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).

NHTSA investigating why Jeep recall fix is taking so long

Jeep's saga with the National Traffic Safety Administration and the voluntary campaign to repair 1.56 million vehicles for allegedly unsafe trailer hitches, is getting yet another chapter. The controversy appeared to finally be over in January when the automaker found a supplier for the replacement parts. Nothing is ever that easy, though, and the government regulator is now requesting documents from the company to clarify why the repairs are taking so long to begin.
Jeep parent company Chrysler has until July 16 to submit documents and answers to NHTSA explaining the situation. The regulator claims that despite its compromise to inspect and repair the models with improper hitches in June 2013, Chrysler didn't find a part supplier until December and didn't order the replacements until January. The government agency believes that the first components weren't manufactured until May of this year and vehicles may not actually be repaired until as late as August. According to the report, if the Chrysler doesn't supply what NHTSA is asking for, the agency could "take additional appropriate action as warranted."
Throughout this entire process, Chrysler has asserted that the vehicles met the applicable crash test standards of the time, and it has kept NHTSA abreast of the repair activity. In a recently released statement it said that the regulator analyzed eight rear impact reconstruction tests and found the replacement hitch to be safe. To keep up with the high demand for replacements, Chrysler is working with multiple suppliers, and they are running three shifts, six days a week to get the parts ready as soon as possible.
