2014 Jeep Grand Cherokee gets surprisingly comprehensive update, new diesel power

Traditionally, automotive journalists can be heard muttering something to the effect of "Geeze, it's about time!" whenever a vehicle's midcycle refresh is revealed. As we routinely see and drive new models many months before the public even claps eyes on them in showrooms - and then go on to tweeze apart their minutia in our daily writings - perhaps some impatience is to be expected. With so much exposure to a given vehicle, it's fair to say we tire of most cars and trucks far more quickly than the average consumer.
The alterations are handsome, if not subtle touches from the "If It Ain't Broke" school of design.
Which is why we're pleased to say "Oh, is it time for that already?" when it comes to the 2014 Jeep Grand Cherokee. The current WK2 Grand Cherokee hit the market in 2011 and climbed its way into our hearts with its rugged good looks, go-anywhere capability and surprising refinement. We're not yet tired of its appearance or performance, but even so, we're very glad to see Chrysler giving its flagship Jeep some attention, including a much-anticipated diesel powertrain option and some other economy-minded measures.

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.

7 months later, Jeep 'trailer hitch' recall still stalled

For the past few years, Chrysler and its CEO, Sergio Marchionne, have gone head-to-head with the National Highway Traffic Safety Administration and its boss, David Strickland, over the government safety agency's request for Chrysler to recall almost three-million Jeep vehicles due to what NHTSA says is a safety issue that has caused at least 51 deaths. After a three-year investigation and Chrysler's initial refusal to issue a recall because it deemed the vehicles safe and built to the day's federal requirements, last summer, the two parties compromised on a "voluntary campaign" to inspect 1.56 million vehicles, those being the 1992 to 1998 Grand Cherokee and 2002 to 2007 Liberty.
Those vehicles were designed with their gas tanks between the rear axle and the bumper, and NHTSA says that in rear-end collisions, damage to the fuel tank has caused fires responsible for those 51 deaths. The compromise reached last summer was that Chrysler would inspect 1.56 million vehicles and, "if necessary, provide an upgrade to the rear structure of the vehicle." Practically speaking, that meant Chrysler would replace aftermarket trailer hitches, but would take no action if a vehicle had a factory-installed hitch or an aftermarket hitch from Mopar.
A report in The Detroit News says the "voluntary campaign" is just now getting under way, with Chrysler saying last week that the design of the replacement part had been finalized and it was tooling up "to deliver the required volume." Seven months later, still in question is whether NHTSA will crash-test the fix engineered by Chrysler, noteworthy because not only did the vehicles in question pass every safety standard necessary to be cleared for sale at the time, there are still questions (to those of us on the outside) as to how the Jeeps at issue fare among their peers in such incidents. Either way, Chrysler and NHTSA apparently still disagree on the efficacy of the remedy itself: the carmaker says it might help in low-speed crashes but not high-speed collisions, a position the NHTSA is at odds with. All of this means the campaign doesn't yet have an end in sight.
