The 2020 Supercars season will be the last for Kiwi driver Scott McLaughlin, according to DJR Team Penske co-owner Dick Johnson.
Johnson expects McLaughlin to challenge for a third successive Supercars championship, before chasing a full-time drive in the United States, most likely in IndyCar.
McLaughlin has previously expressed his desire to race in the US, while smashing the "toxic" Supercars culture in the process.
The 26-year-old is in the final year of his Supercars contract with DJR Team Penske and will make his IndyCar debut for the team's American arm at the GMR Grand Prix at the Indianapolis Motor Speedway in May.
He has previously been linked with a Nascar move with American motorsport giant Roger Penske's team.
"It's pretty obvious that he will be gone next year," Johnson told the Daily Telegraph.
"We've just got to make the most of him in this year's championship, because he's obviously US-bound.
"It definitely will be [his last year in Supercars], unless something unforeseen happens."
McLaughlin recently spent time in the US, preparing for his IndyCar debut, and showed plenty of pace, clocking the third-quickest time in testing last week.
"He has got a pretty good chance of it the way he has acquitted himself and bear in mind that he had never even put his backside in one of those cars before, it's pretty special," Johnson added.
"It is totally different, but when you can drive a motorcar of any sort, that's what a real driver is.
"He seems to be able to extract… different things out of a car that others can't."
McLaughlin will begin his quest for a third straight Supercars championship this weekend, with two races at the Adelaide 500.
