The track was inaugurated as a semi-permanent venue in 1953 under the name Autodromo di Imola. The first motorcycle races were held in April 1953, while the first car race followed in June 1954. In its original configuration the circuit had no chicanes, creating long flat-out sections from Acque Minerali to Rivazza and back through the Tamburello corner. This layout remained essentially unchanged until 1972.
In April 1963 the circuit hosted a non-championship Formula One race, won by Jim Clark driving for Lotus. A second non-championship Formula One event was held in 1979, won by Niki Lauda for Brabham-Alfa Romeo. Imola officially entered the Formula One World Championship calendar in 1980, hosting the Italian Grand Prix in a departure from the traditional Monza venue; that race was won by Nelson Piquet. The following year the San Marino Grand Prix was established specifically to allow Imola a permanent slot on the calendar, and the event remained a fixture from 1981 to 2006.
The circuit was renamed the Autodromo Dino Ferrari from 1957 to 1988, following the death of Enzo Ferrari that year, after which the circuit was given its current dual name.
The 1994 San Marino Grand Prix is the event most closely associated with Imola in motorsport history, and one of the darkest weekends in Formula One. During Friday practice, Rubens Barrichello was launched over a kerb at the Variante Bassa and knocked unconscious, though he survived. On Saturday, Austrian driver Roland Ratzenberger lost his front wing at the Villeneuve corner and crashed into a barrier at over 310 km/h, dying instantly from a basilar skull fracture. On race day, three-time World Champion Ayrton Senna crashed into the concrete wall at Tamburello on Lap 7 after his Williams steering column broke; he died in hospital several hours later.
The tragedy accelerated a comprehensive safety overhaul of the circuit. The flat-out Tamburello corner was converted into a chicane, the Villeneuve corner was similarly slowed, and gravel traps were added. These changes permanently altered the character of the lap. Additional modifications were made over subsequent years, including lowering the kerbs at the Variante Alta before the 2006 Grand Prix.
The Tamburello corner had been a focus of safety concern throughout the 1980s and early 1990s. In 1987, Nelson Piquet crashed heavily there during practice after a tyre failure. In 1989, Gerhard Berger's Ferrari ignited after a front wing failure sent his car into the wall at 300 km/h; he survived with hand burns. Michele Alboreto and Riccardo Patrese also suffered significant shunts at Tamburello in testing during the early 1990s.
Formula One left Imola after the 2006 San Marino Grand Prix. The circuit owners subsequently undertook major reconstruction work to the track and pit lane facilities, overseen by German F1 track architect Hermann Tilke. The FIA awarded the circuit a Grade 1T rating in June 2008 and full Grade 1 homologation in August 2011.
Imola returned to the Formula One World Championship calendar in 2020 as host of the Emilia Romagna Grand Prix, replacing a race cancelled due to the COVID-19 pandemic. The event was retained for 2021 and 2022, dropped for 2023 after the circuit was flooded by the Santerno river, then reinstated for 2024 and 2025.
Imola has hosted a wide variety of international championship rounds beyond Formula One. The Superbike World Championship has visited the circuit from 2001 to 2006 and again from 2009. The circuit hosts the final round of the FIM Motocross World Championship since 2018. The World Touring Car Championship used Imola for events in 2005, 2008, and 2009. Endurance racing has also been prominent, with the 6 Hours of Imola and later the 4 Hours of Imola as part of the European Le Mans Series calendar.
The official lap record for the current Grand Prix layout stands at 1:15.484, set by Lewis Hamilton during the 2020 Emilia Romagna Grand Prix.
Imola occupies a unique place in motorsport culture, particularly in Italy, where it is considered one of the home circuits of Scuderia Ferrari given the team's base in nearby Maranello. The circuit's role in the events of 1994 made it a site of pilgrimage for motorsport fans, and the Tamburello corner retains deep symbolic significance. The circuit has demonstrated continued relevance by attracting Formula One after a thirteen-year absence, and its combination of high-speed sections and technical corners keeps it a favourite among drivers and fans alike.
