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).

Why the 2018 Jeep Grand Cherokee Trackhawk really exists

"But really, what do we do for Jeep? We listen to our customers, that's our job. We give them what they want. So the reason why is, they ask. Lots of them asked." – Darryl Smith "Why not?" It's a simple-enough explanation and one that should resonate with any car lover who views the absurd and the gloriously pointless as fundamental principles of their passion. And putting a ridiculously powerful engine into a vehicle that would normally not have one is perhaps the pinnacle of that. It's the reason that so many of us view a Mercedes-AMG E63 wagon as far cooler than an SLS AMG with roughly the same engine. With that in mind that we sat down with two of the men responsible for the 2018 Jeep Grand Cherokee Trackhawk, the latest entry into the absurd and gloriously pointless segment. We wanted to find out from Darryl Smith, director for SRT engineering, and Paul Mackiewicz, vehicle development manager, if there were actual market-based reasons for the Trackhawk's creation. Effectively, why'd they actually do it? "Why not?" Smith immediately offered during an interview at the New York Auto Show, clearly possessing a similar mindset. "But really, what do we do for Jeep? We listen to our customers, that's our job. We give them what they want. So the reason why is, they ask. Lots of them asked." View 24 Photos If "lots" of people are asking for a 707-horsepower, 645-pound-feet, off-road-capable, luxury-lined, five-person SUV, then perhaps we shouldn't be too worried about the demise of the human-driven automobile after all. "There is a very defined customer base out there that want a sport SUV," Mackiewicz said. "They want a sports car with the capabilities of having an SUV, of being able to tow, of being able to drive their sports car all year round. And that's what this car enables. It is ultimate performance, all year round, in any condition." If BMW, Mercedes-Benz, Porsche, and even Maserati can produce high-performance SUVs, doesn't it seem fitting that the father of all SUV brands should top them all under the hood? Of course, expanding the 6.2-liter Hellcat engine beyond the Challenger and Charger is clearly a smart business case in the current SUV-obsessed marketplace. FCA had a lust-worthy engine, and it had a solid performance base in the existing Grand Cherokee SRT, so it can be argued that marrying the two made sense and that it could be done with minimal fuss — even if in practical terms, it's absurd.

2018 Jeep Grand Cherokee vs. midsize crossovers and SUVs: How they compare on paper

In a world full of SUVs and crossovers all competing for similar buyers in similar segments, there are still some models that find their own little niches that lack such fevered fighting. The Jeep Grand Cherokee is one of those vehicles. It's an oddball in the sense that it's a midsize crossover SUV with a unibody chassis and independent suspension, but it still uses rear-wheel-drive and four-wheel-drive systems and has some off-road capability. It's also a midsize crossover, but only offers two rows of seats. Despite the Grand Cherokee's odd nature, we did come up with a few crossovers and a classic SUV that seem to match the Jeep in size and pricing. We looked at the numbers to compare them on paper. You can find the raw data in the chart below and deeper analysis after that. As always, this is just a comparison of specifications and you'll want to check out our driving impressions of each car if you're getting serious about one or all of these vehicles. And if you want to compare any of these against other vehicles, be sure to check out our comparison tool. Engines and Drivetrains When comparing base engines, the Jeep Grand Cherokee's 295-horsepower is the clear power winner, beating the next most powerful 4Runner by 25. But in torque, the 4Runner takes the laurels with 278 pound-feet, narrowly edging out the Edge's (no pun intended) turbocharged 2.0-liter four-cylinder's 275. That four-cylinder in the Edge will also be picking up another 5 horsepower for 2019, but it still won't win this power contest. Both Ford and Jeep also have another advantage in the fact that you don't have to settle for the base powertrain. Ford has two other engine options, a naturally aspirated V6 and a twin-turbocharged V6, the latter of which outguns the Grand Cherokee's gasoline V6 in both power and torque. That engine will also be bumped up to an impressive 335 horsepower and 385 pound-feet of torque. View 20 Photos The Jeep has the most engine options, though, and it's the only to offer V8 and diesel options. On most Grand Cherokees, the options include a 5.7-liter V8, which is only available with 4WD. It makes 360 horsepower and 390 pound-feet of torque, outperforming even the 2019 Edge's twin-turbo V6. The diesel engine doesn't make much power with just 240, but it makes up for it with torque at 420 pound-feet. And of course there are the SRT and SRT Trackhawk models with even bigger and supercharged V8 engines respectively.
