Giannini Automobili S.p.A. is an Italian tuning company that was founded by Attilio and Domenico Giannini in 1920. Initially, the company was focused on repairing and tuning up cars, but later on, it began producing its own cars based on Fiat models. Giannini became known for its racing successes, especially in the 1960s and 1970s, when it won several Italian rally championships with its modified Fiat cars. The company's headquarters are located in Rome, Italy, and it continues to specialize in performance upgrades and modifications for Fiat cars, including exhaust systems, suspension upgrades, and engine tuning. However, it no longer produces its own cars.
