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.

This Dodge Challenger was stolen, used in police chases and recovered all in the week before its SEMA debut

Most of the drama in a SEMA build is in getting the car ready in time for the big show. That was all Quintin Bros Auto and Performance was expecting when they built a supercharged Dodge Challenger Scat Pack with custom carbon fiber body parts, aftermarket wheels and upgraded brakes. But unfortunately, a bigger drama happened in the week leading up to the show. And it was the worst kind. As part owner Pete Quintin told us, the car was shipped out in a small trailer, and while the delivery driver was spending the Monday night a week before the show at a hotel, a thief showed up in a stolen pickup and made off with the trailer and the car. It wasn't an easy task, either, as the delivery driver had parked the trailer in with the truck blocking it. The thief used his own (well, not his own, but you know what we mean) truck to shove the trailer hitch out where he could access it, then hooked it up and took off. Several miles down the road, he parked, opened up the trailer and vanished in the Challenger. The following morning, the delivery driver discovered the theft, and Quintin Bros immediately informed the owner so that a police report could be filed and a search could begin. The trailer was found not too long after, thanks to someone who was following the story on social media. But obviously the car was missing. Folks on social media were also helpful in tracking the car, in addition to the help of the Las Vegas Police Department (LVPD). What followed was a week of chasing the car down. Twice the car was found in parking garages, Quintin said, and both discoveries resulted in police chases. The second chase was the most dramatic, with a police officer stopping after noticing the car. The thief was in it, and he bolted upon seeing the officer. He powered the Challenger right through the nose of the police car, damaging both. The chase culminated on the highway, where Quintin told us 14 cars were in pursuit, and the thief got up to 150 mph. Police ended up calling off the chase because of the danger. But the car was damaged enough that the thief eventually abandoned it at one last garage, where it was picked up on Thursday. Once the car was recovered, things gradually began looking up for the Quintin family. Pete Quintin said that as soon as LVPD found out the Challenger was meant to go to SEMA, the department got the car out of evidence impound as fast as it could so the shop could show off the beat-up car.

Chrysler expecting up to 200,000 9-speed transmissions for 3 models this year

Striving for improved fuel economy, we already knew that Chrysler will begin using a nine-speed automatic transmission in some of its new products this year, but what we haven't known is that volume at which this gearbox will be used. According to Bloomberg, Chrysler CEO Sergio Marchionne has been quoted as saying that the automaker expects to sell close to 200,000 units equipped with this new transmission in 2013. Those gear-rich trannies will be spread out across three models, consisting of the redesigned Chrysler 200, the still-unnamed Jeep Liberty replacement and the Dodge Dart.
This transmission should play a pivotal role in making Chrysler vehicles more competitive in their respective segments. Just for comparison, one of the Dart's key competitors, the Toyota Corolla, still uses a four-speed automatic, and a previous report indicates that the next-generation 200 could get up to 38 miles per gallon on the highway, which is better than most non-hybrid midsize sedans on the market. Marchionne says that the new Jeep model is expected during the second quarter of this year, but there is no word as to when the new 200 or nine-speed Dart will debut, but clearly Dodge would like to have the transmission in its compact yesterday. As for that volume figure, it definitely doesn't seem out of reach since the Dart, Liberty and 200 combined for a total of more than 225,000 units in 2012.
How many more gears can we expect in future cars? Probably not many more, since the CEO of transmission-builder ZF, Stefan Sommer, previously stated that nine speeds was the "natural limit" for transmissions.
