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).

Hellcat motor 'fits like a glove' in the Wrangler and Gladiator, says Jeep

Just like "technically correct" is the best kind of correct, "technically possible" is the best kind of possible. Specifically, it's technically possible to slot a Hellcat crate motor into the Jeep Wrangler and Gladiator, as confirmed by Jeep brand chief Tim Kuniskis. Speaking to Australian media last week, Kuniskis went on to say that "everybody" keeps asking him if the supercharged, 6.2-liter Hellcat V8 fits in the Wrangler and Gladiator, and that the answer is yes. "It fits like a glove," said Kuniskis. But — there is a but — the fitment is so close for comfort, it makes the combination one that Jeep can never produce. "There's no air space around the engine [...] so you have no crush space, you have nothing that can be used to absorb energy in a crash. It's not a problem to put it in — other than emissions and fuel economy — except it would never pass any crash tests, and that's a problem," as Kuniskis told Drive. However, since the Hellcat is now out of the bag, it's probably only a matter of time until hobbyists with access to these engines will start putting them into Wranglers and Gladiators. And with the time-honored piece of advice — just don't crash into anything — it'd be a combination worth seeing and hearing. Just to throw it out there, a "Hellcrate" engine costs less than $20,000 new. Kuniskis also said that Jeep is "gauging interest" for the J6 concept, one of the Easter Jeep Safari concepts that were just revealed. "[The J6] is just a concept at this stage. But that doesn't mean we're not going to gauge interest for it." However, he said justifying its production is apparently "tough."

Jeep Grand Cherokee redesign delayed

The launch of the next-gen Jeep Grand Cherokee is being now being pushed back until late 2018 or even into 2019, Jeep CEO Mike Manley indicated Friday, according to Automotive News citing a Reuters report. Under the original five-year plan, the SUV was supposed to be replaced in the third quarter of 2017. That would have made for a big year for Jeep with a refreshed Renegade and new Wrangler also slated for 2017. A delayed Grand Cherokee could send ripples through Jeep's product plans. The three-row Grand Wagoneer is meant to give the brand a vehicle to take on the Land Rover Range Rover, but it's supposed to use the same platform as the Grand Cherokee. This change is rumored to push that important model's launch further back. There's less uncertainty when it comes to the next-gen Wrangler. Manley said that the model was "broadly on track," according to Automotive News. The five-year plan aimed for a launch in the second quarter of 2017. Controversy, however, has swirled over possible plans to move the Wrangler from its longtime Toledo, OH, factory. One problem Jeep doesn't have to worry about right now is sales. According to Automotive News, Manley said volume was up 20 percent globally and could reach 1.2 million by the end of the year. He also indicated the brand was "on pace" to reach its 1.9-million-vehicle goal for 2018. The Grand Cherokee delay comes in the wake of rumors that FCA US is shuffling around its previous five-year vehicle launch plan to postpone several models. Related Video:
