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).

2014 Jeep Grand Cherokee EcoDiesel

Choose Your Own Adventure... But Choose Wisely
Jeep has got you covered. We can say this without even having to know what it is you want, because there's hardly an option or configuration that you won't find in the 2014 Grand Cherokee. There are three different engines, three different four-wheel-drive systems (plus rear-wheel drive), four different trim levels - not counting SRT - two different suspension setups and five different settings for various off-road terrain conditions. If you happen to check the box for Quadra-Lift, you'll also have five different ride-height settings for the driver-selectable air suspension.
As you might expect with so many customization possibilities, the way a buyer checks the options sheet can have a profound effect on the final product and its capabilities, to say nothing of its price. Nowhere is that more true than with the Grand Cherokee's choice of engines, with the brand-new 3.0-liter EcoDiesel V6 stealing the spotlight from the still excellent gasoline-fueled 3.6-liter Pentastar V6 and 5.7-liter Hemi V8 powerplants that carry over from last year. No matter which engine you choose, though, it will be paired up with Jeep's new standard eight-speed automatic transmission from ZF. This, ladies and gentlemen, is very good news indeed.

Updated 2014 Jeep Grand Cherokee ace same controversial moose test it failed in 2012 [w/video]

Some background: one of the more scandalous international incidents of he-said/he-said from 2012 was when Swedish magazine Teknikens Varld put the Jeep Grand Cherokee through its "moose (or elk) test" and reported that the SUV nearly rolled over. That lead to a whole lot of accusations and rebuttals: more than one website and Chrysler's own blog reported that the Jeep was overloaded; Chrysler said Teknikens printed the magazine then let Chrysler respond, Teknikens answered all of the charges in a lengthy post and said Chrysler was given a chance to comment before it went to print; when Chrysler sent investigators to oversee the test and the Jeep didn't go up on two wheels as it did in the first test, furthermore all four wheels stayed on the ground when Auto Motor und Sport tested a Grand Cherokee in the same way.
Teknikens then re-ran the test with a new vehicle and said it's been doing this test since the 1970s, uses the loading information that Chrysler provides to the Swedish motor authority and the previous Grand Cherokee passed with no problem. In the second test, the Jeep failed again, then it gave Chrysler engineers access to the car's electronics and ran the test again. In that second round the Grand Cherokee didn't repeat the lurid two-wheel action, but in eleven runs it blew out front left tire seven times. Chrysler still objects to the results of all of those tests and maintains that vehicle was safe.
The 2014 Grand Cherokee was given its shot at the gauntlet in the latest round of moose tests, and Teknikens Varld reports that it passed without any problem at all, its stability control working perfectly, controlling motion at low speeds and all the way up to 44.1 miles per hour.
