Part 2 describes the development of the Garros Type Bugatti and the car when owned by French hero Roland Garros.
The Development of the Bugatti “Roland Garros”
Before he set up his own company, Ettore Bugatti designed engines and chassis for various manufacturers, among them De Dietrich, Hermes, Mathis, Deutz and Peugeot. Bugatti’s own factory in Molsheim was operational in 1910 but he continued to work for others. One of these projects for Peugeot was to design racing car for the 1912 Grand Prix de l’Automobile Club de France and the Coupe de l’Auto.
The engine Bugatti developed for Peugeot was a large (around 5 liters) four-cylinder with a single overhead camshaft. One can quite well understand that Ettore drew on his experience with an earlier design he had done for Deutz, and also incorporated design features of the small engine he produced under his own label. Apart from the size of bore and stroke, the main difference was that the larger engine had three valves per cylinder (two inlet valves and one exhaust valve).
1910 Bugatti-designed Deutz had a SOHC, Bugatti's first. Note chain drive.
