Mecum Report: 2015–2023 Dodge SRT Challenger Hellcat | 707/717 HP 
Dodge has been accused of keeping its L-car platform alive well past its shelf date—a complaint we’ve never given credence to at HOT ROD—and this has resulted in a huge fleet of Hellcat Hemi-powered Challenger V-8 muscle cars out in the wild, which is actually a super good thing. Moreover, with the more desirable widebody variants like the Demon, Redeye, and Demon 170 commanding all the attention and the highest resale/auction dollar amounts, the narrow-body 707-/717-hp Hellcat Challenger has become a widely available highest-horsepower car with enough available inventory to keep competitive bids—and price gouging—in check. In our research of auction results over the past two years.
