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.

2014 Jeep Patriot and Compass ditch CVT for six-speed auto

It was reported in Automotive News a few months ago, but a new report on Allpar.com adds some details to news that the 2014 Jeep Compass and Patriot will get a six-speed automatic to replace the CVTs they currently use. According to a tip provided to Allpar, the 2014 models will begin production in March and be on sale sometime in the summer. The Jatco-sourced CVT in use until now - Jatco is owned by Nissan and Mitsubishi - has been often criticized, and many won't be sad to see it go.
The incoming six-speed automatic is said to be an all-wheel-drive cog-swapper that's the work of Hyundai and Magna and has been paired with the DynaMax AWD system used in the Hyundai ix35 and Kia Sportage. It won't be the only Chrysler product using a transmission with ties to Hyundai: the six-speed automatic in the Dodge Dart comes from Powertech, which is a wholly-owned subsidiary of Hyundai. With the Patriot and Compass said to be driving down the trail for the last time this year, it will be a short run for the new tranny and the rumored addition of a backup camera and power rear liftgate on the Compass.

China orders Jeep to investigate Wrangler fire risk

It's been some time since we've heard anything about fires related to the Jeep Wrangler (foreign or domestic), but it sounds like the go-anywhere SUV could be in hot water once again in China. Bloomberg is reporting that the Chinese government is ordering Jeep to investigate the matter and, in the meantime, also recommending Wrangler owners to not drive their vehicles in "extreme conditions" due to a "relatively high risk" of catching on fire.
There is no indication as to how many vehicles or which model years are affected, but the previous fire problems in both the US and China - which led to investigations but no recalls - were traced back to automatic transmission fluid leaks. The article, however, does not say what the potential problem is this time around as Jeep has not released a comment on the matter. The official notice, in Chinese, can be found here.
