The series was put on hiatus in March of 2015 after Jeremy Clarkson was suspended by the BBC following a fracas with a producer on the show, Oisin Tymon; at the time, seven episodes of the series had aired. An investigation was conducted by the BBC after which Clarkson was dismissed from the show on the 25th of March, 2015. Subsequently, Clarkson's co-presenters Hammond and May announced that they would leave the show shortly after and the show's executive producer, Andy Wilman, also announced his resignation. As such, the series marks the final appearance of the show's iconic presenting line-up of Jeremy Clarkson, Richard Hammond and James May.
No doubt spurred on by the myriad of controversies which occurred before, during, and after the series aired, viewing figures stabilised in comparison to its immediate predecessor, retaining the 6.49 million average that Series 21 set. Only one episode would fail to break the 6 million view mark, and the 7 million view mark would almost be broken three times, the final episode falling short by just 80,000 viewers. With the controversies surrounding the show and its main host, Jeremy Clarkson, coming to a head through the assault of Oisin Tymon in March 2015, the show would be renewed, with Hammond and May offered to retain their roles as hosts, though Jeremy Clarkson would be dismissed. This would put the show on hiatus for over a year, as all three hosts left to produce rival show and spiritual successor The Grand Tour.

After many months of speculation, on the 9th of June, 2015 the BBC finally confirmed that a final special episode was in production which would compile some of the unaired footage from the series. The episode was the first in modern Top Gear history in which Jeremy Clarkson was not featured as a presenter for the studio links, his role taken up by an elephant of the same name. These segments featured only James May and Richard Hammond, and did not have an audience.
The episode combined the two main features from the cancelled eighth and ninth episodes which saw Clarkson, Hammond, and May partake in a classic car challenge and attempt to purchase the best second-hand SUV for less than £250.
A pair of teasers for the episode were revealed on the 9th of June, 2015. Later, the BBC announced that the 75-minute-long episode would air on the 28th of June, 2015.
Although the episode made use of the majority of the footage that was shot for the remainder of the series, there remains a number of films that were shelved and will likely never be seen. The main film that was to be featured in the tenth episode was being filmed at the time of Jeremy Clarkson's dismissal and was likely incomplete. Furthermore, Richard Hammond was due to review the new Subaru WRX in Episode 8 and Clarkson was set to conduct a power test of three limousines in Episode 9. It is unknown if either of these films were shot.
- Filming of the series was conducted in countries spanning a total of five continents, including North America, South America, Europe, Africa, and Australia/Oceania. The only continent left unvisited was Asia.
- The series marks the final appearances of Clarkson, Hammond and May as presenters on the show. May would remain, whilst under contract from Amazon, to produce the final three episodes of Cars of the People.
