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.

Researchers who busted VW cheating say FCA's diesels dirty, too

The Wall Street Journal today reported on an upcoming report from West Virginia University's Center for Alternative Fuels Engines and Emissions, which is the same lab that investigated Volkswagen emissions cheating. The report, which will be released in a matter of weeks, alleges that 2014 and 2015 model year Jeep and Ram vehicles with diesel engines emit excess pollution. But it does not specify whether the company used defeat devices. Since the report discusses Jeep Grand Cherokees, and that engine is also available in the Ram 1500, it's safe to assume that one of the implicated engines is the EcoDiesel V6, a unit actually produced by VM Motori. It's unclear whether the report covers any of the Cummins engines used in heavier-duty Ram pickups. This report comes on the heels of a federal investigation into FCA's diesel vehicles. That investigation focused on the EcoDiesel engine used in 2014-2016 vehicles. The feds were seeking a fine of up to $4.6 billion. The EPA and the State of California also previously accused FCA of using a defeat device on the same vehicles back in January. FCA, for its part, alleges that the WVU study might have been commissioned by people interested in suing the company, and disputes the testing methodology, according to the WSJ. We've reached out to WVU to confirm which engines are implicated in its study and will update this post when we have more to share. Related Video: This content is hosted by a third party.

In Michigan, car hackers could face life imprisonment

Car hackers may not want to mess with vehicles in and around the Motor City. A pair of Michigan lawmakers introduced legislation Thursday that would punish anyone who infiltrates a vehicle's electronic systems with penalties as harsh as life imprisonment. Senate bill 927 says that "a person shall not intentionally access or cause access to be made to an electronic system of a motor vehicle to willfully destroy, damage, impair, alter or gain unauthorized control of the motor vehicle." Offenders will be deemed guilty of a felony, and may be imprisoned for any number of years up to life in prison. The proposed legislation is one of the first attempts nationally to address the consequences for car hacking, which has become a top concern throughout the auto industry. Critics have accused executives of being slow to respond to the threats, which were first known as long as six years ago but gained attention last July when a pair of researchers remotely controlled a Jeep Cherokee. In January, the industry established an Information Sharing and Analysis Center to collectively evaluate security measures and counter breaches. But the Michigan bill isn't noteworthy only because of the life penalty prescribed; it's noteworthy for what's missing in its details. Language in the bill doesn't delineate between independent cyber-security researchers and criminals who intend to inflict harm or havoc. Under its provisions, it's possible Charlie Miller, pictured below, and Chris Valasek, the researchers who demonstrated last summer that the Cherokee could be remotely commandeered and controlled, could face life behind bars. Provisions of the legislation that prevent a person from "altering" the motor vehicle could ensnare car enthusiasts or gearheads who tinker with electronic systems to boost performance, increase fuel efficiency or add aftermarket features. In that context, Senate Bill 927 seems like the latest measure in a running feud between independent researchers, gearheads and big automakers. Car companies don't like third parties poking around their electronic systems and would prefer the researchers not reveal security weaknesses. Researchers, on the other hand, say many carmakers are either slow to fix or unwilling to repair security holes unless they're able to publish their findings.
