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.

2014 Ram Promaster recalled over brake hoses

It's barely been a year since Chrysler brought the Fiat Ducato over to these United States as the Ram Promaster, but already it's being subjected to its second recall - both of them revolving around essential controls that are critical to the vehicle's operation.
The first came less than a month ago, when the National Highway Traffic Safety Administration issued a recall for nearly 10,000 of the vans due to a sticky accelerator pedal. Now Chrysler has issued a second recall to deal with the brake hose.
This second recall affects some 6,800 units of the ProMaster, half of which Chrysler says are on dealer lots. The automaker is instructing dealers to inspect both the vehicles it has in stock and to bring in customer vehicles to perform the same check, to ensure that the brake hose was properly installed in the first place. If not, the brake hose will be replaced.

2014 Ram ProMaster 2500

Front-wheel drive is what sets the all-new Ram ProMaster full-size commercial van apart from its competition. In a segment still choked with thirsty, rear-wheel-drive, ladder frame, pickup truck-based cargo vans, the American automaker is introducing something entirely new - well, new to our domestic market, as Europeans will recognize Ram's fresh entrant as a made-for-USA Fiat Ducato.
While the big ProMaster doesn't have a traditional body-on-frame chassis, it isn't a pure unibody either. Consider it a hybrid of both, with a unibody cab up front and a reinforced high-strength steel subframe in the rear. The platform employs double A-arms and MacPherson struts on the front axle, while the rear uses a simple tubular beam axle. Tires are 225/75R16 at all four corners. The steering is hydraulic rack-and-pinion (allowing an impressive 36-foot turning radius) and there are disc brakes with two-piston calipers all around. It is a solid, if unsophisticated, setup.
This game-changing van, which has already arrived in showrooms with a starting price of $28,630, is propelled by either a gasoline-powered 3.6-liter Pentastar six-cylinder (280 horsepower and 258 pound-feet of torque) or a new turbocharged 3.0-liter four-cylinder diesel (174 horsepower and 295 pound-feet of torque). Ram will offer a traditional six-speed automatic or a new six-speed automated single-clutch manual transmission that drops the hydraulic linkage to improve fuel economy - details are still emerging on this unique gearbox.
