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.

Driving the Jeep J6, Shakedown Challenger and other Mopar concepts

Mopar has been a one-stop-shop for factory-backed performance modifications and accessories on FCA products for a long time now. You want a 707-horsepower engine for your old Plymouth Belvedere? Mopar has you covered with the Hellcrate. Maybe you want a lift and off-roading lights on that newly-bought Wrangler? Mopar can accommodate those wants (or needs, we don’t judge) as well. We get to see some of the companyÂ’s weirdest creations every now and then, but rarely do we get the opportunity to drive the FCA Mopar concepts. ThatÂ’s what made this past Woodward Dream Cruise so special: We got to rip some of MoparÂ’s finest and most recent creations up and down Woodward Avenue. Everything from a 1971 Challenger restomod to the brand-new Easter Jeep Safari J6 concept was in attendance, so letÂ’s get right to it. Mopar Woodward View 6 Photos 1967 Plymouth Hellvedere This car is near the pinnacle of what you can do with off-the-shelf Mopar purchases. It was only a humble 1967 Plymouth Belvedere before Mopar dropped the 707-horsepower supercharged V8 from the Hellcat into the engine bay. Sound ridiculous? Yeah, it is. Other parts of it are new as well, including the disc brakes. Good call. However, Mopar didnÂ’t remove the classic car charm from the entire driving experience. The steering, for example, is surely as slow and inaccurate as it was back in 1967. That doesnÂ’t help matters when youÂ’re trying to put 707 horsepower to the pavement with less-than-ideal rear rubber. Floor it in damn near any gear of the Tremec six-speed, and the front end rises straight up as the rear kicks sideways with the force of many mules. There are no electronics such as traction control or stability control to step in and wrangle the car into submission. But hey, who wants them, anyway? The question remains: Should you buy a Hellcrate engine for your classic? If money were no object, the easy answer is yes. Have at it so long as you love smoky burnouts and excessive amounts of horsepower. Just make sure you know how to deal with that much power before you stick your right foot in it.   Dodge Challenger Shakedown View 15 Photos 2016 Dodge Shakedown Challenger Concept WeÂ’re going downhill in horsepower with this restomod, but the drivability and ease of driving goes way up. Dodge showed this “Shakedown” concept at SEMA awhile back, and as with most concept cars, getting a chance behind the wheel is a special opportunity.

Mopar Hellephant crate engine sells out in 48 hours

This happened so quickly that we're only just catching up with it. Mopar opened pre-orders on the 7.0-liter Hellephant Hemi crate engine on April 26, which is Hemi Day. According to Allpar, hubbub on social media not long after that day claimed Mopar had gone through all of its Hellephant stock. When Allpar asked Fiat Chrysler for clarification, a spokesperson e-mailed, "Given the high demand and the hand-built, time-intensive build process, we have closed preordering for the 426 Hellephant Supercharged HEMI crate engine. Based on preorders, the engine sold out in just two days. Customers can visit www.cratehemi.com to receive future information and updates on the 'Hellephant' engine." No one is certain how many engines Mopar sold. Allpar wrote, "Industry insiders believe Mopar may be making around 100," but reiterated that it's a guess. The engine and the ordering process have their peculiarities. Mopar Insiders explained that Tool Engineering International helped create the 426-cubic-inch block, and that the Hellephant engine "shares nothing except for displacement with the rumored upcoming 7.0-liter 426 Hemi V8." On the Hellcat.org forum, a poster wrote that the engines "can only be sold through a dealer and that the dealers can only order 1 engine per week." The Hellephant doesn't come with Mopar's three-year, 100,000-mile warranty, either. During a press briefing last October, FCA officials said they weren't sure about offering any warranty. Based on the motor being given a part number starting with the letter P, there is a bit of protection, but it's a 90-day limited warranty covering "defects in materials or wokmanship," and only applies to engines not used in competition. For those who didn't get the opportunity to drop $29,995 for 1,000 horsepower and 950 pound-feet of torque, the best bet is to hope for the return of Apollyon's pachyderm. Motor1 wrote that "Rumors hint at... another limited run scheduled for next year due to overwhelming demand." That's thin thread to hang a Hellephant from, but it beats bupkis.
