Based on the McLaren 570S sports car, the 570S GT4 is a ready-to-race model modified to meet the requirements of the GT4 FIA class. The model was released in 2017 and features the same 3.8L mid-mounted and twin-turbocharged V8, nestled in a carbon fiber chassis that is standard on the street version. However, McLaren supplies the GT4 to customers with an altered suspension, magnesium center-locking rims, an upgraded engine cooling system, and a racing aero package on its body. Customers can even upgrade to the Sprint package that disregards all FIA standards.
