.Story: In 1913, Jules Goux won the Indianapolis 500 Grand Prix in a Peugeot with the in-line four-cylinder engine designed by Ernest Henry. This design featured the first use of two overhead cams and four valves per cycle, making it highly influential as a racing engine. To this day, it is also the structural standard for in-line four-cylinder engines used in racing cars.
.Birth of the In-line 4-cylinder engine: In 1894, Maybach and Paul Daimler completed the development and design of the in-line four-cylinder engine with the cast cylinder block, using the carburetor patented technology that Maybach had just obtained in 1893.

This was done shortly after Maybach and Paul Daimler were pushed out of the company.
