1958, the first year of production, they produced 1,025 units which then expanded to over 4,000 in 1959, the first full year of the new Grugliasco factory. The second generation of leadership Starting with the planning for the new plant in Grugliasco in 1956, Farina started to groom his replacements–Sergio his son, and Renzo Carli his son-in-law. To his heirs apparent, Farina said of the Corso Trapani facility, "This old plant has reached the limits of its growth. It has no room for expansion and is far from being up to date. If I were alone, I'd leave it as it is. But I want you to decide which way to go–to stay as we are or to enlarge. Either way is fine with me. It's your decision to make and I don't want to know what it is. I'm finished, and it's your time to take over. The future is absolutely up to you." In 1958, upon leaving for a world tour, Farina added, "In my family, we inherit our legacies from live people–not from the dead." Change of corporate name to Pininfarina In 1961 at the age of 68, "Pinin" Farina formally turned his firm over to his son Sergio and his son-in-law, Renzo Carli, it was the same year that the President of Italy formally authorized the change of Farina's last name to Pininfarina, and the business took on the same name. Pininfarina was run by Battista's grandson Andrea Pininfarina from 2001 until he died in 2008. Andrea's younger brother Paolo Pininfarina was appointed successor. Modernizing for a new world Starting in the mid-1960s, Pininfarina started to make investments in the science of automotive design, a strategy to differentiate itself from the other Italian coachbuilders. In 1966, Pininfarina opened the Studies and Research Centre (Studi e Ricerche) in Grugliasco. The research centre occupied 8,000 sq. metres (2 acres) and employed 180 technicians capable of producing 25 prototypes a year. The Calculation and Design Centre was set up in 1967, the first step in the process of technological evolution that, during the 1970s, would take Pininfarina into the lead in automated bodywork design. Then in 1972 construction of a full-sized wind tunnel was completed. The project was started in 1966. When it opened, it was the first wind tunnel with the ability to test full-sized cars in Italy and one of the first in the world with this
