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 recalling 75,000 Cherokees over air-conditioning lines

Fiat Chrysler Automobiles has issued a recall for an estimated 75,364 examples of the Jeep Cherokee in the United States. The problem stems from an air-conditioning line, which may have been installed to close to the exhaust manifold. "Under certain operating conditions," says FCA in the statement below, "this may pose a fire risk." Thus far, however, the company says it is "unaware of any related injuries or accidents." The owners of those 75k Jeeps (as well as another 18,000+ in other markets) can expect to hear from their local dealers to have the problem rectified. However the manufacturer also advises owners to watch out for indicators like air-conditioning loss or a dashboard warning light and contact their dealers if necessary.

FCA US launched an investigation after the National Highway Traffic Safety Administration received two customer complaints involving smoke and fire. The Company discovered air-conditioning lines on some vehicles may have been installed in close proximity to their engines' exhaust manifolds; under certain operating conditions, this may pose a fire risk. FCA US is unaware of any related injuries or accidents. The recall is limited to certain 2015 Jeep Cherokees. Additional vehicles are affected in other markets. They include an estimated 7,571 in Canada; 4,018 in Mexico; and 6,942 outside the outside the NAFTA region. Affected customers will be advised when they may schedule service, which FCA US will provide free of charge. . Customers who observe air-conditioning loss or any other concern, such as a dashboard warning light, should contact their dealers. Customers with additional questions may call the FCA US Customer Information Center at 1-800-853-1403.
