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.

Crawling Moab in the 2015 Jeep Renegade Trailhawk [w/video]

The funny thing about the Renegade Trailhawk is that Jeep still feels the need to defend it. For the past 20 years, automakers have sent emissary vehicles outside the citadel walls surrounding their brand niche. In doing so, these companies found buyers eager to join the cult instead of an angry horde. With the kingdom successfully expanded, automakers had to build new walls to contain this broader identity. This is the story of Jeep's modern expansion, growing with new models while the faithful at the brand's center howl at every quest into broader market segments. Thirteen years after it busted out the Liberty and eight years after birthing the Compass and Patriot, you'd think the resistance to new Jeeps would subside. But no. It's 2015, and while nobody makes the slightest tantrum over BMW's new minivan (except for Sniff Petrol), the Renegade still has to fight its way through pitchforks and torches. Which is a long way of saying that this author is guilty of brand prejudice, too. When the company told us that we'd spend the first day of the Easter Jeep Safari driving seven awesome concepts and the second day driving the Renegade Trailhawk on Dome Point Trail, we could only think, "They giveth excitement, and they taketh it away." Our pessimism was later proven to be incorrect. Sharing the sentiment our colleague Brandon Turkus expressed after his Quick Spin, we found the Renegade to be "in a word, impressive." Dome Point will not trouble a kitted-out Wrangler, but in a compact SUV with on-road tires the rocky sections were chunky enough to require close attention to your lines or use a spotter. As instructed, we put the little 4x4 into the Selec-Terrain's Rock mode, and with common sense plus one eye on the man directing us with hand signals the Renegade climbed over everything with some wheelspin but little fuss. At the first rest point, we turned the car off to wait for vehicles behind. Not realizing that this resets the drive mode to Auto, we crawled through the next two rocky jumbles in the default setting. The result was the same: a bit of wheelspin climbing over thick steps, but an altogether drama-free passage. Auto mode can't use the engine throttle maps unique to each Selec-Terrain setting, but it doesn't hamper the Renegade's capability by much. On a steep bit of trail with a crest capped by stacked stone plinths, it took three tries to find the right line, but that's on us – the Renegade did more than expected.

2.1 million vehicles recalled again over faulty airbags

Fiat Chrysler Automobiles, Honda and Toyota will recall 2.1 million vehicles to fix faulty airbag modules "after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles." These vehicles had all previously been recalled, but the National Highway Traffic Safety Administration found that the airbags could still potentially malfunction. This recall will cover Acura MDX, Dodge Viper, Jeep Grand Cherokee, Honda Odyssey, Pontiac Vibe, Toyota Corolla, Toyota Matrix and Toyota Avalon models made in the early 2000s. NHTSA has reportedly received about 40 reports of airbag deployment in such vehicles, even though the vehicle had not been involved in a crash. Roughly one million of these same vehicles, all from Honda and Toyota, are also subject to recalls due to faulty Takata airbag modules, though this particular recall is for "an electronic component manufactured by TRW" that is separate from the actual airbags from Takata. According to NHTSA Administrator Mark Rosekind: "This is unfortunately a complicated issue for consumers, who may have to return to their dealer more than once. But this is an urgent safety issue, and all consumers with vehicles covered by the previous recalls should have that remedy installed. Even though it's a temporary solution until the new remedy is available, they and their families will be safer if they take the time to learn if their vehicle is covered and follow their manufacturers' instructions. A hassle is much better than a family tragedy." If you're the owner of an affected car, expect to hear more from the official automaker and government channels in short order. In the meantime, we'd suggest getting your car checked and fixed at your local dealer. The official statement and recall information can be found below. Previously Recalled Vehicle Remedies Not Working as Designed; NHTSA Announces Follow up Recall of 2.12 Million Cars and SUVs Saturday, January 31, 2015 Contact: Gordon Trowbridge, 202-366-9550, Public.Affairs@dot.gov WASHINGTON – U.S. Transportation Secretary Anthony Foxx announced today the recall of more than 2.12 million Acura, Dodge, Jeep, Honda, Pontiac, and Toyota vehicles for a defect that may cause airbags to deploy inadvertently. The recalls will provide vehicle owners with a new remedy after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles.
