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.

Jeep Grand Cherokee SRT gets power increase, minor tweaks for 2015

As a brand within Fiat Chrysler Automobiles, SRT may have an uncertain future, but it's pumping out some seriously mean machines anyway. The supercharged Hellcat V8 may be gobbling up most of the headlines with its 707 horsepower, but even the Grand Cherokee SRT is getting some small updates for the 2015 model year.
Most importantly for many enthusiasts, the Grand Cherokee SRT is getting a slight power bump. Don't expect the 700+ hp from the Hellcat, but this SUV sees a modest 5-hp and 5-pound-feet of torque improvement to bring output to 475 hp and 470 lb-ft for its 6.4-liter V8 with an eight-speed automatic. The minor change doesn't change the sprint to 60 miles per hour, clocking in at the same 4.8 seconds, or the tow rating at 7,200 pounds. Still, more grunt is never a bad idea.
Another new addition is the Active Noise Canceling system as a standard feature for this powerful SUV. It adds four microphones around the vehicle and uses the stereo system to nullify extraneous sound. However, Jeep claims that the meaty exhaust note from the V8 still gets through into the cabin for driver enjoyment.

Refreshed Chrysler 300 SRT won't be sold in NA

It looks like it might be time to bid farewell to the V8 rumble from the Chrysler 300 SRT - at least if you live in North America. The reported change comes as Fiat Chrysler Automobiles reshuffles its ranks with the Dodge brand, re-absorbing SRT and building its muscular reputation with the Challenger and Charger Hellcat models. Meanwhile, Chrysler is taking a more mainstream approach, and that likely means the end of overt high-performance models from the division for now.
According to Automotive News, the 300 SRT will be discontinued in the US for 2015, but it won't be totally dead. Some right-hand drive markets will still get the brawny V8 sedan next year, a distinction that goes a long way toward explaining some spy shots we've seen recently.
The 300 SRT's North American demise probably shouldn't come as a total shock. In FCA's five-year plan, it says that the 300 is destined for a refresh to be unveiled later this year, presumably at the upcoming Los Angeles Auto Show. There's no mention of the SRT model in the document, though, which seems to signal its end.
