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 rear-mounted fuel tank controversy

Jeep mulling power top for next Wrangler

Jeep is hard at work on the next-generation Wrangler, though the truck is still a few years from hitting the trails. The new model will still be aimed at off-roaders, but rumors suggest it will be a little more comfortable than previous versions to appeal to more people.
According to Road and Track, Jeep is developing a power-retractable top as an expensive option for the Wrangler. There is no word if the top in question is a sliding canvas rollback like the ones found on many European vehicles or a full convertible hardtop or softtop, nor do we know whether it would be made available on two- or four-door models. It might be a nice feature for some buyers but would certainly add complexity to a truck already known for its ruggedness. We asked Jeep for confirmation, but Jeep spokesperson Todd Goyer could only remind us that the company "can't comment about future products."
In news that is likely to irk the faithful, R&T reports the next model may also ditch its folding windshield for improved safety and possibly even get rid of its rear-mounted, full-size spare tire. The new Wrangler won't go completely soft, though, and will reportedly still feature removable doors and solid axles.
