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).

Here's another look at the next-gen Jeep Wrangler Unlimited

Yesterday, we got a sneak peek at the next generation Jeep Wrangler Unlimited. As you might expect, it looks a lot like the current Wrangler. Really, did you expect anything different? The big news is that the leaked images show that the doors and top are removable, something that was unclear until now. Thanks to our friends at JL Wrangler Forums, we have some pretty new renderings based on those same leaked images. While these aren't official, this should be pretty damn close to what the final production model will look like. While it may be all new, the design is just a revolution of the tried and true formula. Fans might burn down the factory if designers strayed too far. The entire body has been worked over, with changes to the grille, bumper, fenders, and lights. The square tail lights look a lot like those on the Renegade. We keep seeing more and more leaks and spy photos, so an official reveal can't be too far off. In addition to the four-door Wrangler Unlimited, look for the long awaited Wrangler pickup truck.

2018 Jeep Grand Cherokee Trackhawk Drivers' Notes | Haulin' the groceries

Powered by the same supercharged Hemi at the heart of Dodge's Hellcat cars, the 2018 Jeep Grand Cherokee Trackhawk is the sort of vehicle that comes from a " Why not?" attitude from the maniacs at SRT. It's not for the faint of heart, nor for the cash-strapped. With 707 horsepower and 645 pound-feet of torque, it's capable of a 0-60 sprint of just 3.5 seconds. Its base price, however, is $86,995, though our tester's sticker totaled just a few bucks shy of $100,000. Senior Editor, Green, John Beltz Snyder: "What business does a Jeep have going 0-60 in 3.5 seconds?" This was my thought as I merged into rainy rush-hour traffic on Woodward Avenue in the 2018 Jeep Grand Cherokee Trackhawk. "Why does an SUV need to have 'Track' in the name?" I thought as I unintentionally broke the tires loose pulling away from a stoplight. I hit the "Eco" button, but the Jeep still roared with every toe-tap, and still managed to gulp down nearly a quarter of a tank of gas on my ride home. That sound, though, is amazing, and surely more unsettling to other drivers coming from such a big beast of a ute. Anyway, this Jeep feels more grown-up than other Hemi-powered vehicles I've driven. The fit and finish in this $99,000 Jeep is far nicer than, say, the Dodge Durango SRT (though at a much higher cost). If another driver didn't pay close attention to the badging, they might see this and think it just another Jeep. The sound, though, will give it away every time. Associate Editor Joel Stocksdale: If Fiat-Chrysler knows how to do anything, it's making fast SUVs, and the Grand Cherokee Trackhawk is further proof of that. And by that I mean, they know how to make them fast, and they know how to make them pleasant to drive. The Trackhawk definitely handles the fast part better than its SRT Durango and SRT Grand Cherokee cousins, what with its extra 230-odd horsepower. This big beast seriously rockets when you punch the throttle. The nose rises up, the supercharger screams, the exhaust rumbles and the speedometer ticks up much faster than you'd ever think. And it feels strong at all revs. Also impressive is that you don't have to really think when flooring it. The all-wheel-drive and fat tires offer so much grip the Jeep simply goes. The pleasant to drive part comes in the fact that the Trackhawk is very comfortable. The suspension has plenty of give, providing a good ride over pockmarked Motown roads.
