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).

2016 Jeep Wrangler recalled over impact sensor wiring

Fiat Chrysler just announced a pair of recalls totaling nearly 311,000 units. The bigger recall affects certain 2016 and 2017 model year Jeep Wranglers. Although, since FCA claims all of the affected 2017s are in the company's hands, really, only 2016 owners should pay attention here. The affected Wranglers suffer from an issue where wiring disconnects from impact sensors in certain types of crashes, potentially preventing the airbags and pretensioners from activating. FCA uncovered the problem in what its press release calls "a routine, in-house crash test" and claims "service availability is imminent." The affected Jeeps require a simple rewiring. The other recall, announced Tuesday, is more of a fleet issue, affecting 2007 to 2013 model-year Ram 2500 and 3500 pickups and 3500, 4500, and 5500 chassis cabs and 2011 to 2014 Dodge Charger Pursuit police vehicles. There's a problem with "premature diode wear" in alternators that are subject to "frequent load cycling, at or near maximum amperage, [or] in hot ambient temperatures." Affected alternators could short out, causing a vehicle to stall or potentially catch fire. FCA lists 182,743 affected Wranglers in the US, 18,011 in Canada, 3,087 in Mexico, and 20,948 in global markets. The Ram/ Charger Pursuit recall lists 74,833 vehicles in the US, 10,077 in Canada, 1,088 in Mexico, and 134 outside the NAFTA region. Of all those vehicles, the Jeep recall hasn't caused any injuries or fatalities, while FCA says it's aware of one "potentially related injury" and no accidents due to its fleet vehicle recall. FCA says it will notify owners/operators of affected vehicles when service appointments are available. As per usual, all the work is free of charge. Related Video:
