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).

Dream Cruising in three Jeep concept cars

Those of you that have attended the yearly Woodward Dream Cruise, know that the rolling car show is many things to many people. A chance to pull the Corvette out of the garage; a time to ogle rare models you've never yet seen in the metal; a weekend for drinking a cold one with friends and simply taking in the festivities. But for our roving editor Brandon Turkus, this year was a chance to cruise in some concept Jeeps that most people will never see, let alone drive. As Turkus aptly points out from the start, Woodward isn't exactly Moab. But wheeling the off-roaders is nevertheless an eye-opening experience; they may not be upcoming products, but these Jeeps tease out a lot we'd like to see from the brand in the future. You can find these mini Short Cut reviews above, and below, but here's a recap of what Turkus got to drive. Jeep Wrangler Staff Car Concept This one's a proper salute to the Jeep military service vehicles of yore. It's an open-air concept based on the four-door Wrangler, with tons of heritage design cues. It looks old, but we promise, it's totally new. It's got basic steel wheels, a stretched canvas roof, bench seats, a painted steel floor, a built-in cooler that accommodates up to 85 cans, and is painted in an iconic Sandstorm color. When the going gets tough, the Staff Car can handle it with aplomb, thanks to the Jeep Performance Parts two-inch lift kit, Fox shocks, Dana 44 axles, and the Wrangler's 3.6-liter V6. Jeep Chief Concept This Wrangler-based concept is an excellent tribute to the classic, fullsize Jeep Cherokee from the 1970s. It's painted in a vintage Ocean Blue color, with a white, "French Bread" roof. There's also a custom razor grille (something made famous on the original Wagoneer), removable sides, chrome bumpers, and classic-looking, 17-inch wheels. Inside, there's surfer-inspired pink, blue, and white cloth mixed with leather trim, with more fun details like a Rosewood front passenger grab handle and tiki-look shift handle. Of course, this thing looks to be truly capable off-road, too, with a two-inch lift kit, Fox shocks, Dana 44 axles at the front and rear, and a 3.6-liter Pentastar V6 underhood. Jeep Wrangler Africa A take on the Wrangler Unlimited, painted in Desert Tan, and powered by a 2.8-liter diesel engine. It looks killer, with 17-inch, body-colored steel wheels wrapped in 35-inch BF Goodrich Mud Terrain tires. There's a two-inch lift kit, Dana 44 axles, and Fox shocks.

Jeep Wrangler Polar is a tasty frozen treat

Perhaps it's because we've seen so many kitted-out examples over the years, but it seems to us that the Jeep Wrangler tends to wear its special-edition duds better than most models. It might be the icon's familiar rectilinear proportions or the inherent bolt-on look of its extremities - bumpers, mirrors, lighting, and step rails - but we've seen precious few factory specials that look anything but excellent.
Case in point: this new Jeep Wrangler Polar unveiled at the Frankfurt Motor Show. This European-market limited-edition model is said to be a celebration of winter driving, which evidently works out to a body-color hardtop, black-accent seven-slot grille, 18-inch gloss black wheels, Trac-Lok limited-slip differential and a hard hat for the spare tire. Finished here in Hydro Blue (Billet Silver Metallic and Bright White are also available) and a black interior with Polar White accents, the Polar edition features badges displaying 78° S and 106° E longitude and latitude coordinates for Vostok, Antarctica.
This new Jeep will be available in both standard and Unlimited formats with either the 3.6-liter Pentastar gas engine or the still-not-for-US 2.8-liter turbodiesel when it bows early next year. For further details, check out our gallery above and the press release below.
