I think that the Hellcat
I think that the Hellcat engine is simply amazing. The idea that you can have a 700-800+HP warrantied, factory engine that reliably runs off of pump gas is unprecedented, especially in a reasonably affordable car (not a $$$ exotic). It is natural that the Challenger's sales numbers have fallen off since it was first released. Dodge has really done little to update the Challenger and Charger for several years now beyond the awesome Hellcat motor. The Demon was also a first, having a factory drag racing car that was also (truly) street legal. The Widebody model stuffed fatter tires in the car, and the Redeye gave us almost all of the power of the Demon without the compromises and at a lower price. I still think that Dodge should offer the Redeye engine on all of the vehicles that can fit it under their hoods, from the Challenger and Charger, to the RAM trucks, to the Durango, and of course the Jeep Trailhawk. Until the PSA/FCA merger finishes, and Chrysler has to start thinking about building some competitive economical cars like all the other automakers, their unique superpower is their super-powered engines.
