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.

1968 Dodge Super Charger is a super Charger with a supercharger

Mopar's latest custom creation is sure to be in the running for coolest car at this year's SEMA show. It's a 1968 Dodge Charger, a car selected in part because this year marks the car's 50th anniversary, but taken to the extreme and renamed Super Charger. The headliner of the car's radical upgrades is the new "Hellephant" engine. It's a take on the original car's 426-cubic-inch Hemi V8. But this new engine, with the same displacement, is based on the current Hemi V8, and adds a supercharger. All told, it makes a whopping 1,000 horsepower and 950 pound-feet of torque on 93 octane pump gas. It will be available as a crate engine, too. The engine is far from the only impressive change to the car. All over the body are mild to wild tweaks. The wide, uninterrupted grille from the original is still here, but it's a one-piece example now. And instead of hiding the headlights behind doors that have to open for illumination, the lights simply shine through the grille, retaining a clean look even at night. The whole car sits 2.5 inches lower than stock, and it's now four inches wider thanks to the huge fender flares. They house 305-mm-wide tires up front, and 315-mm tires in the rear. Likely the most complicated change to the car is the lengthened wheelbase. There are two more inches between the wheels now, something Mopar did to reduce the front overhang. A close second in complexity are the taillights. They're the same shape as the originals, but now the round elements are actually exhaust outlets. The tips also happen to be the same as those on the Alfa Romeo Stelvio. There are other details that help bring together the exterior. The rain rails have been smoothed out on the roof, the vent windows removed, special 426 stickers have been added, and the fuel door now has a Hellephant badge with a blue background with lots of little Mopar Ms. The interior gets some attention, too. The rear seat has been removed, Dodge Demon style. It gets a custom roll bar designed to be as unobtrusive as possible, even getting the hoop around the seats to roughly line up with where the windows meet. Gauges come from the Mopar catalog, and the steering wheel and seats are from the dearly departed Dodge Viper. They're particularly relevant, as the six-speed manual transmission comes from the Viper, too. Related Video: This content is hosted by a third party.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
