Generally, the performance difference between a Mustang GT and a Camaro is small and depends heavily on the specific year and model. There's no single definitive answer. Different generations and trim levels of both cars have varied in horsepower and performance capabilities over the years.
To get a true comparison, you'd need to specify the exact year and model of both the Mustang GT and Camaro you're comparing. Road and track tests for specific years would then offer the best information.
