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).

2014 Jeep Cherokee gets official in a hurry

Automakers work very, very hard to keep their new vehicles under wraps until they can present them in exactly the way they want it - typically choreographed under the bright lights of an auto show, or perhaps with photos or video in an idyllic location. Spy shooters and leaks, in other words, keep executives and public-relations types up at night.
This is likely to be one of the most polarizing designs to come out in 2014.
Take today, for instance, when the team over at Jalopnik got a big scoop - the first undisguised shots of the 2014 Jeep Cherokee, a model whose name wasn't even officially confirmed yet. The clandestine images taken inside of a factory were blurry and didn't exactly show off the crossover's radical new contours in the same sort of flattering light that Jeep probably would've wished for its product reveal. So the Auburn Hills automaker has wisely reacted by spilling at least some of the beans on the new model, giving us these four photos and confirming the Liberty replacement's name, Cherokee.

Refreshed Chrysler 300 SRT won't be sold in NA

It looks like it might be time to bid farewell to the V8 rumble from the Chrysler 300 SRT - at least if you live in North America. The reported change comes as Fiat Chrysler Automobiles reshuffles its ranks with the Dodge brand, re-absorbing SRT and building its muscular reputation with the Challenger and Charger Hellcat models. Meanwhile, Chrysler is taking a more mainstream approach, and that likely means the end of overt high-performance models from the division for now.
According to Automotive News, the 300 SRT will be discontinued in the US for 2015, but it won't be totally dead. Some right-hand drive markets will still get the brawny V8 sedan next year, a distinction that goes a long way toward explaining some spy shots we've seen recently.
The 300 SRT's North American demise probably shouldn't come as a total shock. In FCA's five-year plan, it says that the 300 is destined for a refresh to be unveiled later this year, presumably at the upcoming Los Angeles Auto Show. There's no mention of the SRT model in the document, though, which seems to signal its end.
