1950 Carrera Panamericana

After the Mexican section of the Pan-American Highway was completed in 1950, a nine-stage, six-day race across the country was organized by the Mexican government to advertise this feat and to attract international business into Mexico. The race ran almost entirely along the new highway, which crossed the country from north to south for a total distance of over 3,300 kilometres (2,100 mi). Antonio Cornejo, a Pontiac dealer in Mexico City, was the general manager of the event.

Racers from the US, Italy, France, Spain, Venezuela, Colombia, Guatemala, Peru and obviously, Mexico. The Formula 1 drivers Piero Taruffi and Felice Bonetto took part in the race. Also Bill France Sr., the founder of NASCAR. Other NASCAR drivers participated as Hershel McGriff, Curtis Turner. The sports car racer Jean Trévoux also took part.

The first race ran from north to south, beginning in Ciudad Juárez, Chihuahua, across the international border from El Paso, Texas, and finishing in El Ocotal, Chiapas, (now known as Cd. Cuauhtémoc) on the Guatemala–Mexico border opposite from La Mesilla, Guatemala. At least one stage was run each day for six consecutive days. The elevation changes were significant: from 328 ft (100 m) to 10,482 ft (3,195 m) above sea level, requiring amongst other modifications re-jetting of carburettors to cope with thinner air. Most of the race was run between 5,000 ft (1,500 m) and 8,000 ft (2,400 m).

The first three places were won by American cars and American drivers. The winner, Hershel McGriff, drove an Oldsmobile 88 at an average speed of 142 km/h (88 mph). Though less powerful, the car was substantially lighter than its big Lincoln and Cadillac competitors, meaning that it would eventually pull away from them on the steep, winding course. The car (which had cost McGriff only $1,900, when the winner's purse was $17,000^[1]), had another advantage in its weight – it was much easier to stop, meaning that McGriff finished the race on his original brake shoes when the big cars were re-shoeing every night. The reason that this was so important was that neither McGriff nor his co-driver were capable of even the most basic maintenance to the car.^[1] McGriff also noted that the control afforded by his manual gearbox gave him a significant advantage the last day on the gravel roads in Chiapas, when he finally passed the Cadillac leading the race. The best placed European car, in fourth position, was an Alfa Romeo 6C driven by Italian driver Piero Taruffi.
