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.

Chrysler to accelerate production of 2013 Ram and V6 engines

Chrysler is adding a third shift at its Warren Truck plant to meet demand for the new 2013 Ram pickup. And with tight supplies of its Pentastar V6, the company is also boosting output at its Mack Engine plant.
The expansions will add 1,250 jobs and are part of a $238 million investment by Chrysler in the Detroit area. Warren's third shift will begin work sometime in the spring, a Chrysler rep told Automotive News. Mack's increased Pentastar production a could include both 3.6 and 3.2-liter engines.
The company says it also plans to invest $40 million in its Trenton Engine plant to allow for production of a 3.2-liter V6 as well as the Tigershark inline-four for the upcoming Jeep Liberty replacement.

Chrysler recalling 31k SUVs and vans

Chrysler is issuing recalls covering roughly 31,700 vehicles worldwide due to two separate problems. In both cases the company believes that most of the affected vehicles are either still on, or in transit to, dealer lots.
One recall covers roughly 10,700 Dodge Durango, Jeep Cherokee, Grand Cherokee and Grand Cherokee SRT models from the 2014 model year built between January 16 and April 17, 2014. The SUVs need a software update for the cruise control. It's possible that when the cruise is on and the driver presses on the throttle, the acceleration could last a second after the pedal is released or two seconds for the SRT. Afterward, they return to the speed originally set by the driver.
Chrysler says it isn't aware of any accidents, injuries or even reported incidents of this happening in the real world. Also, in all cases, if the driver presses on the brake, the cruise shuts off. The automaker believes that there are about 6,100 affected SUVs in the US, 950 in Canada, 425 in Mexico and 3,200 outside of North America. The software upgrade will be ready shortly, the company says.
