The filing in question is titled “J1349 Certified Power Engine data for Chrysler as used in 6.2L SC HEMI (Hellcat) 2015MY Dodge Challenger 6.2L SC SRT; 2015MY Dodge Charger 6.2L SC SRT – Level 1.” Note that last part.
Dodge has refused to comment on the existence of a Charger Hellcat, but the transplant would be fairly straightforward as both Charger and Challenger share a platform.
Remember that Dodge didn’t announce a new SRT model when the rest of the 2015 Charger lineup was unveiled at the New York Auto Show back in April, leaving a gap that only a performance car can fill.
The Hellcat engine would also make the Charger the most powerful production four-door in the world. Go America.
Pricing would probably echo the difference between the base Charger and Challenger, and since the documents identify the Charger Hellcat as a 2015 model, it’s likely to make an appearance soon.
