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).

Chrysler recalling 644k more Dodge Durango and Jeep Grand Cherokee SUVs over brakes

Early last month, we reported on Chrysler issuing a preemptive, proactive recall for about 25,000 units of the Jeep Grand Cherokee and Dodge Durango. The issue revolved around a brake system that wasn't causing any actual problems, but delivered an unsatisfactory brake feel, so Auburn Hills called in a good 25,000 of SUVs around the world, including 18,700 in the United States.
Now Chrysler, having apparently determined that the brake problem on its sport utes is actually much bigger than it initially realized, has drastically broadened the scope of the recall. As a result, the National Highway Traffic Safety Administration has issued a recall for precisely 655,354 examples of the Grand Cherokee and Durango, covering the 2011 through 2014 model years. In addition, Chrysler is recalling 42,380 units in Canada, 21,376 in Mexico and 159,685 overseas.
The problem which Chrysler found revolves around the brake booster, whose center shell has been found to be subject to corrosion, allowing water to get into the brake system. That water in turn could freeze, preventing the brakes from working as well as expected.

Jeep driver nearly gets washed away by fast moving river

Just because you can do something doesn't mean that you should. For example, you should never attempt to cross a fast-moving river in a bone stock Grand Cherokee no matter how shallow the river looks. Especially if you don't know what you're doing. A video posted recently to the Facebook group Jeep EXPERIENCE, shows an inexperienced jeep driver learning that lesson the hard way. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. The video starts innocently enough, with a group of off-roaders watching one of their friends attempt to ford a shallow looking river. Things quickly go sideways however, when the driver of the silver Grand Cherokee just plunges right in and quickly gets in over his head. The river is moving faster than the driver thinks it is, the driver panics, makes some bad decisions, then the jeep is turned over and swept downstream. Eventually, the jeep is hauled out by a Land Rover after a long comedy of errors that involves one guy losing his trousers to the current and the Cherokee ingesting untold gallons of water. What went wrong here? Well, It's pretty obvious from the video that the Cherokee driver didn't have a clear idea of where he was going or about the condition of the riverbed. He chickened out halfway across the river, and in what appears to be a misguided attempt at turning back, he reverses, digs himself deeper in the riverbed, then turned broadside on into the current. When he changes his mind again and decides to just gun it for the opposite shore, he drives directly into a deep water hazard that would have been obvious to an experienced off-roader. At that point the jeep and the driver were doomed. Hopefully the driver learned a lesson here, and hopefully he didn't pollute that river too much with the jeep's fluids.
