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.

The future's electric — but the present is peak gasoline. Burn some rubber! Do donuts!

I vividly remember the year 1993 as a teenager looking forward to getting my driver’s license, longingly staring into Pontiac dealerships at every opportunity for a chance to see the brand-new fourth-generation Firebird and Trans Am. Back then, 275 horsepower, courtesy of GMÂ’s LT1 5.7-liter V8 engine, was breathtaking. A few years later, when Ram Air induction systems freed up enough fresh air to boost power over 300 ponies, I figured we were right back where my fatherÂ’s generation left off when the seminal muscle car era ended around the year 1974. It couldn't get any better than that. I was wrong. Horsepower continued climbing, prices remained within reach of the average new-car buyer looking for cheap performance, and a whole new level of muscular magnitude continued widening eyes of automotive enthusiasts all across the United States. It was all ushered in by cheap gasoline prices. And as much as petrolheads bemoan the coming wave of electric vehicles, perhaps instead now would be a good time for critics to sit back and enjoy the current and likely final wave of internal combustion. Today, itÂ’s easier than ever to park an overpowered rear-wheel-drive super coupe or sedan in your driveway. Your nearest Chevy dealership will happily sell you a Camaro with as much as 650 horsepower. Not enough? Take a gander at the Ford showroom and youÂ’ll find a herd of Mustangs up to 760 ponies. Or if nothing but the most powerful will do, waltz on over to the truly combustion-obsessed sales team of a Dodge dealer and relish in the glory of a 797-hp Charger or 807-hp Challenger. Want some more luxury to go with your overgrown stable of horses? Try Cadillac, where you'll find a 668-horsepower CT5-V Blackwing. You could instead choose to wrap that huffin' and chuggin' V8 in an SUV. Or go really off the rails and buy a Ram TRX or Jeep Wrangler Rubicon 392 and hit the dunes after a quick stop at the drag strip. Go pump some gas. Burn a little rubber. Do donuts! There is nothing but your pocketbook keeping you from buying the V8-powered car of your dreams. Yes, just about every major automaker in the world has halted development of future internal combustion engines in favor of gaining expertise in batteries and electric motors. No, that doesnÂ’t mean that gasoline is going extinct. There are going to be gas stations dotting American cities and highways for the rest of our lifetimes.

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).
