The 1912 Grand Prix season saw Grand Prix motor racing in Europe and the United States. The growing economic confidence and interest from car manufacturers saw bigger fields and more races in the season. The French Grand Prix was held for the first time since 1908 and staged at Dieppe. The American Grand Prize was held in Milwaukee, moving from its previous home in Savannah. Peugeot was the team to beat this year, with their new twin-cam 7.6-litre L-76. In the French Grand Prix, after American David Bruce-Brown’s FIAT had retired after leading for most of the two-day race, victory went to the Peugeot of Georges Boillot. Team-mate Jules Goux repeated the success at the Coupe de la Sarthe held at Le Mans. The Peugeot voiturettes had also won at Le Mans and Ostende. However, it was a British Sunbeam that was first voiturette home at Dieppe. In the three big races in the United States Joe Dawson won the second running of the Indianapolis 500. Ralph DePalma beat a small field in the Vanderbilt Cup. In the American Grand Prize held over the same weekend, rising star David Bruce-Brown was killed in practice while Caleb Bragg won the race in a FIAT S74. This year no European drivers travelled across the Atlantic for the events. With four victories over the season, Ralph DePalma driving a Mercedes, was acclaimed as the AAA national champion for the year. Major Races Sources: Technical Basic attempts at aerodynamics appeared this season, as cars started to shape their tail sections to cover the fueltanks and spare tyres. At Peugeot, the three driver-engineers Georges Boillot, Jules Goux and Paolo Zuccarelli (dubbed “The Charlatans”) had worked with Ernest Henry and produced their first design. Fellow Peugeot-engineer Ettore Bugatti had also produced a design and the two had a run-off. The drivers’ car was comfortably faster, reaching , built with a four-cylinder 7.6L engine. The innovative twin-overhead camshaft, with four valves per cylinder, developed 148 bhp revving at 2200rpm. This was equivalent to nearly 20 bhp per litre and 50% higher than the performance of its main rival, the Fiat S74, that only gave 13 bhp per litre at a leisurely 1600rpm over its 14.1 litre engine. Although some of the ideas were not new, it was Peugeot that combined them and pioneered the use of hemispherical combustion chambers. There is some evidence that Zuccarelli got the
