The 2019 TC America Series was the first season of the United States Auto Club's TC America Series. It was the third season of the series, originally part of the Touring Car categories at the 2017 Pirelli World Challenge, and second season as a standalone class. Under the global realignment of the Blancpain GT World Challenge America by SRO Motorsports Group, the GT4 and TCR classes are now declared separate support series, and not under the same umbrella of the World Challenge as it was prior to SRO's ownership. However, the series will continue to be part of the World Challenge.[1][2] The TCR division will include a DSG Cup for vehicles equipped with a Direct-shift gearbox.
