The 2016 Pro Mazda Championship was the 18th season in series history.
Patricio O'Ward dominated the first half of the season, winning six of the first seven races (and finishing second in the remaining race), vaulting himself into a huge points lead.
However, his Team Pelfrey teammate Aaron Telitz vaulted himself back into contention by winning the next four races while O'Ward faltered.
Reigning U.S. F2000 National Championship champion Nico Jamin swept the weekend at the Mid-Ohio Sports Car Course and finished third in the championship, well back.
American Bobby Eberle won the National Class championship, largely uncontested.
