Fiat's 512 was first produced in 1926. It was a four-door passenger car available as a limousine, sedan, or convertible. The car was the successor to the 510 and was produced with an inline 6-cylinder engine and weighed almost 4,000 pounds. Only 2,600 units were built before it ceased production in 1928. Fiat followed the 512 with the 503.
