The 2015 Dodge Challenger SRT unveiled today is Chrysler Group’s first use of a new 6.
2-liter supercharged V-8 engine rated at more than 600 hp to take on the Ford Mustang GT500 and Camaro ZL1.
The motor, known as the Hellcat, is expected to rival that of the 640-hp, 8.4-liter naturally aspirated V-10 that powers the automaker’s halo car, the 2014 SRT Viper.
According to the automaker’s five-year business plan, the supercharged Hellcat is expected to migrate to other SRT vehicles, including the Charger SRT. The Hellcat is undergoing final calibration and does not yet have a specific power rating, a Chrysler spokesman said.
