2015 Challenger SRT Hellcat Delivers EPA-Rated 22 MPG Highway

Most customers purchasing a 2015 Dodge Challenger SRT Hellcat aren’t likely considering fuel economy as a reason for wanting one of the most brutal machines ever assembled. That said, the pony car is fairly efficient on the highway in comparison to more exotic fare.

The lieutenant to the Charger Hellcat’s general, the Challenger Hellcat delivers an EPA rating of 22 highway via its eight-speed TorqueFlite automatic, losing only a single mpg for those who opt to row their own boats through a six-speed manual. Chrysler notes the highest rating comes from the auto’s 7.03 gear ratio spread, allowing the elephant to be that efficient on the highway more often.

In comparison, exotic beasts like the Lamborghini Aventador Roadster, Aston Martin Vanquish and Mercedes-Benz SLS AMG GT deliver similar amounts of firepower to the battlefield, but only manage to put out 18 mpg to 19 mpg in so doing.

Furthermore, unlike the six-figure price tags for said exotics — of which only the Aventador comes closest in matching horsepower with the supercharged 6.2-liter HEMI Hellcat, the others falling just under 600 horses — the Challenger comes in at just under $60,000. Not a bad place to be, one would suppose.

Figures for city and combined mpg were not announced as of this writing.

    Jay Leno did a feature on his original Hemi (426) Challenger, and I believe he said the best MPG he could expect was about 8, so this is almost 200% better with about 50% more power and much better drivability. We are living in the golden age of performance.

    Off boost and on the bypass it takes little power to run the blower and the air/fuel mix can be dialed back as well. Hellcat owners with a light foot will probably report even better numbers.

    And by simply running it in all-cylinder deactivation mode, powering it up to EPA test speeds with a tiny scooter motor in the trunk, it could get 50!! Yeah! aren't we being all relevanty and stuff...!!!

    My 2008 IS-F got 27 mpg hwy with summer gas, so I'm honestly impressed with the mileage numbers for an engine with a 300+ hp advantage. As others have mentioned, it wouldn't be surprising to hear reports of 24 mpg hwy after break-in (and before mods LOL). Kudos to Dodge for their design effort...
