Series 22 of Top Gear, a British motoring magazine and factual television programme, was broadcast in the United Kingdom on BBC Two during 2015, consisting of eight episodes - seven of these were aired between 25 January and 8 March, while the eighth was aired on 28 June following a disruption in production; two additional episodes were planned but never produced. The series was preceded by a two-part special focused on the presenters conducting a road trip across Argentina, titled Top Gear: Patagonia Special, and aired during 2014 on 27–28 December. This series' highlights included the presenters conducting a race across St. Petersburg, creating home-made ambulances, a recreation of a famous Land Rover Defender advert, and a road trip across Australia in GT cars. This series was the final to feature Jeremy Clarkson, Richard Hammond and James May as the programme's presenters, and Andy Wilman as its executive producer, after an incident during production of the twenty-second series, involving accusations of physical and verbal abuse, led to the BBC dismissing Clarkson from the programme, which subsequently led to the others to resign in April 2015. The BBC's investigation into the accusations brought an abrupt hiatus to the programme after the seventh episode, with Hammond, May and Wilman agreeing to produce one final episode featuring two films that had been completed before production was disrupted. The two-part special that had preceded this series also drew international attention when the presenters faced problems completing filming and facing threats to their lives by residents of the Patagonia region over claims a car they drove had number plates deliberately referencing the Falklands War. To mark the end of the trio's era of presenting Top Gear, the BBC produced a two-part compilation special, titled Top Gear: From A-Z, which aired on 26–30 December 2015, and was narrated by comedian John Bishop. The special featured the best moments of the past twenty-two series of the programme, and included comments by a number of celebrities and sporting personalities about the presenters' work. Production News that production of the series was being planned was hinted by Clarkson on Twitter on 29 April 2014, before he later confirmed on 7 July that year that he was going to Morocco to start filming for the show, with a media outlet in Australia further revealing on 24 October and 29 October that the trio were filming within the country's Northern Territory.
