Hennessey’s Dodge Challenger SRT Demon 170 Will Push Up To 1,700 Horsepower

The cars they create will be low-volume, ultra-high-horsepower builds like no others.

“Demand for our powerful vehicles over the past several years has been so strong that we had to shift from being a high-volume tuning company to more of a factory with assembly lines and all of the logistics that go with delivering over 500 vehicles per year,” said Founder and CEO, John Hennessey.

But that left a gap in the market for the extreme, high-horsepower builds that made the brand famous, which is a niche HSO aims to fill.

“We are happy to announce that we’ve created a new division within the company that allows us to build mega-powerful vehicles in small production runs,” explains Hennessey. “Taking my new Dodge Demon 170, removing the blower, adding a pair of turbos, and increasing power from 1,025 to 1,700 horsepower was exactly what we’ve been wanting to do.”
