The 2021 Dodge Charger SRT Hellcat Redeye is the range-topping version of Charger four-door sedan lineup. An upgrade to the more familiar Charger SRT Hellcat, the Redeye borrows its looks, drivetrain, and technology from the Challenger SRT Hellcat Redeye. And just like the coupe, the sedan includes drivetrain components from the Challenger SRT Demon. Since there won't be a Demon version of the Charger, the 2021 SRT Hellcat Redeye is the most powerful version of the American sedan. What's more, it's also the fastest and most powerful mass-produced sedan in the world. Let's find out more about it in the review below.
