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).

Jeep Wrangler Polar Edition coming to America

Jeep originally took the wraps off its Polar Edition Wrangler at the Frankfurt Motor Show in September, and at the time, we figured this would be a Europe-only affair. (Perfectly fine, since we US customers haven't exactly been lacking special edition Wrangler models over the years.) But now, and as Jeep says, just in time for winter, the automaker has announced that the ice cold Wrangler will be hitting North American showrooms in November.
Based on the Wrangler Sahara model, the Polar Edition can be had in either two- or four-door body styles, with a unique Hydro Blue paint job as the featured color. (Buyers can also opt for less-special Billet Silver and Bright White hues.) Other exterior enhancements include a body-colored hardtop, 18-inch gloss black wheels, the Powerdome (power bulge) hood, and unique decals all around the body.
But the Polar Edition isn't just about some paint and stickers. Jeep has fitted this Wrangler with a Dana 30 front axle and Dan 44 rear axle, as well as the Trac-Lok anti-spin electronic rear differential. Like all US-spec Wranglers, the Polar Edition uses Jeep's 3.6-liter Pentastar V6, producing 285 horsepower and 260 pound-feet of torque. Both a six-speed manual and five-speed automatic transmission are available.

Project Trail Force Jeep Wrangler goes to SEMA, then to a lucky winner

Extreme Terrain is an aftermarket parts company focused on the Jeep Wrangler. Partly just because it's a really cool thing to do, and probably having something to do with Jeep's upcoming 75th anniversary, Extreme Terrain found some dance partners to help work up a special 2015 Wrangler Rubicon that it will show off at the Bantam Jeep Heritage Festival in Butler, PA, then at SEMA in November, where it will be given away. Extreme worked with Barricade Off-Road and Kevin Tetz from the Spike show Trucks! to build the Wrangler it calls Project Trail Force. There is more than $24,000 worth of aftermarket gear on it, starting with the Ripp centrifugal supercharger that pumps an additional 140 horsepower into the 3.6-liter V6. It's got a 3.5-inch lift kit from Rock Krawler, Dana 44 axles strung between 37-inch BFG tires, Barricade bumpers, a 9,500-pound winch, fender flares, rock sliders, a 50-inch LED light bar above the windshield, LED spotlights on the A-pillars, and seven-inch KC Hilites headlights. Rugged Ridge worked over the inside with upgrades like all-terrain floor and cargo liners, plus seat covers, and a new navigation system with a back-up camera. If you want to win it, you can enter the contest at Extreme Terrain once every week until Oct. 23. The winner gets flown to SEMA to have Kevin Tetz hand the keys over. If you just want to see it, you can head to PA for that heritage festival. The Project Trail Force will also lead a Jeep parade that could set a Guinness World Record. The press release below has a lot more info on the build. Good luck.
