2015 Jeep Cherokee finds a bit more fuel mileage thanks to stop/start and aero tweaks

Just a year after it burst onto the scene, Jeep has already made a pretty substantial addition to its V6-powered Cherokee, which has proven to be an extremely popular seller so far for the brand, adding a new stop-start system for the midsize, off-road-ready CUV.
The addition of stop-start included a few aerodynamic tweaks to the Cherokee's polarizing body, resulting in a wallet-pleasing increase in fuel economy. According to the EPA, the front-drive, V6-powered Jeep will now return 21 miles per gallon in the city and 29 mpg on the highway, up from 19 city and 28 highway. Four-wheel-drive, V6-powered Cherokees, meanwhile, will now return 20 mpg in the city and 28 mpg on the highway, up from 19 mpg in the city and 27 mpg.
With 271 horsepower, 239 pound-feet of torque and these newly enhanced figures, it's refreshing to see a larger, naturally aspirated engine that is still able to take the fight to today's crop of small-displacement, turbocharged four-cylinders.

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).

Auto Mergers and Acquisitions: Suicide or salvation?

We love the Moses figure. A savior riding in from stage right with the ideas, the smarts, and the scrappiness to put things right. Alan Mullaly. Carroll Shelby. Lee Iacocca. Andrew Carnegie. Steve Jobs. Elon Musk. Bart Simpson. Sergio Marchionne does not likely view himself with Moses-like optics, but the CEO of Fiat Chrysler Automobiles recently gave a remarkable, perhaps prophetic interview with Automotive News about his interest and the inevitability of merging with a potential automotive partner like General Motors. Marchionne has been overtly public about his notion that GM must merge with FCA. For a bit of context, GM sold 9.9 million vehicles in 2014, posting $2.8 billion in net income, while FCA sold 4.75 million units and earned $2.4 billion in net income, painting a very rosy FCA earnings-to-sales picture. But that's not the entire picture. Most people in the auto industry still remember the trainwreck that was the DaimlerChrysler "merger" written in what turned out to be sand in 1998. It proved to be a master class in how not to fuse two companies, two cultures, two continents, and two management teams. Oh, it worked for the two individuals at both helms pre-merger. They got silly rich. And the industry itself was in a misty romance at the time with mergers and acquisitions. BMW bought Rolls-Royce. Volkswagen Group bought Bentley, Bugatti, and Lamborghini, putting all three brands into their rightful place in both products and positioning. No marriages there, so no false pretense. Finally, Nissan and Renault got married in 1999. A successful marriage requires several rare elements in this atmosphere of gas fumes and power lust. But a successful marriage requires several rare elements in this atmosphere of gas fumes and power lust, the principle part being honesty. Daimler and Chrysler lied to each other. The heads of each unit, the product planners, and finance all presented their then-current and long-range forecasts to each other with less-than-forthright accuracy. Daimler was the far greater equal and no one from the Chrysler side enjoyed that. The cultures were entirely different, too, and little was done to bridge that gap. Which brings me back to the present overtures by Marchionne to GM. "There are varying degrees of hugs," Marchionne stated in the Automotive News piece. "I can hug you nicely, I can hug you tightly, I can hug you like a bear, I can really hug you." Seriously?
