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).

FCA plotting larger Jeep Renegade, Fiat 500XL

The joint development of the new Jeep Renegade and Fiat 500X goes to show what the combined efforts of the Fiat Chrysler Automobiles group can yield. But don't expect the Italian-American automaker to stop there. According to Autocar, the company is planning to base another pair of larger SUVs on the same platform. The Jeep version would take the place of the previous Compass and Patriot, slotting in between the Renegade and Cherokee. Meanwhile, the Fiat version would further bolster the Cinquecento lineup to sit alongside the 500 hatchback, 500L minivan and 500X crossover. Details remain few and far between at the moment, but they wouldn't be the extent of the growth plans for either brand. Jeep is reportedly zeroing in on a decision on the long-rumored sub-Renegade model, while also preparing to expand up-market with the return of the Grand Wagoneer. Fiat is reportedly abandoning the prospect of offering a full model line as it once did. While the 500 range will continue to form a vital part of the brand's business, it's also tipped to be going after the no-frills, bare-bones market dominated by Renault's Dacia brand. To that end, it would seek to build upon the Panda by offering a larger, but still low-cost hatchback to rival the Ford Focus and VW Golf, and succeed the discontinued Fiat Bravo, but based on the 500L's platform and built in Turkey to keep costs down. This second pillar of the Fiat brand wouldn't likely be offered in the US, however, where we'd expect the 500 line to continue representing the Italian automaker. Related Video:
