2014 Jeep Grand Cherokee gets surprisingly comprehensive update, new diesel power

Traditionally, automotive journalists can be heard muttering something to the effect of "Geeze, it's about time!" whenever a vehicle's midcycle refresh is revealed. As we routinely see and drive new models many months before the public even claps eyes on them in showrooms - and then go on to tweeze apart their minutia in our daily writings - perhaps some impatience is to be expected. With so much exposure to a given vehicle, it's fair to say we tire of most cars and trucks far more quickly than the average consumer.
The alterations are handsome, if not subtle touches from the "If It Ain't Broke" school of design.
Which is why we're pleased to say "Oh, is it time for that already?" when it comes to the 2014 Jeep Grand Cherokee. The current WK2 Grand Cherokee hit the market in 2011 and climbed its way into our hearts with its rugged good looks, go-anywhere capability and surprising refinement. We're not yet tired of its appearance or performance, but even so, we're very glad to see Chrysler giving its flagship Jeep some attention, including a much-anticipated diesel powertrain option and some other economy-minded measures.

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).

Jeep Renegade's development a template for new Fiat Chrysler Auto

"We figured we'd take the best of both worlds." - Ralph Gilles.
The international makeup of the 2015 Jeep Renegade will serve as a template for cooperation within the newly formed Fiat Chrysler Automobiles, Senior Vice President of Product Design Ralph Gilles said.
