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.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.

Airbag fault on 1M recalled Jeeps getting second look from NHTSA [UPDATE]

UPDATE: Here is the statement we received from Chrysler regarding NHTSA's query: "Chrysler Group LLC advised the National Highway Traffic Administration of the six reports and, in accordance with the Company's long-standing practice, is cooperating fully with the resulting investigation. Customer safety is paramount at Chrysler Group. Customers who are concerned may call 1-800-853-1403."
It appears that Jeep's repairs for nearly one million Grand Cherokees from 2002-2004 and Liberty models from 2002-2003 might not be over yet. The vehicles were first recalled in November 2012 because the front airbags could suddenly deploy without being in an accident. Now, the National Highway Traffic Safety Administration is opening a recall query into them because of reports of inadvertent activation on some already corrected vehicles.
The original problem affected over 919,000 vehicles worldwide, including 744,822 in the US, and was caused by a degrading circuit in the wires that control the airbags. In some cases the airbag warning light would come on just before the premature activation, but in other cases it would just happen. The automaker installed an "in-line jumper harness with an integrated electrical filter" meant to eliminate the power spikes believed to be the cause.
