More powerful than the Hellcat, the new Dodge Challenger SRT Hellcat Redeye produces a whopping 797 horsepower (594 kilowatts) and 707 pound-feet (958 Newton-meters) of torque courtesy of a supercharged 6.2-liter V8. It’s the most-powerful production Challenger ever built. Production of the updated Challenger lineup will kick off at Dodge’s Brampton Assembly Plant this fall. Deliveries are scheduled in the fourth quarter of the year.
