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.

Speedkore AWD twin-turbo Carbon Charger, best birthday gift ever

The backstory the Speedkore Performance AWD twin-turbo Carbon Charger teased a couple of weeks ago might be cooler than the car itself. Alan Palermo commissioned the carbon-fiber-bodied Dodge Demon Speedkore brought to SEMA last year, the one that supplanted the 6.2-liter Hellcat V8's supercharger with twin 6875 Precision Billet T4 turbos. That blasted the Demon's usual 840 horsepower up to 1,400 hp at the flywheel, 1,203 hp at the rear tires, good for an 8.77-second quarter-mile time at 162 miles per hour. Palermo's older brother remarked, "He liked the car but was more of a four-door guy," so Alan commissioned the AWD Carbon Charger as a 65th birthday gift for his sibling. Speedkore worked with Magnaflow on the sedan, starting with a 2019 Charger Pursuit as a base. The Wisconsin tuner secured a 2020 widebody Charger from Dodge, then 3D-scanned the bodywork to create the molds reproducing most of the sheetmetal in pre-preg carbon fiber. The hood, bumpers, fenders, rockers, rear spoiler, and rear diffuser are all fashioned from the lightweight stuff.  Beyond those Precision turbos laid in by Gearhead Fabrications, Speedkore installed a custom upper plenum, Boost Leash C02 progressive boost controller, custom Thitek heads, a Fore Innovations triple-pump fuel system feeding Injector Dynamics 1,700-cc injectors, and custom HP Tuners engine software calibration. Test results showed 1,525 hp at the crank when running 26 pounds of boost.  Hellraiser Performance engineered a new transmission working an FTI torque converter at one end and a carbon fiber driveshaft at the other. Instead of fortifying an off-the-shelf AWD system, Traction Products supplied a custom transfer case machined from billet shunting power to a set of Bogart Competition Series wheels wearing Mickey Thompson ET street rubber.  Speedkore fitted last year's Demon with a front-exit twin exhaust, with a single opening on each front fender, and left the rear bumper cutouts for the traditional exhaust empty. With the Carbon Charger sedan more of a family guy, Magnaflow sorted out a quad-pipe front-exit exhaust with two openings on each front fender, and ran a three-inch stainless steel Competition Series exhaust to the rear. The driver can switch between the two, the latter version providing a "moderate interior sound."  The folks at Speedkore say they'll keep tweaking the Carbon Charger after the show to get it right for the senior Palermo. We say, "Happy birthday, sir. Enjoy."

FCA inline-six rumored to be real, headed for Jeep Wagoneer

In September, Allpar reported that that clues being dropped at Fiat- Chrysler headquarters, in the carmaker's factories, and on engineer resumes pointed to the development of an inline six-cylinder engine. The site has just proclaimed the rumor is reality, writing that the straight-six, "turbocharged to meet or beat 5.7 Hemi power ratings, with a smoother torque curve, is on the way." The motor's first outing is expected to be either the next-generation Jeep Grand Cherokee, debuting perhaps next year, or the Jeep Wagoneer, debuting in 2020 or 2021. "Tornado" is the purported codename for the power plant said to be just under three liters in displacement, expanding the family begun with the Global Medium Engine 2.0-liter turbo codenamed Hurricane. Engine bay constraints and a long use horizon mean engineers won't simply add two more cylinders to the GME, however. Allpar says the brief is to keep the Tornado GME-T6 — the alphanumeric for "turbocharged six" — no more than three inches longer than the Tigershark 2.4-liter four-cylinder. That means "major design changes" that could include a space-saving head, more closely spaced cylinders, and no cylinder liners. An FCA division called Comau could be called on for its "SmartSpray" plasma lining technology. Allpar muses that the standard version of the engine for Chrysler, Dodge, Jeep, and Ram could get a single twin-scroll turbocharger. Performance trims for Alfa Romeo and Maserati could get different heads and maybe twin turbos, an SRT version might also get both those tweaks. History shows that the Italian versions would make changes to the block, as well. Even so, the Tornado would be less expensive than any Ferrari-supplied V6. A straight-six would put FCA in company with current adopters BMW and Mercedes-Benz, future users like Jaguar, and perhaps Aston Martin. The engine would span the widest range of use cases in the U.S. carmaker's portfolio, though. Potential applications include being a base engine for Ram trucks, serving double duty as a base engine and 5.7-liter Hemi replacement for the Dodge Charger and Challenger, working in the high-end Jeeps, and as a properly hot trim — with Ferrari-designed heads — in the luxury Italian sports cars. The Alfa Romeo Giulia begs for just such motivation to fill the gap between the 280-hp, $42,695 Ti Sport RWD and the 505-hp, $73,700 Giulia Quadrifoglio RWD. And a twin-turbo inline-six in a Maserati Alfieri would stack up nicely with the Germans.
