The 2014 Dodge Challenger came with several engine options, each with different horsepower ratings. There wasn't a single horsepower figure for the entire model year. To know the horsepower, you need to specify the engine:
* 3.6L Pentastar V6: Around 305 horsepower
* 5.7L Hemi V8: Around 375 horsepower
* 6.4L Hemi V8 (SRT8): Around 470 horsepower
Therefore, there's no single answer without knowing the specific engine trim level.
