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:

FCA recalls 210,000 new Jeeps and Dodges due to a brake issue

FCA is recalling some 210,000 vehicles in the U.S. and elsewhere over a possible braking issue. On this occasion, the recall is made less complicated by the fact that about one-third of the affected vehicles are so new, they still reside on dealer lots, making them easy to tally up and put right. The recall concerns 2018 Dodge Journeys, 2019 Jeep Cherokees and 2018-2019 Dodge Grand Caravans and 2018-2019 Jeep Compasses. Most were built in spring 2018, and the recall is related to a brake system component that failed to meet FCA specifications. Further information available on the NHTSA website details the issue, saying that insufficiently coated rear brake caliper pistons may cause gas pockets to form in the brake fluid of very new vehicles. This in turn can reduce rear brake performance — bubbles in brake lines are not desirable. FCA underlines that the brakes still function, but stopping distance can be affected. As a remedy, the brake systems are inspected and re-bled. The recall is slated to begin on Sept. 28. In addition to 154,337 vehicles in the United States, the recall concerns 19,066 units in Canada, some 900 in Mexico and some 35,500 vehicles on other markets.

Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).
