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 facing production delay

Jeep's bold-faced new direction spearheaded by the 2014 Cherokee is facing some teething issues. According to a report by the Detroit Free Press, production start-up of the controversial new utility vehicle at its Toledo North facility is running about a month behind schedule "due to a wide range of issues." That's according to Mark Chernoby, senior vice president of engineering at Chrysler.
Chernoby maintains that the issues being encountered aren't unusual for the launch of a new vehicle - particularly one with a new powertrain - and he downplayed the delay, telling Jeep dealers that they "will have ample inventory of the midsize SUV by fall." Among the kinks being worked out? Calibrating the Cherokee's cutting-edge ZF nine-speed automatic transmission and refining assembly line tasks to make the process more efficient.
Chrysler expects to start building retail-ready versions of the Cherokee around mid-June, with official sales slated to start in September.

2018 Jeep Wrangler Spied Looking More Aerodynamic | Autoblog Minute

This week we got an early look at the 2018 Jeep Wrangler. So what we see in these spy shots, or at least we think we see, is a vehicle that?s going to use more aluminum in a bid to reduce weight and thus improve fuel economy.
