The Imola circuit has had to pay a fine after Red Bull conducted a filming day at the circuit last year that set off noise pollution detectors.
Red Bull took to the track last October with the 2013 RB9, which was the last of the naturally aspirated cars used in F1.
The 2014 successors became considerably quieter amid the introduction of turbo-hybrid Power Units.
The RB9, the car that took Sebastian Vettel to his fourth and final world title, was detected by noise pollution sensors in the area, and has resulted in a fine of €500.
Elena Penazzi, Councillor for the Autodrome, Tourism and Citizen Services of Imola said, as quoted by Corriere dello Sport: “The Red Bull event was the only occasion on which the Autodrome has made noise in the past year, always remaining within the limit, despite the many activities carried out.
“On 12 October, Red Bull showed up with an older car than the current one and the limits were exceeded. It was a matter of a few laps.”
Imola returned to the F1 calendar in 2020 after being absent from the calendar for over a decade.
It is currently contracted to host an F1 race until 2025.
F1 teams are permitted to run two filming days throughout the year with their current car, which are restricted to 100km each on non-race specification Pirelli tyres.
Rules are looser with older generation cars, with teams often using them in demo runs as well as recording purposes for marketing commitments.
