In 2015, the Dodge Challenger SRT Hellcat hit the road for the first time. It had an amazing 707 horsepower.

Some people who stuck with it liked it right away, while others didn't. In just eight years, the Challenger SRT

Hellcat's horsepower went from 707 to 807. This is about

the same change in power between the fifth and sixth

generation Shelby GT500s. Even though it had more speed,

the Dodge Challenger SRT Hellcat didn't really go any faster than when it first came out.
