When the 2015 Dodge Challenger SRT Hellcat was first revealed, its 6.2-liter supercharged HEMI seemed like a dream come true for enthusiasts and a nightmare for both the competition as well as environmentalists. After all, it didn't take long for some sites to report that, while the 2015 Dodge Challenger SRT8 Hellcat could squeeze 707 hp and 650 lb.-ft. of torque from its powerplant, it also guzzled fuel at a rate of 1.5 gallons per minute.
But now the EPA has weighed in on the matter, and there is some amount of good news: The 2015 Dodge Challenger SRT Hellcat will be able to achieve up to 22 mpg highway with its TorqueFlite 8 eight-speed automatic transmission and reach 21 mpg with a standard six-speed manual gearbox. Grades for city and combined driving were not yet available when this story went to press, yet relatively speaking, those highway marks are at the top of their class. For example, the Hellcat owns a more than 20 percent advantage in highway fuel efficiency as compared to the 700-hp rival cherry-picked by Dodge for comparison's sake.
That entry, the Lamborghini Aventador Roadster, can serve up an even 700 horses but tops out at 18 mpg. Further, the 2015 Dodge Charger SRT Hellcat showcases a starting price more than $360,000 lower than that of the Lambo.
The party line from Tim Kuniskis, president and CEO of the Dodge and SRT brands: “The new 2015 Dodge Challenger is the perfect street/strip muscle car. As the fastest muscle car ever, the Challenger Hellcat can run 10-second ETs at the track, and then get 22 miles per gallon on the drive home. With a starting price of $59,995, there’s nothing else that even comes close.”
