The 2019 Pirelli GT4 America Series was the inaugural season of the GT4 America Series . It took over the GTS class of the Pirelli World Challenge, which adopted global GT4 technical regulations in 2018, and it is a Blancpain GT World Challenge America support series. GT4 America Series is split into a Sprint series, which features 50-minute races with one driver per car, and a SprintX series, which features one-hour races with two drivers per car and a mandatory driver change during Pit stops. Also East and West regional championships are awarded. The season began on 2 March in Austin and ended on 20 October in Las Vegas .[ 1]
