Driving with a Reynard-Toyota combination, his first Formula Nippon season was expected to be a learning year. Coronel had a relatively poor season, due to some bad luck and the team having never previously worked with a non-Japanese driver. He performed much better in the GT championship. Sharing a Honda NSX with Japanese driver Koji Yamanishi the title was in sight until the last race. Eventually they finished second when the car broke down in the formation lap of the last race.
