Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.

Government Ending Jeep Investigation

The government is closing its investigation into older-model Jeeps with fuel tanks that could rupture and cause fires. The National Highway Traffic Safety Administration said Friday it has "no reservations" with Chrysler Group's plans to recall the vehicles. The agency is expected to release a report on its investigation in a few weeks. The decision ends an unusually public struggle between Chrysler and NHTSA. The agency asked Chrysler to recall 2.7 million Jeeps last June, contending that their gas tanks - which are positioned behind the rear axle - were at risk of rupturing and catching fire in rear-end crashes. Involved were Grand Cherokee SUVs from the 1993 to 2004 model years and Liberty SUVs from 2002 to 2007. Chrysler initially refused to recall the vehicles. The company said the rate of fuel leaks and fires after crashes was similar to comparable vehicles that were sold during the time in question. It was the first time in two years that an automaker had refused NHTSA's request for a recall. Chrysler later agreed to recall 1.56 million of the Jeeps and install trailer hitches on them to help protect the gas tanks. The company sent notices to the remaining customers saying their vehicles were fine if they have factory-installed or Chrysler-made trailer hitches. NHTSA said late Friday that it has been in close contact with Chrysler and will monitor the recall as it continues. Chrysler has told customers that it will start installing the hitches soon. "Consumers should have their vehicles serviced promptly once they receive final notification from Chrysler,"NHTSA said in a statement. In its own statement Friday, Chrysler said, "We share NHTSA's commitment to safety." NHTSA's outgoing chief, David Strickland, told The Associated Press in an interview last month that Chrysler had convinced NHTSA that the Jeeps were no more dangerous than similar vehicles sold at that time. "Those vehicles performed at a rate similar to their peers. That is the keystone analysis as to whether something poses an unreasonable risk to safety," Strickland said. Friday was Strickland's last day at NHTSA. He is joining Venable, a law firm. NHTSA began investigating the Jeeps at the request of the Center for Auto Safety, a Washington-based advocacy group. "It is tragic that NHTSA approved Chrysler's sham trailer hitch recall for Jeeps that explode in rear impacts," the Center for Auto Safety's director, Clarence Ditlow, said Friday.

FCA's Pentastar V6 gets more power, efficiency for 2016

Already a vital member of FCA's powertrain lineup, the 3.6-liter Pentastar V6 is receiving major efficiency improvements for 2016. Thanks to a massive amount of new tech attached to the mill, fuel economy is up six percent, and torque below 3,000 rpm jumps nearly 15 percent. The updates arrive first in the 2016 Jeep Grand Cherokee, but they should proliferate to other models eventually. At least in the Grand Cherokee, the tweaks push power up five horsepower to 295 ponies. FCA's engineers went through the Pentastar from top to bottom to eke out as much efficiency as possible. For example, there's now a two-speed variable-valve lift system that can run in low- or high-lift modes. This upgrade is responsible for 2.7-percent better economy, the company claims. A new intake manifold with longer runners and updated variable-valve times also helps boost the torque output. Further improvements come from pushing the compression ratio to 11.3:1, from 10.2:1 before. Perhaps most impressive is that despite all of the innovations, the latest Pentastar actually weighs four pounds less than the current version. Beyond the Pentastar improvements, all of the FCA US gasoline engines, except for the Viper's 8.4-liter V10, will be E15-compatible for 2016. The company says that it wants to be ready for the higher ethanol content fuel's greater use in the near future.
