The Charger weighs in at an astonishing 4600 pounds, nearly as much as my GC R/T. Shedding 100 pounds off it is meaningless. Shedding 1,000 off it would be more of what it needs.
Regardless of weight, hp numbers matter to a lot of people. This isn't just "internet testing" and such, these are the numbers on the sticker on the vehicle sitting on the dealer lot. Stock. 426hp on the Camaro SS, and 420 on the Mustang GT. 440hp on the high-output Boss 302. 370hp stock on the Charger/Challenger R/T pales in comparison to these numbers. The SRT is not comparable to these models, it's comparable to the top-level models of each, and Ford and Chevy are miles ahead with the ZL1 and the GT500 not even being able to closely compared to the current SRT (though the supposedly upcoming blown 6.2 would bring it closer).
When looking at what is currently being sold, 370 pales in comparison to 426 and 420. Both of the stock Chevy and Ford easily out-accelerate a Charger/Challenger in 0-60 (5.2s in Charger (AWD) 5.4s in Charger RWD, vs. 4.8s in Camaro and 4.5s in the GT and 4.0s in the Boss 302) and quarter mile times. Dodge needs to do something to up its game. They're falling behind. Way behind. And not just in the $55-65k range. They need to up what average people like to buy.
