Chrysler axes old V6s, goes all-Pentastar

Old technology has a way of lingering on, particularly at Chrysler headquarters in Auburn Hills. So while the Pentastar V6 has replaced the older engine architecture in just about every application, it still soldiered on in some export markets. But the introduction of a new 3.0-liter Pentastar V6, produced in Michigan and meant only for the Chinese market, has put the final nail in the old engine's coffin.
Fitted into the 2014 Jeep Grand Cherokee and Jeep Wrangler just introduced to China at the Chengdu Motor Show, the downsized six uses the same architecture as the larger 3.6-liter Pentastar V6. But because of its 2,997cc capacity, it can be exported to China without the increased duty the 3.6-liter or even 3.2-liter Pentastar engines would incur. The 3.0-liter V6 develops 230 horsepower at 6,350 rpm and 210 pound-feet at 4,400 rpm.
Admittedly, it's unlikely, but even though the engine was said to be created solely to undercut tax thresholds in China and Europe, the 3.0-liter Pentastar has recently surfaced in rumors of an application here: as the boosted heart of a potential Cherokee SRT with anywhere from 375 to 410 hp.

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.

Jeep shows off Moab Easter Safari concepts crawling the red rocks

While most brands are busy showing off in New York, Jeep headed out to Moab for the Easter Jeep Safari with the company's fleet of 2013 concepts. This year saw the Grand Cherokee Trailhawk II, Wrangler Mopar Recon, Wrangler Stitch, Wrangler Sand Trooper II, Wrangler Flattop and Wrangler Slim Concepts tackle the rocks and sand, and Jeep was kind enough to bring along a camera crew to film the machines rolling over a few obstacles. The result is the video below, though don't expect to see too much hardcore off road action.
Instead, the quick clip features more than a few interviews with Jeep executives, including Jeep Head of Product Design Mark Allen, explaining what makes the Easter Jeep Safari so important. You can check out the quick clip below for yourself, and be sure to thumb through our galleries of the concepts as well.
