The Challenger won the J.D. Power and associates award for most appealing mid size sporty car so if Marchionne would put more hp under the hoods of the Challenger I think that it would do a lot better plus Marchionne said that he wants to make Dodge a performance oriented brand which is one of the reasons he split the Ram trucks into their own division. That leads me to believe that the Challenger is going to survive the next restyling.
The Camaro is not going away anytime soon, but they need to change the interior that thing is just terrible. Besides the performance and the side profile there is no way I would even consider owning one.
