Following
Jeremy Clarkson's dismissal from the show on 25 March 2015, after the
BBC decided not to renew his contract, On 16 June later that year, Evans was confirmed as one of the new hosts for the show,
Carl Fogarty,
Chris Harris and
Sabine Schmitz were all reported to be in the running to present the show alongside Evans; Fogarty subsequently ruled himself out of the running. News of who else was to join remained a mystery, with Evans even commenting that he could be left hosting the show himself, but on 4 February 2016, American actor
Matt LeBlanc was officially announced as part of the hosting line-up to work with Evans. A week later on 11 February, during his
BBC Radio 2 Breakfast Show, Evans confirmed that he and LeBlanc would be joined by
The Stig, along with four other new presenters who had each won an open audition to be part of the show –
Eddie Jordan (who split with doing F1 Coverage following the BBC's decision over the sport's coverage), Harris, Schmitz, and motoring journalist and Sky television presenter
Rory Reid. Of the relationship between the six new presenters, Evans stated in an interview with
BBC News that it was decided that only he and LeBlanc would front the show weekly in the studio segments, whilst the other presenters would "come and go as and when required". Production on the series, alongside filming, included dropping the
Cool Wall and
News segments, while overhauling the celebrity segment after the abrupt end of
Series 22 had led to the subsequent decision sending the
Vauxhall Astra Tech Line back to its manufacturer, where it was later auctioned off on 27 December 2015 for £17,800. Renamed as
Stars in a Rallycross Car, the segment featured a longer interview process, with two celebrities invited to the show for each episode (as had happened before in
Series 11), before taking to a new circuit in a modified
Mini Cooper that had been prepared for rallycross driving. The new rallycross circuit provided for the remade segment, incorporated parts of the existing Top Gear Test Track, such as the use of "Gambon", but included two new off-road sections, which featured a water splash obstacle and a jump; the existing circuit received a cosmetic update to the line markings – still used for "Power Laps". A revamp of the studio at
Dunsfold was also conducted to match the new look of the show, with work including providing more space for the audience, relocation of the stage area, and less use of monitors and light scaffolding around the rest of the studio. In addition, the revamp also saw the removal of the plinths used by the former hosts' cars (including the one for
Toyota Hilux) as well as the cars used on them, but retaining the banner for
The Stig. In addition to work being done to create the new series, the BBC announced on 27 April 2016, that production of a spin-off show called
Extra Gear for
BBC Three, was also being worked on, which was to feature additional clips and behind-the-scenes look at some of the films shown on each episode that was broadcast of Series 23, with both Rory Reid and Chris Harris announced as the presenters for it. ==Episodes==
