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 resolves recall issue with NHTSA, will inspect, upgrade affected Jeeps

Chrysler made big news earlier in the month by refusing a recall request from the National Highway Traffic Safety Administration for the 1993-2004 Jeep Grand Cherokee and 2002-2007 Jeep Liberty. Last week, NHTSA boss David Strickland countered by defending his agency's request for the recall of 2.7 million Jeep SUVs. Today marked the deadline for Chrysler to formally respond to NHTSA, and it seems that both parties have met in the middle with Chrysler inspecting and upgrading some of the affected vehicles without using the word "recall," which would constitute the admission of a defect; instead, Chrysler said that it is conducting a "voluntary campaign."
At issue on these vehicles is the positioning of the fuel tank behind the rear axle that could get damaged during a rear-end collision. NHTSA has stated that at least 51 people have been killed in rear-end collisions involving these Jeeps after the vehicles caught fire, to which Chrysler countered by pointing out that both models "met and exceeded" the requirements for fuel-system integrity.
As a compromise on the situation, Chrysler says that it will inspect all pre-2004 Grand Cherokees and pre-2007 Liberty models and, "if necessary, provide an upgrade to the rear structure of the vehicle." According to Automotive News, this upgrade will consist of adding a trailer hitch that will presumably better protect the rear-mounted gas tank. Vehicles already equipped with a factory or Mopar hitch will not be modified. Chrysler's official statement on the matter is posted below, but no additional information has been released, such as when the campaign will begin and how many vehicles could be affected.

FCA recalling 63k Jeeps, Vipers and Ram ProMaster City vans

Fiat Chrysler Automobiles has announced a pair of recalls cover nearly 63,000 vehicles. The bigger of the two actions covers manual-transmission-equipped vehicles from 2006, including the Jeep Liberty and Wrangler, as well as the Dodge Viper. FCA engineers uncovered that the clutch ignition interlock switches use a kind of wire that was part of a previous recall campaign. Because of this, the company said that affected vehicles may not start, although in rare cases, "if recommended starting procedures are not followed," the affected vehicles may lurch forward after turning the key. Those recommended starting procedures "include activating the parking brake, placing the shift lever in neutral and pressing the clutch pedal before turning the vehicle's ignition key." Recall number two affects the company's 2015 Ram ProMaster City cargo and passenger vans. Owners will need to report to dealers to have a piece of tape removed from the side-curtain airbags. The tape is added during assembly and in some cases, may not have been removed. That could prevent the airbags from deploying in the event of a crash. Just under 59,000 vehicles are included in the first recall, including 43,874 in the United States, 11,309 outside of North America, 2,944 in Canada and 706 in Mexico. The ProMaster City recall includes just over 3,900 vehicles. FCA claims it's unaware of any injuries, fatalities or accidents related to either recall and will perform repairs free of charge. Scroll down for the official press release on both campaigns.

The Company will replace their clutch ignition interlock switches at no charge to customers. The action follows an investigation by FCA US engineers that discovered these vehicles are equipped with switches that contain a certain type of wire implicated in a previous campaign. The wire, which was temporarily substituted by a supplier for the specified material, may break. As a result, the vehicles may not start, and in rare cases – if recommended starting procedures are not followed – a vehicle may exhibit unintended movement when its ignition key is turned. FCA US is unaware of aware of any related injuries or accidents involving this population of vehicles.
