Porsche describes the 377-horsepower GT3 RS as a racing car that is street-legal, and we believe them. As is the tradition with 911 RS models, a GT3 must undergo a serious diet before it becomes an RS. The end result is a car that is lighter, lower, and meaner than the already lightweight GT3. To keep the RS tradition alive, every GT3 RS will be white with red accents, an homage to the 1974 and 1984 RS models.
