Detroit’s automakers are very serious about their muscle cars and the bragging rights associated with them. So you can bet Chrysler’s Dodge and SRT divisions are tired of seeing their beloved Challenger being trounced by Chevy and Ford. Whereas the top-spec Camaro ZL1 packs 580 horsepower and the Mustang Shelby GT500 boasts 650, the most the Challenger can muster is 470, even with the big 6.4-liter Hemi V8 under the hood. So what’s the answer? Well, if the ZL1 and GT500 got their figures by supercharging, so will the Challenger.
