A week after the end of the Cup season, the seven-time Cup champion swapped rides with Formula One star Fernando Alonso and piloted a F1 car around the Bahrain International Circuit.
It was the third such swap between NASCAR and F1 drivers following the Jeff Gordon-Juan Pablo Montoya switch in 2003 at Indianapolis and the Tony Stewart-Lewis Hamilton swap in 2011 at Watkins Glen.
On Tuesday, Johnson expressed a desire to see “more crossover” between auto racing’s elite in competitive circumstances and to see stars moonlighting to support smaller series.
“I just think that in motorsports in general, we need guys to cross over from a local level,” Johnson said during Hendrick Motorsports’ media day after being asked about NASCAR’s influence in the Chili Bowl Nationals. “Although the Chili Bowl is huge, but they’re Midgets and more people typically get their starts (at that level).
“Our stars come back down and run and put on such a great show. That helps them and I think it helps us. It also helps that community and there are a lot of young drivers that are trying to find their way up.”
The Chili Bowl, held last week in Tulsa, Oklahoma, was won by Xfinity Series driver Christopher Bell for the third straight year. He had to battle Cup driver Kyle Larson in the final feature, with the outcome being decided with a last-lap pass.
Johnson then turned to the major racing series and the lack of crossover between them in recent years.
“Hopefully we can get more crossover going, even between IndyCar and NASCAR or NASCAR and Formula 1 or whatever it might be,” Johnson said. “I feel like we had a lot of heroes that we looked up to and those guys would race anything and everything.
“And in the last 20 or 30 years, we’ve focused more on championships than we have marquee events. And I completely understand why, but it’s really nice to see people trying to move around and race other things. Hopefully we’ll have somebody trying the double again at Indy and Charlotte. There is a lot of good that comes from those opportunities.”
Kurt Busch was the last driver to attempt “The Double” of competing in the Indianapolis 500 and Coca-Cola 600 on the same day in 2014.
The prospect of Larson, who competes for Chip Ganassi Racing, making the attempt has been brought up on a somewhat regular basis in recent years with Larson saying in July 2017 that violent IndyCar wrecks at IMS have kept him from committing to it.
In 2016, Brad Keselowski teased everyone when he took a few laps around Road America in a Team Penske IndyCar during a test.
There were crossovers between IndyCar and NASCAR in 2018 with Danica Patrick competing in the Daytona 500 and Indy 500 and a Xfinity Series start by Conor Daly at Road America.
That goes both ways. In November, Johnson expressed a desire in giving IndyCar a try on road courses.
But Johnson said he doesn’t have any forays into other series planned right now.
“I have some great new friends at McLaren and they have lots of things getting involved with racing-wise,” Johnson said. “So, down the road there could be some opportunities there for me potentially. I’d love to go endurance racing with Fernando (Alonso).
“We joked about that some. Nothing has developed from that yet, but hopefully down the road we can send some more teasers out and have some more fun.”
