2016 International Formula Reject Challenge season

The 2016 International Formula Reject Challenge season was the first season of IFRC, a new series created to fill the void created by the cancellation of Rejects of LFS due to serious safety concerns. The drivers' championship was won by Terry Hawkin, while Lavezzi IBR were the teams' champions.

It would turn out to be then only season run under the IFRC name, as the name was changed to AutoReject 3.5 in 2017 to avoid a lawsuit by a charity organization that uses the same abbreviation, as well as making the series' name uniform with AutoReject 2.0, formerly F1RDS.
