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).

Jeep Cherokee recalled to add power liftgate moisture shield

The Basics: Jeep is recalling 55,687 examples of the 2015-2016 Cherokee that have the optional power liftgate and have production dates between February 18, 2015, and September 10, 2015. These include 32,784 vehicles in the US, 10,138 in Canada, 924 in Mexico, and 11,841 outside the NAFTA region. The Problem: Water can potentially leak onto the power liftgate control module and cause a short circuit. This is a potential fire hazard. Injuries/Deaths: Jeep has no reports of injuries or accidents The Fix: Dealers will inspect the area for damage and will replace parts as necessary. They will also install an improved moisture shield that will offer better protection. If You Own One: Owners should try to keep the cargo area of these vehicles dry until dealers perform the recall. More Information: Jeep also issued a recall for this issue for 164,003 total examples of the 2014-2015 Cherokee in June. RECALL Subject : Liftgate Module Short due to Water Leak Report Receipt Date: DEC 09, 2015 NHTSA Campaign Number: 15V826000 Component(s): ELECTRICAL SYSTEM , STRUCTURE Potential Number of Units Affected: 32,784 All Products Associated with this Recall Vehicle Make Model Model Year(s) JEEP CHEROKEE 2015-2016 Details Manufacturer: Chrysler (FCA US LLC) SUMMARY: Chrysler (FCA US LLC) is recalling certain model year 2015-2016 Jeep Cherokee vehicles manufactured February 18, 2015, to September 10, 2015 and equipped with the power liftgate option. In the affected vehicles, water mater leak into the Power Liftgate Control Module and result in a high resistance short circuit. CONSEQUENCE: A short circuit in the module increases the risk of a fire. REMEDY: Chrysler will notify owners, and dealers will inspect the module and connectors for corrosion, replacing the damaged components as necessary. The mastic shield will be removed and the module will be covered with a water shield. These repairs will be performed free of charge. The manufacturer has not yet provided a notification schedule. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler's number for this recall is R67. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. Statement: Moisture Shield Upgrade December 18, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 32,784 SUVs in the U.S.

Jeep Cherokee faces on-sale delay

A report in The Wall Street Journal looks at some of the obstacles to the 2014 Jeep Cherokee that go beyond its mootable yet "very contemporary" looks, almost all of them based on Fiat's financial position. Starting with that sheetmetal, in defense of it SRT president Ralph Gilles and Jeep design head Mark Allen said they wanted to "make sure the design still looks modern five years from now."
The WSJ piece doesn't cite longevity as a factor, instead saying that its features originated in a design for an Alfa Romeo, the transformation into a Jeep design meant allowing Chrysler get it to market more quickly and save "hundreds of millions of dollars" in engineering.
The need for Fiat to save money while it weathers the European situation has cut budgets for development, engineering and the pace of retooling the Toledo, Ohio plant to build the Cherokee. In a familiar case of snowballing at work, among the effects will be pushing back the Cherokee's volume sales date and delaying updates to some of Chrysler's other products.
