Jeep CEO details the next Wrangler's push for efficiency

Jeep CEO Mike Manley's brief for the new Wrangler is a simple one – don't mess it up. But in that pursuit of keeping things proper, the affable Englishman has revealed that the brand is trying to walk a fine line while bringing its most iconic model into the 21st century. That's most important on the car's exterior. Like other long-serving American vehicles, the Wrangler is defined by its image. But even with aerodynamics playing a bigger role on the JK's successor, Manley was adamant during a conversation with Automotive News that the boxiness will carry on. "You have to be very careful with the aero of Wrangler, because at the end of the day, it needs to be recognizable as a Wrangler," Manley told AN. "To some extent that restricts you on some of the aero that you can do." Spy photos show a more rakish windshield and fascia, both key moves to lessen the aerodynamic impact of the Jeep's traditionally brick-like design. "But with weight and a number of the changes that we've made, you're going to see that we've really pushed that vehicle forward in terms of its fuel economy." The context of that last sentence points to a weight savings, something Automotive News backs up. While the Wrangler won't go all-aluminum, its frame is going to be lighter and stronger, and it will use aluminum for certain "hang-on" body parts. But this push for weight savings won't extend to the Wrangler's intangibles. It'll still ride on a body-on-frame architecture and feature solid axles at both ends, for example. Combine Manley's comments and AN's reports with news that the Wrangler will use an eight-speed automatic and offer diesel and four-cylinder turbo power in its next generation, and it's clear Jeep is trying to make the biggest strides in decades without alienating its die-hard fans.

Some Jeep Cherokees and Chrysler 200s to get standard stop-start in 2015

Automakers the world over are striving to find ways to make their models more efficient, and Chrysler has a solution for some versions of the 2015 Chrysler 200 and 2015 Jeep Cherokee (2014 model shown). The Tigershark 2.4-liter four-cylinder in the 200 and the 3.2-liter Pentastar V6 in the Cherokee are getting a slight boost later this year thanks to the addition of Chrysler's Engine Stop-Start system as standard equipment. The company predicts modest gains - a three-percent improvement in fuel economy and a three percent reduction in CO2 emissions with the new tech compared to without it. While it's not much, those who sit in traffic a lot may see a difference.
Chrysler's stop/start system uses a high-speed starter motor to restart the vehicle in a claimed a third of a second. It works by detecting when the vehicle comes to a stop and turning off the engine. A more powerful battery maintains all of the model's accessories while it sits. When the driver lets off the brake, the car starts up again to drive away. There is even a button in the cabin to turn the ESS off, if desired.
The Jeep will be the first to receive ESS in the third quarter of this year to coincide with the start of production of the 2015 model-year version. The 200 will follow in the fourth quarter as a rolling change in production.

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:
