The SRT Hellcat Redeye was developed to fill the gap left by the discontinued Demon. Its supercharged 6.2-liter Hemi makes 797 horsepower, and it debuted in the Challenger in 2019. It stops with six-piston Brembo calipers on 15.4-inch rotors. Ours is a 2020 Challenger SRT Hellcat Redeye coupe, with an automatic gearbox.
