2018 Jeep Grand Cherokee TrackHawk shows off its hellish supercharged V8

We've seen the spy shots of this thing, the 2018 Jeep Grand Cherokee TrackHawk, before. But only from the outside. The external changes are plenty telling, but there was always the slight chance we were looking only at an extra-hot SRT version, not a full-blown (pun intended) TrackHawk with a Hellcat motor. Until the hood goes up, there's no telling what we're really looking at. Well, seeing is believing. We have been looking at TrackHawks all along. And Mike Manley, Jeep's CEO, wasn't selling the world a bill of goods when he said to expect the thing "by the end of 2017". As you can clearly see in the slightly noisy engine shot, that's a supercharger parked on top of FCA's 6.2-liter V8, just like in the Charger and Challenger Hell-twins. Chances are it'll make the same power as it does in those two – 707 hp, in case you're just waking up from cryo-stasis and aren't aware of the most famous power output figure on the planet. There are some differences between this Grand Cherokee and ones we've previously pegged as TrackHawks. The fog lights in the lower grille vents are gone, and the rear fascia gets a bit more aggressive. Perhaps these will be the external details that separate the TrailHawk from the lowly non-supercharged SRT versions. We've also been hearing about quad exhaust tips, but haven't seen them on a prototype yet. If Jeep wants to get this thing out on the road by the end of the year, we're likely to see it coming to an auto show soon. Keep your eyes peeled. Related Video:

Your 2018 Jeep Wrangler can already be fitted with a Chevy LS V8

Over a long enough period of time, every car model on the planet will probably have at least one example receive a Chevrolet V8. And a large number of them will have an LS-series V8, commonly found in Corvettes and Camaros from the last 20 years (plus other GM vehicles in slightly different forms). Sometimes it doesn't take very long, as is the case with the 2018 Jeep Wrangler JL. The new Jeep has only been available for a couple of months, and already a company called Bruiser Conversions is offering to install LS engines under the hood. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Specifically, the company will install a GM Performance LS3 V8. Though Bruiser Conversions doesn't yet list exactly what specifications the engine has, it offers the LS3 in both 450- and 500-horsepower versions on the previous Wrangler JK generation. The new V8 will be fitted to the factory 8-speed automatic transmission, and the company says that the transmission will function exactly as it does with the original V6 or turbo inline-4. In addition, Bruiser Conversions says all factory gauges, cruise control, hill descent control and other electronic aids will work like they did from the factory. Pricing is currently not listed for the conversion, but the company is taking pre-orders for both in-shop installations and do-it-yourself kits. Going off the conversion costs for an older JK Wrangler, it will probably cost between $20,000 and $30,000 to have Bruiser Conversions do the installation. In the case of the JK kits, they're about $5,000 less than having Bruiser Conversions do the work. We've reached out to the company to see if we can get specific pricing and will update the post if and when we hear back. Related Video: This content is hosted by a third party.

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.
