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 musters 22 MPG city, 31 highway

Production and media drive delays included, there has been no lack of press surrounding the 2014 Jeep Cherokee. With the most recent delay reportedly due to powertrain calibrations, we've been waiting to see how the Cherokee's fuel economy looks against the highly competitive compact CUV segment. Thanks to the EPA, we now know the fuel economy figures for the newest member of the Jeep family.
Arguably, the Cherokee has the most modern powertrain in its class with an updated base engine, all-new V6 and all-new nine-speed automatic transmission, but its fuel economy figures are simply on par for the segment. Still nothing to scoff at, though. According to fueleconomy.gov, front-wheel-drive Cherokee models with the base four-cylinder mill will top out the lineup with 22 miles per gallon in the city and 31 mpg on the highway; opting for four-wheel drive with this engine drops the figures to 21 city and 28 highway. Get even crazier with the option list, and the new 3.2-liter Pentastar V6 will get you 19 mpg city and 28 mpg highway in two-wheel-drive form or 19 city and 27 highway for 4WD.
If you're wondering how that stacks up among compact CUVs, head on over to Automobile Magazine for a full fuel economy breakdown for the segment. The controversially styled crossover hits dealers this month, and we'll be driving it in just a couple of weeks.

FCA CEO Mike Manley will take undefined new role after PSA merger

MILAN — Fiat Chrysler Chief Executive Mike Manley will remain with the new group set to result from a planned merger with French rival PSA-Peugeot, Chairman John Elkann said on Wednesday. In a letter to Fiat Chrysler (FCA) employees on the day the two companies announced a binding agreement for a $50 billion tie-up to create the world's fourth-largest carmaker, Elkann said he was "delighted" that the combined group would be led by current PSA CEO Carlos Tavares. "And Mike Manley, who has led FCA with huge energy, commitment and success over the past year, will be there alongside him," he said. He did not say what position Manley would hold. Elkann — who will chair the new group — said there was still much to be done to complete the merger. "Over the coming months we must work tirelessly and determinedly to fulfill all the approval requirements needed to finalize the commitment we have signed," he said.
