Seven-time Supercars champion Jamie Whincup will drive on next year, ending speculation about his future.

The Holden great had been weighing up whether to continue and will use the season-opening Adelaide 500 to announce his plans on Saturday.

The 37-year-old has been open about considering all options during the off-season.

But another campaign with Red Bull will extend his glittering career into an extraordinary 20th Supercars season.

Discussions about Whincup’s future only intensified in October when he was elected to the Supercars Commission, a year after taking a 15 per cent stake in Triple Eight.

Whincup will again form an all-star duo with 2016 champion Shane van Gisbergen.
