Matt Braid has resigned from his managing director role at Supercars and will leave the sport at the end of the season.

The former Volvo Car Australia boss joined Supercars as commercial director in 2015 after an 11-year stint at the Swedish car firm.

He was elevated to the managing director last year and was subsequently charged with delivering the SuperUtes category, which has been postponed 12 months until next year.

Braid, who also played a key role in the launch of the Super5000 series, is understood to have cited personal reasons for his decision to leave the organisation.

CEO James Warburton said Braid had advised him of his resignation this morning, following a change in his personal circumstances which prevented the extensive travel the position requires.

“Matt has done a tremendous job in rebuilding our commercial sales operation into a very robust and successful team which is a market leader in Australian sport,” Warburton said in a statement issued to Speedcafe.com.

“The sport has never been stronger commercially and the proof is not only in our results but in the calibre of new partners we have secured in recent times.

“Personally, Matt has been an enormous asset in running the day to day operations of the business which collectively has allowed us to achieve some outstanding results and momentum.

“Matt has also worked tirelessly on a number of 2025 vision projects, most notably the recent SuperUtes Series and announcements which will come to life in 2018, as well as the Super5000 concept.

“I look forward to working with Matt for the remainder of the year and taking more steps towards realising our 2025 vision. We will be sorry to see him go, but family always comes first.”

It is yet to be determined who will replace Braid in the position.
