IndyCar is returning to Phoenix International Raceway for the first time in more than a decade. Before the series goes racing in the desert, the stars and cars will wind it up for a two-day test.

The last time the Verizon IndyCar Series was at PIR, it was 2005 and Sam Hornish Jr. took the checkered flag driving a Toyota for Team Penske. Things have changed. Now, the engine battle is between Honda and Chevrolet and Hornish isn’t driving in the series.

Phoenix International Raceway is a little more than a mile long, but the track itself has a rich history with IndyCar. Prior to the series’ departure in 2005, the speedway had hosted an IndyCar event dating back to the United States Auto Club days in 1964. Al Unser Sr. has the most IndyCar wins at the track, but the long list of winners includes plenty of top names like A.J. Foyt, Jimmy Bryan, and Mario Andretti.

Here’s what you need to watch for when the Verizon IndyCar Series makes its return to Phoenix.
