Come on... This is just flat out false. I will agree that they do better than the "peak numbers" would lead you to believe but they're consistently pretty far off the mark from the equivalent model Camaro or Mustang. The 5.7 Challengers are very competitive with or a little quicker than the 2005-2010 Mustang 4.6L 3v. I'm saying this as an avid fan of each model, an owner of two subsequent Mustang GTs and with thousands of Challenger R/T miles under my belt....also as an avid participant in the Saturday night "stoplight shenanigan" scene.
