GT3

GT3 is an abbreviation that may refer to several distinct topics in motorsport and popular culture. In professional racing, GT3 denotes a class of production-based grand tourer cars built to a common set of rules. Originating with FIA GT3 regulations and now administered by the SRO Motorsports Group, the category emphasizes close competition through balance of performance and cost controls. GT3 cars are typically customer-run race cars derived from road-going models, and the class is used across many national and international series, including the GT World Challenge events.

GT3 also refers to the Porsche 911 GT3, a line of high-performance, track-focused variants derived from the 911. Introduced to emphasize driving dynamics and lightweight engineering, GT3 models feature enhanced aerodynamics, reduced weight, and more powerful, naturally aspirated engines compared with standard road cars. The GT3 designation signals a shift toward precision handling and track capability, and the models have become a core part of Porsche’s strategy that links production cars to motorsport derivatives, including high-performance race variants such as the GT3 RS.

In gaming, Gran Turismo 3, commonly abbreviated GT3, is a 2001 racing video game in the Gran Turismo series for the PlayStation 2. Developed by Polyphony Digital, it expanded the series with a broader car roster and more advanced driving physics for its time, contributing to the series’ reputation for realistic simulation and authentic driving experiences.
