Fiat Chrysler Automobiles recalls nearly 750k vehicles in two campaigns

Fiat Chrysler Automobiles is recalling a total of 747,817 vehicles in the US in two separate campaigns recently added to the National Highway Traffic Safety Administration database.
The first one covers about 434,581 units of the Chrysler 300, Dodge Charger, Challenger, Durango, and Jeep Grand Cherokee from the 2011-2014 model years with electric hydraulic power steering, the 3.6-liter V6 engine and a 160 amp alternator, according to FCA. In the affected vehicles, it's possible for the alternator to fail without warning and possibly cause the car to stall. According to the documentation submitted to NHTSA, the automaker began investigating the problem in August 2014 and has found possible evidence of one crash caused by the failures but no known injuries.
Customers will begin receiving notification about the recall next month, and obviously the repairs will be done at no cost to them.

Next-gen Jeep Wrangler to pack 300-hp Hurricane turbo four

Fiat Chrysler has been working for some time now on a new turbocharged four-cylinder engine. Dubbed "Hurricane," the engine is now said to produce nearly 300 horsepower. And its first application could be in the next-generation Jeep Wrangler. With that much power coming from such a small engine, the Hurricane would offer an even higher level of specific output than the 1.75-liter engine in the Alfa Romeo 4C – one of FCA's highest-stressed engines – far eclipsing the 4C's 120 horsepower per liter with 150 hp/l. By way of comparison, the latest 2.0-liter, four-cylinder version of Ford's EcoBoost engine produces "only" 245 hp (122.5 hp/l). The 2.0-liter turbo four in the latest Mercedes-AMG CLA45 and GLA45, however, produces 375 hp. To get so much out of so little an engine, FCA will utilize a twin-scroll turbocharger and variable valve timing. That could make it ideally suited towards a compact performance model, but according to Automotive News, its first application could be in the new the Wrangler. The larger 3.6-liter Pentastar V6 produces 285 hp, nearly as much as the Hurricane will. But with a smaller engine, an eight-speed transmission, and aluminum construction, the new Jeep will likely benefit from dramatically-improved fuel consumption. Related Video:

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).
