An inside look at Mopar's SEMA fleet

Mopar is heading to the SEMA show in Las Vegas with a fleet of customized vehicles that appeal to enthusiasts of all stripes. There's a Dodge Viper ACR concept that follows in the lineage of the supercar's great road racing past, and a custom Ram ProMaster that might just be the ultimate outdoor party machine.
We got an inside look at Mopar's cars that will be on display at the show, which also include a Dodge Challenger T/A concept, two crazy Jeeps and a Ram 2500 Outdoorsman that could change the way you camp. While these are some of our favorites, Mopar is bringing plenty to SEMA, so let us know your top choices in the comments section.

Jeep rocks the Wrangler Red Rock concept in Vegas [w/video]

The SEMA show may have once been all about dropping rides to the floor, but these days it's at least as much about jacking them up on lifted suspensions. And few show cars – or trucks, we should say – managed to embody that spirit at this year's tuner exposition quite as well as the Jeep Wrangler Red Rock you see here. The concept started out life as a Wrangler Unlimited, but instead of four doors, it has none. Or any roof, for that matter. Just a roll cage and a windscreen. What it does have are 17-inch wheels wearing 35-inch BF Goodrich tires and fitted to a suspension lifted by two inches. It also has a reinforced tailgate, power winch, tow hooks... everything, in short, that you could want or need for off-roading, and little more. As you can see, it also looks the business, with a custom hood, body-color grille, matte-finish bumpers, and a brown leather interior. Handsome as it is, though, its rugged beauty runs more than skin deep: lift off the sheetmetal and you'd find electronic locking differentials, a transfer case, and solid axles fore and aft. A more extreme take on the existing Jeep Wrangler Unlimited Rubicon Hard Rock edition, the Red Rock show truck was done up to honor the organization behind the Easter Jeep Safari that's a favorite among the legions of the Jeep faithful. And while it remains a concept only for the time being, a production version is slated to follow in time to celebrate the event's 50th anniversary next year. Related Video:

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.
