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.

UAW papers reveal release dates for new Dodge, Jeep and Ram models

Documents published by the United Auto Workers union reveal key information about some of the products Dodge, Jeep and Ram will release during the early 2020s. All three brands will try to capitalize on the growing demand for trucks and SUVs in the United States. The agreement between the UAW and Fiat Chrysler Automobiles (FCA) outlines what the period between 2019 and 2023 will look like from an employee's vantage point. The $4.5 billion factory the automaker is building in Detroit will begin manufacturing a three-row Jeep model in 2020, and it will add the next-generation Grand Cherokee to its roster the following year, according to CarScoops. The new Grand Cherokee will also roll out of the Jefferson North facility that makes the current model scheduled to retire shortly before its successor arrives. The Dodge Durango will continue to be built there, and the UAW papers mention a mild-hybrid variant of the SUV due out before the end of 2020. Two body-on-frame Jeep models tentatively scheduled to revive the heritage-laced Wagoneer and Grand Wagoneer nameplates will break cover in 2021. They will be built alongside Ram pickups at the Warren Truck plant, and odds are the three models will share several components under the sheetmetal. Adding the two Jeep models is expected to create 1,400 jobs, FCA predicted. Speaking of Ram, the high-performance TRX model (pictured) aimed at the Ford F-150 Raptor's jugular is penciled in for a 2020 launch. The concept that previewed the model made its debut in 2016, so it's reasonable to assume it will have changed considerably by the time it reaches showrooms. It will be based on the newest variant of the 1500, not on the last-generation model still sold as the Classic. What won't change is the supercharged, 6.2-liter Hellcat V8 between its fenders. The plug-in hybrid Wrangler remains on track for a 2020 launch. The Cherokee will continue to come out of Belvedere Assembly in Illinois, but the UAW's documents mention "fresh models / features" off of its unibody platform. Whether that means new trim levels or additional body styles remains to be seen, but it sounds like something new and Cherokee-related is around the corner. The ancient Dodge Journey shares at least one thing with the beater you drove in high school: a four-speed automatic transmission. The gearbox is finally on its way out, according to the UAW, and the 2.4-liter four-cylinder engine that powers the entry-level model isn't long for this world, either.

That thing got a Hemi? Mopar engine kits make it easier to say yes

Thanks to a new kit from Mopar, classic car owners will have an easier time dropping Hemis into their muscle cars. The kit works with Mopar's 345 and 392 Hemi engines (5.7 and 6.4 liters respectively) and with cars built before 1975. The kit will run $1,795 and has everything needed to get one of the above engines running. The parts include a power distribution system, engine computer, engine and chassis wiring harnesses, O2 and intake air temperature sensors, ground wiring and a gas pedal. The kit is also designed to work with a manual transmission, but Mopar says a transmission such as the Torqueflite 727 and 904 can be made to work with the system. As for examples of the kit in action, take a look at the Jeep CJ66 and Dodge Challenger Shakedown that Mopar revealed this week at the SEMA show. Mopar also offers a few other parts to help complete the project, including various oil pans to clear subframes, a set of headers, and accessory drives for power steering and air conditioning. All of these parts are extra cost though. You'll also need an engine, and the 345 starts at $6,070, and the 392 runs $9,335. However, if you happen to already have one from 2014 or newer, that will work, too. Muscle car fans are getting more choices for their engine conversions. Chevrolet Performance already sells crate engines with "Connect and Cruise" kits to get its engines working in classic cars. The General also offers it with more engines. However, for people who want to keep a Mopar engine in their classic Chrysler, Dodge, Plymouth, or Jeep, this is a cool new option.
