Holden's commitment to the Supercars championship will formally end at the completion of the 2020 season

The manufacturer has revised its agreement with Triple Eight Race Engineering to provide factory support for the Red Bull Holden Racing Team after news earlier this year that the brand would be retired by parent company General Motors.

While Holden's contract with Triple Eight originally ran until the end of the 2021 campaign, an agreement has been reached to terminate the contract a year early.

It will mean the powerful Red Bull team, which features multiple championship winners Jamie Whincup and Shane van Gisbergen, could line up in a different brand of car from 2021 onwards.
