You're making the same mistake so many other people are making. You're regurgitating the "Hurricane is superior!" myth based solely upon ONE metric: horsepower on paper.
Here's the reality: the Hurricane engine, like most engines from Europe, has been littered with problems. And, since it's significantly oversophisticated, those problems are expensive and time consuming to repair. Fourteen hours to do a water pump?? Twenty-two hours to do a timing chain?? It's just madness. Wait until those engines are out of warranty. People will be mad as hell. Then let's talk maintenance. Have you seen under a Ram/Wagoneer lately? Because of the twin turbo exhaust routing, you can't even service the transmission fluid without removing the exhaust. And you can't pull an engine dipstick to visually inspect oil condition. We won't even go into the way the engine sounds like a Hoover vacuum cleaner, or the way it drinks fuel like it's sponsored by OPEC with a trailer behind it or when the throttle is mashed for fun. When you get time, go over to the Jeep Wagoneer forum and poke around in the "problems/issues" section. HOURS of reading.
There is not a chance that the Hurricane is "superior" to the Hemi. In no category. There will never be a Demon with a Hurricane engine running 9.65 in the 1/4 mile. There will never be a Hurricane that gets significantly better fuel economy than a V8. There will never be a Hurricane that routinely shows more longevity than a V8. There will never be a Hurricane that puts a smile on the driver's face upon pressing the ignition start button on a cold morning. There will never be a Hurricane that provides the linear, smooth driving experience of a Hemi. There will never be a Hurricane with the resale value of a V8. There will never be a Hurricane that a person can work on at home and keep on the road for decades like a V8. It's just not going to happen.
The fact of the matter is that CDJR had two options: keep paying for carbon credits and EPA fines while simultaneously selling vehicles like hotcakes, OR ditch the V8s in favor of lower emissions at the risk of gutting their sales and ruining the company. Unfortunately the idiot who was CEO at the time chose the latter. And now it's upon Mr. Kiniskis to try and save the ship....and he's doing it the best way; by bringing back the powertrains that people want.
