All hail the Hellephant, Mopar's 1,000-horsepower crate engine

It's shocking to say this, but the all-powerful Dodge Demon looks weak now that Mopar has unleashed the Hellephant. This crate motor makes 1,000 horsepower and 950 pound-feet of torque, and its name is a combination of the nickname for the old 426-cubic-inch Hemi V8 and, obviously, the Hellcat. This monster is a 426-cubic-inch version of the current third-generation Hemi V8 topped by a supercharger similar to what the Hellcat line packs. Everything is cranked up to — or perhaps, past — 11. The engine block is made of aluminum and weighs 100 pounds less than the equivalent iron block. All of the internals are forged. The stroke and bore have been increased. The supercharger produces 15 pounds of boost and displaces 3 liters; more than the 2.7-liter blower on the Demon and the 2.4-liter blower on the Hellcat. And as big and powerful as it is, it will still rev to 7,000 rpm. It's a thoroughly monstrous motor, but shockingly, it won't be that difficult to live with. For one thing, Mopar will offer a complete kit to get the engine up and running, including an engine computer, wiring harness and drive-by-wire throttle. It also runs on 93-octane pump gas. That's especially amazing considering the Demon engine "only" makes 840 horsepower, and that's on race gas with 100+ octane fuel. It also has us wondering what the Hellephant could make on racing fuel. The Mopar folks did say that there's room to add more power. Pricing wasn't announced for the Hellephant engine. The Hellcat crate engine retails at $19,350 directly from Mopar, so it's safe to assume that the Hellephant will go for more. The installation kit with the computer and harness will be an extra charge of likely over $2,000, based on the Hellcat kit. The engine and the kit will be available in the first quarter of 2019.

2017 Jeep Cherokee vs. all-new Compass

If Fiat Chrysler Automobiles (FCA) can be described as on a roll, it's not by virtue of Fiat or Chrysler. The Fiat brand continues to struggle, with a restricted lineup and fragmented dealer network. The Chrysler brand is reduced to two models: an all-new Pacifica minivan and a 4-door sedan – the 300 – desperately in need of a revamp. And while Dodge is building interest via high-performance, its platforms are dated. The only real excitement is within the Ram and Jeep ranks, where global growth is fueled by cheap gas and a wealth of new intros. The newest Jeep is the Compass, and while classified as a compact, its size, interior room, and powertrain overlap nicely (or confusingly) with its midsize sibling, the Cherokee. And given their close proximity in price – the Trailhawk Compass starts in the high $20,000s while the Cherokee begins in the low $30,000s – they both could easily appear on a buyer's short list. Jeep Cherokee Trailhawk: This is an interesting crossover entry on many levels. You could begin with its polarizing sheetmetal. If, as a Jeep loyalist in 2014, you had expected the two-box profile of its wildly successful predecessor, you'd have missed the mark by an off-road mile. With a front-wheel-drive/all-wheel-drive platform housing a transversely mounted four or (optional) V6, you could store a small refrigerator in the new Cherokee's front overhang. And the previous Cherokee's slab sides and expansive greenhouse have morphed into aggressively sculpted sheetmetal and essentially no greenhouse. Yet we've grown to like it, but only as a jacked-up, big-wheeled Trailhawk. If considering the more street-oriented, front-wheel drive Cherokees, you'd do well to cross-shop. Inside, the Cherokee Trailhawk impresses. Its design and details hit above the competition, and the Cherokee won Ward's Autos 'best interior' at the time of its introduction. The Ward's team gave a shout-out to an interior "roomy, comfortable, and boldly styled with highly sculpted shapes and contrasting colors. Fold-flat rear seats add lots of utility and the Uconnect system is the best in the business." Our take is similar, and while in its fourth model year you could expect a refresh soon (make that very soon), there's little wrong with this introductory baseline. With roughly 25 cubic feet of space behind the second-row seat, you won't be blown away by the Cherokee's cargo capacity.

Jeep Wrangler 4xe's hybrid powertrain: Could it be headed to other FCA products?

On its own, the 2021 Jeep Wrangler 4xe plug-in hybrid is a big deal for the brand and the model line. It's the most powerful and most efficient Wrangler by significant margins, and it doesn't give up the off-road capability that makes the Wrangler so special. But another great thing about this hybrid powertrain is its potential to be transplanted into other FCA vehicles. Just to recap, the layout of the Wrangler's hybrid powertrain, front to back, is as follows: engine, clutch, electric motor, clutch, transmission. The engine is the same 2.0-liter turbocharged four-cylinder that's a standalone engine for the Wrangler. The transmission and electric motor are sort of one unit, with the motor and clutch replacing the torque converter of the transmission. And the transmission itself is the ubiquitous eight-speed ZF automatic gearbox. Its transmission code name is 8HP75PH. The ZF eight-speed is available in every FCA product with a longitudinally-mounted engine and rear-wheel drive or four-wheel drive, with variations in the amount of power and torque it can handle. Not only that, but the Ram 1500 and 2500 and the Jeep Wrangler and Gladiator all have powertrains that utilize the non-hybrid version of the 8HP75 transmission specifically. Even the gear ratios for that transmission as well as the 8HP70 used in the Jeep Grand Cherokee, Dodge Durango, Dodge Charger and Chrysler 300 are nearly identical to those in the 8HP75PH. And a Fiat-Chrysler representative confirmed that the transmission portion of the hybrid drivetrain is basically carry-over from the regular 8HP75. So a transplant could be a relatively simple process. As for which of these models would be the most likely to receive the hybrid powertrain first, the Jeep Gladiator and Ram 1500 would seem like good bets, since they likely have the most similar transmissions, and the Gladiator in particular because of its closely-related underpinnings to the Wrangler. Both are also highly profitable trucks that sell well and could justify the development costs of adapting another powertrain. And in the case of the Ram, there's the impending F-150 hybrid to think about. Although Ram isn't going after a fully electric model, a PHEV could be a nice middle ground. A potential limiting factor would be whether the hybrid powertrain would be sufficiently robust to handle heavy payload and towing demands, particularly over longer periods.
