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.

Government Ending Jeep Investigation

The government is closing its investigation into older-model Jeeps with fuel tanks that could rupture and cause fires. The National Highway Traffic Safety Administration said Friday it has "no reservations" with Chrysler Group's plans to recall the vehicles. The agency is expected to release a report on its investigation in a few weeks. The decision ends an unusually public struggle between Chrysler and NHTSA. The agency asked Chrysler to recall 2.7 million Jeeps last June, contending that their gas tanks - which are positioned behind the rear axle - were at risk of rupturing and catching fire in rear-end crashes. Involved were Grand Cherokee SUVs from the 1993 to 2004 model years and Liberty SUVs from 2002 to 2007. Chrysler initially refused to recall the vehicles. The company said the rate of fuel leaks and fires after crashes was similar to comparable vehicles that were sold during the time in question. It was the first time in two years that an automaker had refused NHTSA's request for a recall. Chrysler later agreed to recall 1.56 million of the Jeeps and install trailer hitches on them to help protect the gas tanks. The company sent notices to the remaining customers saying their vehicles were fine if they have factory-installed or Chrysler-made trailer hitches. NHTSA said late Friday that it has been in close contact with Chrysler and will monitor the recall as it continues. Chrysler has told customers that it will start installing the hitches soon. "Consumers should have their vehicles serviced promptly once they receive final notification from Chrysler,"NHTSA said in a statement. In its own statement Friday, Chrysler said, "We share NHTSA's commitment to safety." NHTSA's outgoing chief, David Strickland, told The Associated Press in an interview last month that Chrysler had convinced NHTSA that the Jeeps were no more dangerous than similar vehicles sold at that time. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," Strickland said. Friday was Strickland's last day at NHTSA. He is joining Venable, a law firm. NHTSA began investigating the Jeeps at the request of the Center for Auto Safety, a Washington-based advocacy group. "It is tragic that NHTSA approved Chrysler's sham trailer hitch recall for Jeeps that explode in rear impacts," the Center for Auto Safety's director, Clarence Ditlow, said Friday.
