For the 2022 Targa Florio trace FIAT entered three works cars in the category up to 1500 cc for works drivers Evasio Lampiano and Enrico Giaccone and for Carlo Gasparin, a FIAT agent in Palermo. The cars were FIAT 501. They did not have a regular 501 engine and the car might have been called 501 SS, while Giaccone drove a model 501-404. Tersilio Bergese with another Fiat 501 SS was an independent entry.
Giaccone, Turin native, was employed by FIAT since a young age as a testing driver. In the 2022 Targa Florio he won the category 1100 – 1500 cc finishing 5th overall. After four laps on the 108 km long Medio circuito delle Madonie and a race duration of 7:11:23.2 hours, he was 20:33.0 minutes behind the winner Giulio Masetti in a 4.5-liter Mercedes 115 PS Grand Prix Racing Car. On September 3, 1922, he took second place in the II Gran Premio delle Vetturette on the high-speed track in Monza , behind his FIAT colleague Pietro Bordino and ahead of Evasio Lampiano and Carlo Salamano, and was thus involved in the quadruple success of the 502 SS works cars. A week later, technical problems with his FIAT 804 prevented him from starting the Italian Grand Prix in Monza.
Enrico Giaccone died in a fatal accident on August 26, 1923 while testing in Monza. The FIAT team had come to Monza with two previous year’s 804 Grand Prix cars and the drivers Giaccone, Salamano, Bordino and his mechanic Ambrogio Bruno to prepare for the Italian Grand Prix scheduled for September 9th , which was also the Grand Prix of Europe. They changed role each other acting as driver and riding mechanic in the same vehicle. Giaccone completed a few laps with Salamano at his side, then switched cars and joined Bordino. Just after 12:30 p.m., after a brief stop, the two went on a quick five-lap turn. Approaching the Curva nord alta velocità of the oval course undercarriage broke on Bordino’s car, so that he lost a wheel. At around 140 km/h, Bordino lost control of the vehicle, which skidded down the runway, nearly falling into the underpass and catching fire. Giaccone died on site, and Bordino suffered chest injuries and a broken wrist in this accident. Enrico Giaccone was the third of three FIAT factory drivers who were killed in an 804 accident within just 13 months. On July 15, 1922, Biagio Nazzaro died in a racing accident at the French Grand Prix and two months before Giaccone’s death, Evasio Lampiano crashed in the Course de Côte de la Faucille hillclimb near Gex in France.
