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.

EU finds Jeep Grand Cherokee and Suzuki Vitara break emissions rules

AMSTERDAM — Fiat Chrysler's Jeep Grand Cherokee and Suzuki's Vitara diesel models both break emissions rules and must be fixed or face a ban on sales across Europe, the Dutch road authority ruled on Thursday. The RDW authority, acting as the reference regulator for across the European Union, said Jeep had developed a software fix and that the authority had ordered the company to recall the model across Europe to roll it out. It added Suzuki had yet to find a credible solution for the Vitara. "Suzuki must come with adequate improvement measures or the RDW will begin the process of revoking its European type approval," the RDW said in a statement, adding it had also started the process of revoking approval for the Jeep Grand Cherokee as a "precautionary measure." Regulators across the world have been testing diesel models since Volkswagen admitted in 2015 that it used illegal software to cheat U.S. emissions tests. The RDW said it had found both the Jeep Grand Cherokee and Vitara had used "prohibited emissions strategies" that led them to emit higher levels of harmful nitrogen oxide (NOx) on the road than under testing conditions. Dutch State Secretary for Infrastructure, Stientje van Veldhoven, said in a letter to parliament she would inform prosecutors of the RDW's findings. Fiat Chrysler and Suzuki could not immediately be reached for comment. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

2018 Jeep Wrangler owner’s manuals leaked, and they tell us much — but not all

If you're looking for some light reading to start your week, we have a suggestion for you. The " Owner's Manual" and the " User Guide" for the 2018 Jeep Wrangler have leaked, and have been posted on the JL Wrangler Forums. They appear to be the real deal. There's a ton of information, and many pages to pore over, but here's a little bit of what we've gleaned so far. The documents (assuming they're not just some very elaborate and convincing hoax) confirm the power sliding top, which is not removable, though the rear quarter windows are. We're not seeing any mention of a power soft top, though. There are instructions on door removal, as well as folding down the windshield. The manuals also confirm a 4WD Auto mode that shifts power between the front and rear axles as needed. What we don't appear to have yet are complete specifications. The manuals mention the 2.0-liter and 3.6-liter engines, but not their output figures. The 2.0-liter recommends premium fuel, while the 3.6-liter only needs 87 octane. Towing capacity for the two-door models is 2,000 pounds, while the four-door versions are capable of 3,500 pounds. The manuals also provide a lot of images, if you're interested in seeing the nitty gritty details of the Wrangler's various functions. Take a look, and make sure to post any interesting findings in the comments section, below. Related Video:
