Triple Eight Race Engineering will field an all-new race engineering line-up next season.
It was confirmed Wednesday that David Cauchi will leave the team for Kelly Grove Racing in 2022.
Cauchi, who shifted to Shane van Gisbergen's #97 Red Bull Ampol Racing entry this season, will replace Todd Kelly as the Braeside squad's Team Principal.
Wes McDougall, who has been engineering Jamie Whincup's #88 entry in 2021, will also depart the team at season's end.
Veteran McDougall joined the team this year from Matt Stone Racing.
It comes after Grant McPherson left Triple Eight at the end of 2020 to join Walkinshaw Andretti United.
McPherson was previously van Gisbergen's race engineer between 2016 and 2020.
He notably helped van Gisbergen to a championship in 2016, and Bathurst victory last year.
Cauchi is a long-term member of the Triple Eight family, having joined the team in 2007 as a data engineer.
He took over from Mark Dutton on Whincup's car in 2014 and helped the driver to the 2014 and 2017 championships.
Cauchi and van Gisbergen have been a force in 2021
Dutton, himself a decorated race engineer, is now Triple Eight's Team Manager.
The team will also feature a new-look driver line-up in 2022, with van Gisbergen to be joined by Broc Feeney.
Current Super2 points leader Feeney will replace Whincup, who himself will replace Roland Dane as Managing Director and Team Principal.
With McPherson and Cauchi both on the way out, van Gisbergen will have his third race engineer in as many years in 2022.
The 2021 Repco Supercars Championship will continue at next weekend’s Bunnings Trade Sydney SuperNight. Tickets for all four upcoming Sydney events are on sale now.
All sessions will be broadcast live on Fox Sports and streamed via Kayo. The Seven Network will broadcast live from 3:30pm AEDT on Saturday and 12:30pm AEDT on Sunday.
