Rodríguez was born in Mexico City and was a child cycling champion who switched to motorcycles in domestic competition from the age of 11. He was the third son from the marriage of Pedro Natalio Rodríguez and Concepción "Conchita", he had four brothers and sisters, Pedro, Federico, Conchita and Alejandro. He was married to Sara in July 1961 but left no children. In the summer of 1962 his close friend, Jo Ramírez, would accompany Ricardo to his adventure in Europe.
Career
He won several national motorcycle titles, before taking up saloon car racing in his own Fiat Topolino. In 1957 he made his international debut at Riverside, beating all comers in the under 1.5 litre class in a Porsche RS. He then won his class in a Porsche Spyder in the NassauTourist Trophy. He often raced for the North American Racing Team with his brother Pedro, although he would also enter cars under his own team's name, Scuderia Rodríguez. He was refused an entry at Le Mans in 1958 because he was too young, but went back in 1959 to race an OSCA in the 750cc class. In the edition of 24 Hours of Le Mans in 1960 he partnered André Pilette to second place. At 18 years and 133 days of age, he is the youngest driver ever to stand on the podium at Le Mans. Rodríguez was given a guest drive by Ferrari for the 1961 Italian Grand Prix, qualifying a surprise second and becoming the youngest driver in history to start from front row, a record that wouldn't be beaten until the 2016 Belgian Grand Prix by Max Verstappen. In the race he exchanged the lead with Phil Hill and Richie Ginther many times, until a fuel pump failure ended his race. 1962 saw a full works drive with Ferrari, who used him sparingly considering his age and rough edges. Whenever used, Rodríguez shone, taking second at the Pau Grand Prix, fourth at the Belgian Grand Prix and sixth at the German Grand Prix in a tough year in Formula One for Ferrari. He also won the 1962 Targa Florio edition with Olivier Gendebien and Willy Mairesse in a Ferrari 246 SP. Rodríguez was considered a potential future champion already, but was left without a drive when Ferrari opted not to enter the non-Championship 1962 Mexican Grand Prix at the Magdalena Mixiuhca Circuit, Mexico City. He signed to drive Rob Walker'sLotus 24, but died during the first day of unofficial practice, when the Lotus' rear right suspension failed at the fearsome Peraltada turn, and it hit the barriers, killing him instantaneously. He was 20 years old and his death provoked national mourning in Mexico. The Scuderia Rodríguez A.C. keeps his memory and that of his brother alive. It serves as register for Rodríguez memorabilia and cars, certifying them, and its Secretary General Carlos Jalife published their biography in 2006, and a second edition came in 2015. He did an English translation that was published in 2009 and won the Motor Press Guild Book of the Year.
