'Connor and followers Eddie Sachs and Andy Linden. By the end of the 63 laps, Bryan was leading O'Connor by three seconds, with Linden the only other driver finishing on the lead lap. Bettenhausen, having rejoined the race after repairing the throttle linkage, was the only retirement after a sway bar broke on Lap 45. The USAC entries dominated, earning the first seven positions. Only Bob Vieth's Phillips-Offy was unable to finish ahead of the trio of Jaguars.

Following an hour of repairs, the field began a rolling start for the second heat. In preperation for the Jaguar's ability to accelerate at the start, the lead USAC entries attempted to block the front stretch by running alongside one another. Joe Ruttman took the early lead, followed closely by O'Connor, Sachs, Bryan, and the Jaguar of Fairman. O'Connor soon retired with a broken fuel tank, followed several laps later by Sachs with broke cam house bolts. Ruttman was eventually caught and passed by Bryan, and the two finished in first and second at the end of the 63 laps. Only seven cars were still running at the end of the race, including the three Jaguars running in fifth, sixth, and seventh places.

Another hour for repairs allowed for O'Connor to repair his fuel tank, bringing the entry to eight cars for the final heat. Only seven managed to begin the rolling start, as Ray Crawford remained in his pits to finish repairs. Bryan and Ruttman took the early lead once again as O'Connor was once again forced to retire, his repairs to the fuel tank not holding up to the bumps of the Monza banking. Jack Fairman's Jaguar managed to lead Johnnie Parsons' Kuzma-Offy early, but eventually the three remaining USAC cars lead the three Jaguars to the finish line. Ruttman finished ahead of Bryan, while Fairman once more led the Jaguar trio. With two heat wins, and being the only driver to complete all 189 laps, Jimmy Bryan was declared the winner.

Bryan averaged 160 mph over the 500 miles. For his victory, he won $26,801 in prize money, as well as a unique trophy created for the event.

[edit] 1958

Following a successful running of the first Race of Two Worlds, the Automobile Club of Italy and USAC announced a second running in 1958, to be held on Sunday, June 29th. Several Formula One teams, impressed by the speeds achieved by the USAC teams but also enticed by the large prize sum, promised to attend the event. Ferrari, initially reluctant, entered their own team after the Automobile Club of Italy announced that the Race of Two Worlds was a required event for teams vying for club's cash award for most successful Italian constructor.

Once again, USAC teams were transported from New York City on ships shortly after the Indianapolis 500. Alfa Romeo provided trucks for transport of the teams once they arrived in Genoa.

[edit] Entrants

Once again, ten drivers and cars travelled from the United States to represent USAC. A further two USAC cars were also in attendance, to be driven by Formula One drivers Juan Manuel Fangio and Maurice Trintignant, but set up and run by the American crews. Ferrari, as part of their requirement with the Automobile Club of Italia, brought two unique cars. The first was an older 375 chassis, but using a V12 engine which was used in sports cars. The second was a modified 246, using a Dino V6 engine. Luigi Chinetti's new North American Racing Team also entered a third Ferrari in the event, using another 375 with a smaller V12 engine.

Maserati also built a custom car, their only entry in the event. Based on the design of USAC's cars, the car featured an alcohol-fueled V8 engine which was placed off-center to counteract centripetal force of running on an oval. Learning from their problems the previous year, the car was specifically designed to use the larger Firestone tires. A two-speed gearbox was also used. The Italian Eldorado Ice Cream Company helped fund the effort, and so the car was painted white with their logo written across the side.

Jaguar also had a custom-built car entered, thanks to Lister Cars. A Lister sports car chassis was purchased by the team, modified into a single-seater body style, and fitted with a Jaguar Straight-6 engine from the D-Type. The bodywork was aluminium, and remained unpainted for the event, giving it a near mirror finish. Dunlop tires remained on the front, but the rear was adapted to handle the larger Firestone tires. The team also entered two standard Jaguar D-Types as they had done the previous year, although these were also altered to adapt to Monza's oval. Air scoops were added to the rear fenders in an attempt to help keep the cars' Dunlop tires from overheating.
