I'm sorry but Mopar's power numbers are slightly irrelevant. The SRT8 Challenger boasts a nice 470hp, and only barely beats out a bone stock 5.0 in the quarter mile. IMO, it's not worth the extra pricetag attached to it. That being said I would have to imagine the 650hp Shelby would stomp all over this Hellcat, and that's the 2014 model. The 15 I'm sure is going to be even more fierce, I would think.
I'm not slamming it, I think the Challenger was the best rendering of a classic muscle car that any car company has done. It's just not as fast as some of the other muscle cars out there, due to it's power to obsessive weight ratio. Still, cool looking car. It's insane how much power cars are coming off the showroom floor with these days
