Several SRO GT4 cars in the British GT Championship

SRO GT4 is a class of grand tourer racing cars maintained by the SRO Motorsports Group that race in various auto racing series across the globe. It is an entry-level class aimed at amateur drivers. GT4 cars are production-based vehicles with a few modifications for racing. The cars are closer to their road legal counterparts than most other GT racing classes; they are also one of the least powerful GT categories. [1] [2] The class uses a balance of performance system to provide close competition between different race cars.

History

The GT4 category was founded by the SRO at the end of 2006, and first introduced in 2007, racing in the GT4 European Cup as a cheaper alternative for GT3 racing. [3] The category was also added to the British GT Championship in 2008. [4] The SRO also founded the Dutch GT Championship in 2009. [5] The GT4 class was also adapted by several other small national championships.

After an unsuccessful attempt to expand the category in 2012, the SRO introduced the GT4 European Trophy, consisting of five rounds from existing European Championships. [6] This replaced the GT4 European Cup. In 2014, this series merged with the Dutch GT4 Championship to form the GT4 European series. [7]

Due to a low number of entries, the SRO announced that the 2017 GT4 European series would be split into two championships, the GT4 European Series Northern Cup and the GT4 European Series Southern Cup. [8] The Northern Cup would turn back into the GT4 European series, while the Southern Cup would turn into the FFSA GT Championship.

In North America, IMSA allows GT4 from mainstream manufacturers in the Grand Sport class of the Michelin Pilot Challenge since 2017, and in the Grand Sport X class of the IMSA VP Racing SportsCar Challenge since its inaugural season in 2023.

Homologated vehicles

As of October 2024, over 40 vehicles have gone through the homologation project with the RACB. GT4 cars can either directly be built by the automotive manufacturer, or by race teams and tuning companies.
