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).

FCA recalling 323,000 cars for wiring, software issues

The Basics: Fiat Chrysler Automobiles (FCA) is conducting a voluntary recall for an estimated 323,361 cars in the US. The affected vehicles were built after September 23, 2014 and include: the 2015 Chrysler 200, Ram ProMaster City, Jeep Renegade, and 2014 and 2015 Jeep Cherokees. The Problem: An insufficient crimp in the vehicles' wiring harness may result in a solenoid fault code, which could cause the engine to stop. The loss of power could lead to an accident. Injuries/Deaths: None reported. The Fix: FCA will update the affected vehicles' software and replace wire harnesses, as needed. According to FCA, owners that experience the problem can temporarily resolve the issue by restarting the vehicle. If you own one: FCA is reaching out to owners to schedule a service. Related Video: Statement: Wire Harness Crimp July 22, 2016 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 323,361 vehicles in the U.S. to update certain software and replace wire harnesses, as needed. An examination of warranty data led to an FCA US investigation that discovered an insufficient crimp in a wire harness. Such a crimp may lead to a solenoid fault code that can cause propulsion loss. The Company is unaware of any related injuries or accidents. Most vehicles in the recall population will not experience this fault code over their lifetimes. However, should the condition occur, it can typically be temporarily resolved by stopping the vehicle and re-starting its engine. Accordingly, FCA US urges customers to heed the instructions on their recall notices. Affected are certain model-year 2015 Chrysler 200 midsize sedans, Ram ProMaster City small vans, Jeep Renegade and Cherokee SUVs. Certain model-year 2014 Cherokees are also affected. A change made in the harness-manufacturing process eliminates the need to recall any vehicle built after Sept. 23, 2014. An estimated 35,511 additional vehicles in Canada are included in the campaign; as are 7,067 in Mexico; and 43,927 outside the NAFTA region. Customers will be advised when they may schedule service. Those with questions may call the FCA US Customer Care Center at 1-800-853-1403. News Source: FCAImage Credit: AOL Recalls Chrysler Jeep RAM FCA jeep renegade ram promaster city

Jeep still working to improve Cherokee's 9-speed auto

Fiat Chrysler is hoping an upcoming software update will stem the tide of consumer complaints surrounding its nine-speed automatic transmission. Owners of the 2014 Jeep Cherokee have reported a number of problems on the National Highway Traffic Safety Administration's SaferCar.gov website, since the new model and its troubled gearbox arrived way back in October 2013. The software update is "intended to keep the vehicle performing as intended, and to prevent durability issues from occurring in the future," an FCA spokesperson told Automotive News, and will be available to owners of both the 2014 to 2015 Jeep Cherokee and the 2015 Chrysler 200, which also uses the 9AT. While FCA will be notifying consumers of the update, owners can also request the software reflash if they happen into their dealer before then. Despite the widely documented problems with the transmission, the only complaints on NHTSA's website relate to the 2014 Cherokee – neither the 2015 Jeep nor the 200 have received any complaints. That bodes well as FCA prepares to begin deliveries of the 2015 Jeep Renegade and launch the Fiat 500X, both of which pair the 9AT with the 2.4-liter Tigershark four-cylinder. "We have had to do an inordinate amount of intervention on that transmission, surely beyond what any of us had forecast," FCA CEO Sergio Marchionne told Automotive News. "There are things that we have done – that we continue to do. Our proactive customer care intervention has actually increased in intensity on these vehicles in 2014, especially in the second half." What's fascinating about the 9AT's problems are that they haven't been the fault of manufacturer ZF, but have related to software that wasn't "mature" and had "teething problems," Marchionne has said previously, AN reports. With the lack of criticism for the 9AT in 2015 models and this pending software update, though, here's hoping that FCA has finally figured out its fuel-sipping gearbox. Related Video:
