Researchers who busted VW cheating say FCA's diesels dirty, too

The Wall Street Journal today reported on an upcoming report from West Virginia University's Center for Alternative Fuels Engines and Emissions, which is the same lab that investigated Volkswagen emissions cheating. The report, which will be released in a matter of weeks, alleges that 2014 and 2015 model year Jeep and Ram vehicles with diesel engines emit excess pollution. But it does not specify whether the company used defeat devices. Since the report discusses Jeep Grand Cherokees, and that engine is also available in the Ram 1500, it's safe to assume that one of the implicated engines is the EcoDiesel V6, a unit actually produced by VM Motori. It's unclear whether the report covers any of the Cummins engines used in heavier-duty Ram pickups. This report comes on the heels of a federal investigation into FCA's diesel vehicles. That investigation focused on the EcoDiesel engine used in 2014-2016 vehicles. The feds were seeking a fine of up to $4.6 billion. The EPA and the State of California also previously accused FCA of using a defeat device on the same vehicles back in January. FCA, for its part, alleges that the WVU study might have been commissioned by people interested in suing the company, and disputes the testing methodology, according to the WSJ. We've reached out to WVU to confirm which engines are implicated in its study and will update this post when we have more to share. Related Video: This content is hosted by a third party.

FCA plants skipping summer shutdown to keep up with demand

Hopefully, some FCA US factory employees don't have big plans for the usual summer shutdown, because the automaker is keeping several plants running this year. Demand is so high that the company wants to keep models rolling off the assembly lines. Four FCA US assembly plants, all the engine factories, and some locations that build transmissions are staying open throughout the summer, according to the Detroit Free Press. Usually, these sites would see a two-week shutdown for the company to retool and perform repairs. This year, factories are staying open for FCA to support its strong sales. The lines that remaining humming through the summer show an inclination toward the automaker's popular SUV's and crossovers. They include the Jefferson North Assembly Plant in Michigan that builds the Jeep Grand Cherokee and Dodge Durango; Saltillo Van Assembly in Mexico that constructs the Ram ProMaster; Toledo Assembly Complex in Ohio that produces the Cherokee and Wrangler; and Toluca Assembly in Mexico that makes the Dodge Journey and Fiat 500.

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).
