The Last of a Breed
The company plans to produce a limited number of production X132 Hellcat Combats next spring. Confederate's founder and CEO, Matt Chambers, says the production version of the X132 Hellcat Combat will be the last of a breed.
"There will be no more big block Confederates after the Combat examples are produced next spring. These examples, represented by the experimental Combat prototype, are going to be the end of an era for massive displacement American V-twins packaged as fully structural components within a billet case and handmade chassis. No expense will be spared in our effort to memorialize this passing as the definitive exclamation point."
