Next-gen Jeep Wrangler to get 8-speed automatic and 3.0-liter EcoDiesel

Following up on previous reports, an anonymous source within FCA has confirmed to Autoblog that the next-generation Jeep Wrangler will come to market with both a 3.0-liter, EcoDiesel V6 and ZF's critically acclaimed eight-speed automatic transmission. While this pairing makes a lot of sense (we'll explain why in a minute), until now, we only had limited reports that either item would arrive in the next-generation Wrangler. This is the first time we've heard that the eight-speed automatic and the diesel would be paired together. That said, we shouldn't be surprised by this news. FCA currently sells the Jeep Grand Cherokee and Ram 1500 with the diesel/eight-speed gearbox combo, making its inclusion in the next-gen Wrangler far from an Apollo 11-caliber feat of engineering. Naturally, we reached out to Jeep for an official comment. Spokesperson Gabrielle Schulte gave us the expected response to this kind of inquiry, telling Autoblog that FCA does not comment on future product. Jeep has flirted with the idea of a diesel Wrangler for some time, with CEO Mike Manley telling Ward's Auto just over two years ago that a Wrangler diesel was "on the radar," although at that time, we weren't certain whether it'd be the 3.0-liter EcoDiesel showing up in the rough-and-tumble off-roader. As for the eight-speed, SEC filings back in November revealed that it'd be coming to the Wrangler in 2018. Our source could not confirm which model year the 8AT/diesel would arrive in.

NHTSA upgrading Jeep Grand Cherokee, Dodge Durango headliner fire probe

The National Highway Traffic Safety Administration investigation into headliner fires experienced by a small number of Jeep Grand Cherokee and Dodge Durango owners has been upgraded to an engineering analysis, the step before the initiation of a recall. In August last year the investigation began with 146,000 Grand Cherokees from 2012 after three complaints were received, but a report on Edmunds says it has been expanded to include 593,299 vehicles covering the 2011-2013 model years for the Jeep and the Dodge Durango, which uses the same headliner assembly, because of possibly 52 incidents of fire.
In some of those incidents drivers have reported a burning odor, smoke or open flames that were contained to the headliner or migrated to another area of the passenger compartment. The culprit has apparently been found: NHTSA blaming an electrical short in the sun visor vanity light wiring, which is routed under the headliner and held in place by three screws. Chrysler began its own probe into the issue when it was first reported and is still looking into the situation while, "fully supporting the National Highway Traffic Safety Administration's investigation."

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).
