Ford released the official horsepower rating of the GT500 at the Detroit Auto Show. 475hp is what they are listing it at. I'm willing to bet on dynos that it will be even higher. The engine in the GT500 is more or less the same engine used in the GT, only a different supercharger. The GT is listed at 550hp, but dynos have shown it to be closer to 600hp.
The R/T will not be meant to compete against the GT500, that will be the SRT versions job once it's produced.
I also think after it's all said and done, and produced on the new LY platform, that the Challenger will weigh very close to the GT500.
