The company said Tuesday Pininfarina died overnight at his home in Turin. No cause of death was given.
The company founded in 1930 has designed cars for Fiat, Alfa Romeo, Cadillac and Volvo but is most closely associated with Ferrari, designing nearly all of its models since the 1950s.
It ceased making car bodies in 2010 to focus on its design and engineering businesses.
Pininfarina took over as president in 1966, upon the death of his father. He stepped down to become honorary president in 2006 and was also named a senator for life.
He is survived by his wife and two children.
