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).

Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

2014 Jeep Cherokee: Long-term wrap-up [w/video]

Sorry, Sweet Brown. Your place in Autoblog history as the most highly demanded long-term car has come to an end. We just finished a one-year test of a 2014 Jeep Cherokee Trailhawk, and after 27,000 miles of hard use, one thing is very clear: this is one of the best all-rounders we've ever tested. The Jeep Cherokee isn't perfect, and our long-term tester proved that. But no compact crossover is. Still, the Trailhawk oozed personality where other small CUVs seem bland, and the Jeep felt more like a trusty companion than just another test car. For road trips, the requests weren't, "Can I have a long-term car this weekend?" They were specific: "I'd like the Cherokee, please." No matter the season, the driver, or the situation, the Jeep was always a sure fit. Fiat Chrysler bet big with this one. It had a global platform, a new engine, and one heck of a funny face. The end result was a CUV that we'd gladly welcome back into our fleet any day.

Lots To Like Admittedly, we picked the Trailhawk trim for cosmetic reasons (more on it's off-road capability in a second). To this day, many of us still think the Cherokee is a homely little thing, but its inherent weirdness doesn't stand out as much when you add the black accents and big, knobby tires of the Trailhawk model. The butched-up look really works here, and we wouldn't have wanted the Jeep any other way. Of course, opting for Trailhawk package meant getting one of Jeep's more expensive Cherokees. Our car carried a sticker price of $38,059, but that's without goodies like HID headlamps (which we could have used – the halogens were pretty weak), a sunroof, or even full leather seats. This car genuinely felt premium, though. Right off the bat, the Cherokee received compliments for its comfortable, supportive seats, not to mention the high quality of interior materials and the general fit and finish. Specifically, the interior packaging won us over early on. We appreciated things like the higher-end stereo, smart layout of the center console, and ample storage, including a bin under the front passenger seat cushion. (That said, we also found that this bin becomes a catch-all for wrappers, french fries, and anything else that might get dropped on the seat.) The Uconnect infotainment system was a joy to use, never giving us any finicky problems or usability issues.
