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's Jefferson North plant builds 5-millionth SUV [w/video]

Chrysler's Jefferson North Assembly Plant opened in 1992 for production of the first Jeep Grand Cherokee, but in the subsequent years, the Detroit plant has gone on to produce some of the company's biggest SUVs including the Jeep Commander and Dodge Durango. Earlier this week, the plant produced its five-millionth SUV, which, fittingly, was a Grand Cherokee.
Celebrating the plant's five-millionth unit, the silver 2014 Grand Cherokee was promptly donated to the USO. In addition to this milestone SUV, Chrysler also had a near-perfect 1993-95 ZJ Grand Cherokee on hand for the photo op. Scroll down for the Chrysler press release as well as a video showing some of the speeches from the celebration.

NHTSA investigates FCA for SUVs that roll out of Park

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2014 Dodge Durango and 2014-205 Jeep Grand Cherokee after 14 complaints of the SUVs rolling out of Park. An estimated 408,000 of them could be affected, if a recall is necessary. All of the current complaints submitted to NHTSA about the issue concern the Grand Cherokee, and the claims allege that the SUV can roll out of Park whether or not the engine is running. Some folks report that they check the indicator each time because the gear sometimes fails to engage. Among the 14 cases, there are five accounts of crashes and three injuries, including a situation with someone allegedly being rolled over. NHTSA's preliminary evaluations are meant to investigate "the scope, frequency, and safety-related consequence" of a reported problem. They don't necessarily lead to a recall.

The unintended motion has occurred with both the engine off and the engine running. ODI has also identified EWR field report data related to the alleged defect. The model year 2014 and 2015 Jeep Grand Cherokee vehicles are equipped with an electronic gear selector (shift-by-wire system). The gear selection is made by pressing the shifter-paddle forward or backwards; the shifter does not move along a gate path as with conventional gear selectors. A Preliminary Evaluation has been opened to asses the scope, frequency, and safety-related consequence of the alleged defect. The VOQs associated with the opening of this investigation are: 10733158, 10730952, 10683556, 10679497, 10583366, 10725429, 10715401, 10711893, 10676998, 10668651, 10662619, 10662308, 10605865, and 10567538.
