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).

164K Jeep Cherokees recalled to protect liftgate from moisture

FCA is recalling 164,003 examples of the 2014 and 2015 Jeep Cherokee because moisture can damage the power liftgate controls on models that are equipped with that feature. Regionally, this includes 99,436 of them in the US, 13,195 in Canada, 2,406 in Mexico, and 48,966 outside of NAFTA. The problem came to light after the automaker started investigating a fire in one of the SUVs. There were no injuries, though. According to FCA US' research, the power hatch's control module potentially can be exposed to water. This can cause a short circuit and possibly a fire, as in this case. Until the issue is repaired, the company is advising owners to keep the cargo area dry on Cherokees equipped with this feature. To fix things, dealers will install a shield around the controls to protect them from moisture and will replace any modules showing exposure to water. Statement: Water-Shield Installation June 24, 2015 , Auburn Hills, Mich. - FCA US LLC is voluntarily recalling an estimated 99,436 SUVs in the U.S. to install shields that protect their power liftgate control modules, and related components, from moisture. FCA US LLC began an investigation after learning of a reported vehicle fire. The probe revealed power liftgate control modules in certain SUVs may be inadvertently exposed to water. This may cause a short-circuit, creating a fire hazard. However, the Company is unaware of any related injuries or accidents. The campaign affects model year 2014 and 2015 Jeep Cherokee SUVs, but is limited to vehicles equipped with power liftgates. An estimated 13,195 customers are affected in Canada, along with an estimated 2,406 customers in Mexico and 48,966 outside the NAFTA region. The estimated total recall population is 164,003. All affected customers will be advised when they may schedule service. If the modules show signs of water exposure, they will be replaced. All recall-related work will be performed free of charge. In the interim, the cargo areas of 2014-15 Cherokees equipped with power liftgates should be monitored and kept dry. Customers with questions may call the FCA US Customer Information Center at 1-800-853-1403.
