PHOENIX (KSAZ) - It's been nearly 10 year since Indy cars have hit the track at Phoenix International Raceway.
"It's phenomenal, I mean, it really is," Greg Fresquez said.
April 1st and 2nd, they will return and PIR spokesman Greg Fresquez says it's an experience you don't want to miss.
"They're full of speed on the throttle," he said. "They never hit the breaks, it's intense."
Crews are already hard at work prepping the pits for the Grand Prix Indy practice on Saturday.
"The pits a little different because they run different fuel in these cars," Fresquez said. "Pit stalls are larger than they do in the cup races, so there's some changes they make."
Before the Grand Prix in April, there's NASCAR in March, The Good Sam 500 taking place on the 12th and 15th.
"We call it "winterize" the track," Fresquez said. "That's more to do with the banners, that kind of thing. As far as the track surface itself, it's pretty much ready to go."
From the track to the stands, where as many as 75,000 fans will cheer on their favorite driver, race season has arrived at PIR.
Grand Prix testing at PIR is on Saturday and it's free to the fans. Gates open at 11:30 a.m., and the night session begins at 5 p.m.
