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).

Inexperienced Jeep driver buries his Wrangler at sea

There's an old maxim in off-roading that states, "Four-wheel drive doesn't keep you from getting stuck, it just gets you stuck in worse places." The truth of this statement was perfectly illustrated recently in a YouTube video of a Jeep Wrangler digging its own grave at the beach. On May 11, a YouTuber named Dan M uploaded a video he titled, "Drunk guy doesn't know how to off-road and ruins nice Jeep." The video, shot at dusk on a rocky looking beach, shows a blue Wrangler driving out into the surf without a care in the world. Dan, providing commentary along with an unseen female companion, was impressed with the Jeep driver's dash at first. "Wow, he must do that a lot because he ain't scared of getting stuck or anything," said Dan. As the Wrangler got deeper into the water, the Dan's friend expressed her doubts that the Jeep driver would make it out, especially when the Jeep got snagged on a little spit of sand sticking out into the water. Dan wasn't worried, however. "No, he'll manage to get out of there, he'll make it out of there. He'll back out and get out," he said. Dan's confidence in the Jeep driver was sadly misplaced, unfortunately. The driver managed to get the Jeep stuck on the sand bar then made the rookiest of rookie mistakes–he just gunned it. "Oh man, he's done! He's done!" yelled Dan as the Jeep driver proceeded to dig a huge hole in the sand that sunk the Wrangler up to its frame just as the tide started coming in. With that kind of dunking, especially in salt water, that Wrangler was probably a total loss, much like the Grand Cherokee that got washed downriver last week somewhere in Europe.

NHTSA closes investigation on 4.7M FCA power modules, no recall

FCA US hasn't had the best time with recalls as of late. Not only did the company recently agree to greater safety oversight and paid $105 million to the government, that came just days after hacking fears prompted a 1.4-million model recall campaign. However, a recent decision to close an investigation by the National Highway Traffic Safety Administration means that the automaker doesn't have to worry about another major recall possibly affecting 4.7 million vehicles, according to the agency's report (as a PDF). Last September, the Center for Auto Safety petitioned NHTSA to investigate an alleged problem with the totally integrated power module (TIPM) on these FCA US models. The group claimed that a fault with the component could cause a variety of maladies, including stalls, not starting, catching fire, unintended acceleration, and airbag non-deployment. At the time, it also submitted 70 cases where this had reportedly happened. According to NHTSA, "no valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration, or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components." The agency did find signs of an issue with the fuel pump relay in some Jeep Grand Cherokees and Dodge Durangos, but FCA US issued recalls for the problem in September 2014 and February 2015. Without anything else to go on, the Feds don't think it's worth investigating this topic any more.
