In the final episode of the current series aired on Sunday, viewers watched as presenter James May drove a Ferrari California Spider worth £5.6m, owned by BBC Radio Breakfast show host Chris Evans.
At one stage, May drove through Windsor and had to reverse the sports car on a tight road after being blocked in by three cars supposedly driven by learner drivers.
"Oh God not here, don't say you want to go backwards," he said, before wincing when the cars narrowly missed the Ferrari's paintwork as they manoeuvred past.
However, a newspaper report revealed that the drivers were not in fact learners, but actually their driving instructors, led by fully qualified Rob White.
Speaking to the Evening Standard, an instructor for the Clearway Driving School said that the sequence had been filmed in November 2009.
She added: "We were told not to bring learner drivers because of the value of the car, so it was the instructors who were really doing the driving. Their remit was to get in his way and make life awkward for him. We were there for comic effect."
In a statement, a BBC spokesperson said that the set-up was "a light-hearted take on the perils of driving one of the rarest and most valuable cars on the road".
They said that Top Gear is "not a documentary", but added that the scene in which school children ran towards the Ferrari was real.
Ofcom said that it had not received any complaints about Sunday's episode.
Top Gear is one of the BBC's most popular programme brands, but the show has regularly been accused of 'faking' scenes for the purposes of entertainment.
In 2009, bosses on the show admitted to setting up a stunt in which James May piloted a caravan adapted into an airship over Norwich airport, attracting the supposed ire of authorities.
At the time, a BBC spokesperson said: "As an entertainment programme, Top Gear prides itself on making silly films that don't pretend to represent real life. Any suggestion it deliberately misled viewers is patently ludicrous."
