The 2023 Dodge Challenger Hellcat is one of the last muscle cars with an American-style V8 thunder under the hood. In its most reserved model, the Challenger Hellcat produces an impressive 717 hp from a potent supercharged 6.2-liter V8 engine. However, the Challenger has more to offer, especially in the Hellcat Redeye variant that boasts a ludicrous output of 797 hp.
