INDIANAPOLIS — A social media post designed to introduce drivers in the Indianapolis 500 to the general public put Josef Newgarden in an awkward light when the reigning race winner was asked a simple question.

“Which IndyCar driver would you take on a road trip?” asked the questionnaire.

“Solo” Newgarden responded.

An odd answer for a driver who a year ago was practically inseparable from Scott McLaughlin, his Team Penske teammate. The “Bus Bros.” had a media company, a YouTube show and merchandise. They appeared to be the best of friends and McLaughlin celebrated Newgarden when the Tennessean finally broke through to win his first Indianapolis 500.

Twelve months later, the Bus Bros. are no more, the friendship apparently unraveled after Newgarden went solo and unfollowed everyone on social media — including his wife — in a bid to rebuild his love of racing. Winning the Indy 500 wasn’t as fulfilling as he had expected; for the two-time IndyCar Series champion, racing had become a grind of too many failures and not enough successes.

Insulated but re-energized when he returned for this season, Newgarden scored an emphatic victory in the opening race in St. Petersburg, Florida. Six weeks later, IndyCar discovered illegal push-to-pass software on the three Team Penske cars and threw out both Newgarden’s win and McLaughlin’s third-place finish.

Newgarden returns to the speedway for Sunday’s race as the defending Indy 500 winner but caught in a cheating scandal that has damaged his pristine reputation and that of Team Penske. A deeply embarrassed Roger Penske suspended four team members, including team President Tim Cindric, Newgarden’s strategist.

If the drama is distracting Newgarden, he’s not let on.

He qualified third to complete Team Penske’s first front row lockout in Indy 500 qualifying since 1988. McLaughlin won the pole and Will Power qualified second.

Asked how different this year has felt from last season, when Newgarden won in his 12th try, he felt nothing much has changed.

“Feels really similar to me in a lot of ways. I feel a lot of respect for this facility and this race, this track,” Newgarden said before turning the topic to how good his Chevrolet was a year ago. “We were fortunate enough as a team, as a group, where it just fell into place for us. We had a great car. ... It was our day.

“I feel the same in that regard. I think I’ve got another great race car,” he continued. “I had sort of let go of the fact that I was ever going to win this race. It’s such a tough race to win, I think you had to be comfortable with that. I think that rings true for a second. I’m happy to be here, happy to have a shot.”
