The battle for the title has raged the entire season with five changes at the top so far and it will come as no surprise if there is another lead change come Monday morning.
Not only have the drivers been struggling for consistency, teams at both ends of the spectrum have struggled this year.
One of the best, longest-serving and most successful IndyCar teams, Target Chip Ganassi Racing, notched up only their first win when Dixon took his first chequered flag of the season.
At the other end of pit lane is Sarah Fisher Hartman Racing, who came so close to winning their very first race.
Their young driver, Josef Newgarden, has showed great promise finishing second at Iowa and has led a few races until being beset by numerous dramas. In fact, he was on for his first win at Mid-Ohio until he ran over an air hose resulting in a drive-through penalty.
For Sarah Fisher, the first and only female owner of an IndyCar team, it was a heartbreaking moment. Motor racing is a fickle mistress, but to have a probable first win snatched away from you really hurts.
"That was hard, we definitely gave that one away as a team. It was such a shame," Fisher said after the race.
"We've been in that position a number of times this season and haven't managed to complete the deal.
"Josef is a great kid and he works really hard at what he does."
Fisher had a pretty good career as a driver herself and was the youngest woman driver to race at the Indianapolis 500 at just 19 in 2000. Also that year, Fisher became the first woman to stand on the podium after an IndyCar race when she finished third at Kentucky Speedway. A year later Fisher became the first woman to complete a full championship season with a best finish of second, also at Kentucky, and still holds the qualifying speed record she set on the way to getting pole position.
Such was her regard as an open wheel racer, Fisher is one of the very rare women to get a Formula One test, with McLaren, in 2002 at the US Grand Prix. Fisher continued racing until 2010 (with her own team from 2008) when she announced her retirement from getting behind the wheel to focus on owning a team.
"Some days I miss driving. One of the reasons I got involved is that I love the competition of racing, the driving, the battles and the athletic side of it, but being a mum adds a different perspective to things.
"I love being a mum but that doesn't mean I wouldn't entertain the idea of being behind the wheel again.
"Maybe in another type of car, as I couldn't really jump straight back in and be competitive - those guys are so fit and fast.
"I want to get into a situation where I can win and have fun, so it would have to be in something else. At the moment though, I'm just happy and real proud to be an IndyCar owner. If it all ended tomorrow I'd be happy with all the memories.
"It all started when my husband and I [Andy O'Gara] wanted to run at Indy in our own car, and now look where we are now. I'm so proud of what we've done," said Fisher.
If you think racing is hard work, think about trying to run a team.
The financial juggling and being responsible for team members' livelihoods, keeping sponsors happy - or trying to get new ones - the logistics of moving from one track to another, watching your car get destroyed and a myriad of other things must weigh heavily sometimes.
"Don't get me wrong, there are days when I do wonder why we're doing it, but all you need to have is a few good races and it makes it all worthwhile. And don't forget, I've been racing cars since I was 5 years old so this is all I know," said Fisher.
Her team has struggled in a few races this year but she is aware many of the more established drivers and outfits haven't had it all their own way either, including Dixon's team.
"I think a lot of Scott as a driver and a person, and I look up to him a lot. He's had a lot of bad luck this season but he just keeps on being professional and trying for the win. As we all do," she said.
