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 and ZF issue recall on nine-speed automatic transmission

After years of complaints, German transmission manufacturer ZF is finally issuing a recall of its much maligned 9HP nine-speed automatic transmission. Although it has been criticized for a number of issues, ZF is issuing the recall to address the possibility of the transmission unexpectedly shifting into neutral. The issue covers 505,000 vehicles in the United States alone. This issue is related to an improper crimp on the transmission wiring harness. Rather than a physical fix, ZF is issuing a software update to remedy the problem. The company doesn't recommend dealers attempt to fix the crimp. Although the transmission can be found in a number of models by various manufacturers, currently only those from FCA are being recalled. This is the second recall in less than a year related to a ZF transmission shifting into neutral. FCA recently recalled more than a million vehicles worldwide because of a poorly designed shifter for ZF's 8HP eight-speed automatic. That issue may have resulted in the death of actor Anton Yelchin in June. Although there are no deaths related to this new recall, NHTSA reports that the issue has resulted in at least 10 injuries. Issues with the transmission have been known for years. A number of software updates have attempted to address various problems, making us wonder if there could be a fundamental hardware issue as the complaints span across a number of automakers. Vehicles equipped with the 9HP include 2014 and newer versions of the V6 Acura TLX, Chrysler 200, Fiat 500X, upper-level Honda Pilots, Jeep Cherokee and Renegade, Land Rover Discovery Sport and Range Rover Evoque, and Ram ProMaster City. Only FCA is issuing a recall and only on 2014 and 2015 models. Related Video: News Source: NHTSA Recalls Chrysler Fiat Jeep Safety FCA nine-speed transmission

Chrysler Recalls Jeep SUVs For Ignition Switches

The ignition switch defects that engulfed General Motors are now a rapidly growing problem at Chrysler. Chrysler said Tuesday it is recalling up to 792,300 older Jeep SUVs worldwide because the ignition switches could fall out of the "run" position, shutting off the engine and disabling air bags as well as power-assisted steering and braking. That's the same problem that has forced GM to recall more than 15 million cars over the last six months. Chrysler's recall covers 2005-2007 Grand Cherokees and 2006-2007 Commanders. The company said it is not sure exactly how many will be recalled, but said it will notify customers by mid-September. Chrysler said an outside force such as a driver's knee can knock switches out of the "run" position. Engineers are working on a fix. The Auburn Hills, Michigan-based automaker, now part of Fiat Chrysler Automobiles NV, said it knows of no related injuries and only one accident. But it said owners should keep clearance between their knees and keys until repairs are made. Chrysler has now recalled more than 1.7 million vehicles for ignition-switch problems. In June, the company added 696,000 minivans and SUVs to a 2011 recall to fix faulty ignition switches. Those recalls covered Dodge Journey SUVs and Chrysler Town & Country, Dodge Caravan and Volkswagen Routan minivans - which Chrysler made for the German automaker - from the 2007 to 2010 model years. Tuesday's recall is the outgrowth of two investigations opened by U.S. safety regulators last month as part of a broader probe into ignition-switch and air-bag problems across the auto industry. The agency wouldn't say Tuesday whether its investigation could lead to recalls at other automakers. The National Highway Traffic Safety Administration said in June that it was investigating Jeep Commanders and Grand Cherokees after getting 32 complaints that a driver's knee can hit the key fob or key chain, causing the ignition switch to move out of position. The federal investigation is still open. The agency said Tuesday that it is requesting additional information from Chrysler to ensure that its repairs will be effective. The investigations and recalls come after GM bungled an ignition-switch recall of older small cars. GM acknowledged that it knew of the ignition problem for more than a decade but failed to recall the cars until earlier this year, when it recalled 2.6 million small cars such as the Chevrolet Cobalt.
