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 Red Rock concept brings Moab to SEMA

Among the concepts that FCA is showcasing at SEMA this year, the Jeep Wrangler Red Rock concept has been decked out with accessories from both the Mopar and Jeep catalogs. The concept is based on the existing Wrangler Unlimited Rubicon Hard Rock edition, but has been taken even further in for this show truck. It pays tribute to the Red Rock 4-Wheelers club and the Easter Jeep Safari it hosts every year in Moab, UT. The Red Rock concept rides on a 2-inch lift kit with 17-inch beadlock wheels shod with 35-inch all-terrain tires. It also has differential covers, a reinforced swing gate and wheel mount, a power winch, LED headlamps and fog lights, and an onboard CB radio. To help it crawl those rocks, it boasts electronic locking differentials, a Rock-Trac transfer case, and Dana 44 solid axles front and rear. Visually setting this concept apart are such special touches as a power-dome hood, red tow hooks front and rear, new rock rails, a color-keyed grille with low-gloss inserts, low-gloss bumpers, and of course the requisite special badging. Inside it's been done up in brown leather with silver accents and a special grab-handle plaque. This particular version will remain a showpiece only. So if you want to see it, you'll have to head to the show floor in Vegas this week. However Jeep is committed to undertaking a production run of 50 examples with many of the same special touches to celebrate the 50th anniversary of the Easter Jeep Safari next year.
