Chrysler taking big risk snubbing NHTSA

Maker Insists Feds Overstate Risk Of Fires With Grand Cherokee, Liberty Models
It's not often that recall stories make it above the fold, in that old newspaper parlance, but when one shows up as the lead story on the network evening news programs, you know it's something big.
And so it is with Chrysler snubbing its nose at a request by the National Highway Traffic Safety Administration to recall 2.7 million Jeeps the feds insist are at risk of potentially catastrophic fuel tank fires in a rear-end collision.

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 Patriot and Compass ditch CVT for six-speed auto

It was reported in Automotive News a few months ago, but a new report on Allpar.com adds some details to news that the 2014 Jeep Compass and Patriot will get a six-speed automatic to replace the CVTs they currently use. According to a tip provided to Allpar, the 2014 models will begin production in March and be on sale sometime in the summer. The Jatco-sourced CVT in use until now - Jatco is owned by Nissan and Mitsubishi - has been often criticized, and many won't be sad to see it go.
The incoming six-speed automatic is said to be an all-wheel-drive cog-swapper that's the work of Hyundai and Magna and has been paired with the DynaMax AWD system used in the Hyundai ix35 and Kia Sportage. It won't be the only Chrysler product using a transmission with ties to Hyundai: the six-speed automatic in the Dodge Dart comes from Powertech, which is a wholly-owned subsidiary of Hyundai. With the Patriot and Compass said to be driving down the trail for the last time this year, it will be a short run for the new tranny and the rumored addition of a backup camera and power rear liftgate on the Compass.
