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 taking big risk snubbing NHTSA

Maker Insists Feds Overstate Risk Of Fires With Grand Cherokee, Liberty Models
It's not often that recall stories make it above the fold, in that old newspaper parlance, but when one shows up as the lead story on the network evening news programs, you know it's something big.
And so it is with Chrysler snubbing its nose at a request by the National Highway Traffic Safety Administration to recall 2.7 million Jeeps the feds insist are at risk of potentially catastrophic fuel tank fires in a rear-end collision.

Jeep follows up Super Bowl spot with call to help the USO

Once again, Chrysler had one of the most talked about Super Bowl commercials with its two-minute Whole Again Jeep spot, which was used to highlight its Operation SAFE Return program for US military personnel returning home from active duty. As part of this campaign, Jeep announced today that it will be donating up to $300,000 to the United Services Organizations (USO), and you can help.
Simply tweet using the #joinOSR hashtag on Twitter, visit the Yahoo! homepage or go to the Jeep Operation SAFE Return website, and Jeep will donate $1 to a fund that provides returning troops things like employment assistance and incentives to buy new vehicles. Jeep is also donating to this charity to the tune of $250 for each Jeep Wrangler and Wrangler Unlimited (including the Freedom Edition model) and Jeep Patriot Freedom Edition model sold.
