Define Gt3 Meaning

Gt3
Possibly one of the best handling cars out there, and one of the greatest car porsche has ever made (that's not a super car). The GT3 RS puts out 500 horsepower with its naturally-aspirated 4.0L Flat 6, which gives it 125 horsepower per liter. It's all about the driving experience and the gt3 is one of the best cars for the job.
