Grove Racing is set to field the youngest Supercars team on the grid after signing Super2 champion Kai Allen for the 2025 season.
Tuesday's announcement comes after the team opted against renewing Bathurst winner Richie Stanaway's contract in July.
Allen will join Grove on an undisclosed long-term deal and will drive car No.26, alongside Matt Payne.
Currently driving in the second-tier Super2 championship for Eggleston Motorsport, the 19-year-old is striving to clinch back-to-back titles after winning the division last year.
Allen will also team up with Dick Johnson Racing later this year for the Sandown 500 and Bathurst 1000.
"It's pretty surreal! I've been racing since I was eight years old, maybe even younger, so I'm super grateful to finally be in a position that I've worked towards my whole life," Allen said in a statement.
"It still hasn't sunk in, but I'm sure come round one next year that will all change."
Returning to Supercars this season after walking away in 2019, Stanaway's future in the sport remains uncertain.
The 32-year-old sits 13th in the standings ahead of the Tasmania SuperSprint set to get underway on August 16.
Meanwhile, reigning champion Brodie Kostecki is expected to leave Erebus Motorsport following an off-season dispute, with his contract set to expire at the end of the year.
