FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.

2018 Jeep Wrangler First Drive Review | Improving an Icon

TUCSON, Ariz. — We crawled, with the lightest possible touch of the accelerator pedal, over a boulder-strewn mountain peak just outside of Tucson. We'd been driving for a few hours already, through city streets, along the highway, through twisty stretches just outside of Saguaro National Park. But it wasn't until we were pointed skyward, at such a severe vertical incline that we could only barely make out the hands of the trail guide ahead, that we knew Jeep had nailed the 2018 Wrangler redesign. That light-bulb moment was punctuated by the screeching steel impact of a skid plate along the jagged edge of a boulder. There's just something that feels right about a vehicle designed with purity of purpose. Leave the one-size-fits-all approach to the midsize crossover; stop attempting to be all things to all people like the midsize sedan. The problem with narrow-minded vehicles, though, is that they all require some sort of significant compromise to live with on a daily basis. With the latest version of the iconic Wrangler, Jeep set out to banish as much compromise as possible. Smoothed-out corners and lightweight materials improve efficiency, a range of engine choices opens the envelope to a larger swath of buyers, and big infotainment screens and backup cameras make the 2018 Wrangler easier to live with than ever before. But that essential purity of purpose remains intact. The latest Wrangler is better in every way than its predecessor, a fact that rings true no matter what type of terrain you're driving on. A casual observer may not notice the subtle exterior tweaks made to the 2018 Wrangler, codenamed JL, over the JK model it replaces. The round headlights, LED units on higher-end models, now cut into the outer two vertical grille slats, which are canted back just enough to make a difference in the wind tunnel. The windshield, too, is swept back further than ever before, but not so much that it messes up the Wrangler's timeless design. Hood and door latches are still externally bolted to the body — crucially allowing the doors and windshield to be removed or folded down for the pinnacle of open-air motoring — like little lumps of clay the designer forgot to smooth out. Vents in the front fenders reduce underhood pressure and keep the hood from writhing about at speed as it did on Wrangler models in the past. So picky are Wrangler customers that Jeep's decision to move the turn signals ignited a thousand threads on internet forums worldwide.

Ram and Jeep Wrangler drive Fiat Chrysler profits up 61 percent

MILAN — Italian American automaker Fiat Chrysler says fourth-quarter net profits rose by 61 percent, powered by North American sales of the all-new Ram 1500 and Jeep Wrangler. Fiat Chrysler Automobiles on Thursday reported quarterly net profits of 1.29 billion euros ($1.46 billion), compared with 804 million euros in 2017. Revenues rose 6 percent to 30.6 billion euros. North America profits grew by 19 percent to 6.2 billion euros, accounting for the lion's share of the automaker's global profits. The carmaker continued to have trouble in Asia, which swung to a loss due to market weakness in China and more competition in Fiat Chrysler's core SUV market. Europe also lost ground, with profits dipping 44 percent on lower shipments and weaker pricing, while Latin America more than doubled. Based on the company's earnings last year, 44,000 unionized U.S. auto workers will get $6,000 profit-sharing checks. That's $500 more than in 2017, but smaller than U.S. rivals Ford and General Motors. On Wednesday, GM announced that workers would get $10,750, while Ford workers will get $7,600.Related Video: This content is hosted by a third party.
