The GT4 America Series is a sports car racing series based in the United States. In 2019, the series was relaunched with the explicit GT4 title, following the alignment in 2017 of the Pirelli World Challenge series “GTS” class with SRO GT4, and the Stéphane Ratel Organisation assuming control of the series in May 2018. It is a GT World Challenge America support series, managed by SRO and sanctioned by the United States Auto Club.

GT4 America is available FREE on SPEED SPORT 1.
