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.

Chrysler 3.0L EcoDiesel V6: Autoblog Technology of the Year finalist

Offering a diesel engine in an American pickup is anything but new - Ford, General Motors and Chrysler all offer excellent and almost impossibly powerful oil-burning engines in their various fullsize trucks. What is new and novel about the 3.0L EcoDiesel, though, is its size, and the variety of vehicles that use it. It's the smallest engine, as far as displacement is concerned, currently offered in a large truck in the US, and, for 2014 and 2015, it is available in the Ram 1500 and the Jeep Grand Cherokee.
Though it may be small, it's got muscle. While 240 horsepower isn't particularly impressive these days, the engine's 420 pound-feet of torque more than makes up for that. The torque rating is even greater force than even the big 5.7-liter Hemi can muster. Chrysler's well-regarded eight-speed automatic transmission makes the most of all that bull-headed pulling power in both the Ram and Grand Cherokee. Chrysler claims the Ram EcoDiesel 1500 can tow as much as 9,200 pounds when properly equipped, which makes it "90-percent of the Hemi with a night and day difference in fuel economy."
Make no mistake; it's that promise of a sizable fuel economy improvement that many long-haul truckers will be most interested in. In the Ram 1500 that we tested for our Tech of the Year competition, the diesel engine costs $2,850 more than the gas-fed V8, and Ram estimates that EcoDiesel buyers will pay off their investment when compared to the Hemi engine in less than three years, which is considerably less time than the 4.5 or so years the average buyer will keep his or her fullsize pickup. The more you drive, the more you'll save, and the math proves equally as effective in the Jeep Grand Cherokee.
