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.

Chrysler investing $20M in Toledo plant to support 9-speed auto production

In 2011, Chrysler announced a $72-million investment in its Toledo Machining Plant to modernize production of the eight- and nine-speed torque-converters for automatic transmissions made there. That upgrade work won't be finished until Q3 of this year, but Chrysler has already announced a further $19.6-million investment to increase production capacity for the nine-speeders.
The extra units will be necessary because the nine-speed transmission they'll be mated to is going into three popular models: it will debut on the 2014 Jeep Cherokee, then go into the Chrysler 200 and Dodge Dart. The company predicted that this year alone it would sell 200,000 units equipped with the nine-speed tranny, and it is spending some $374 million in addition to the investment in Toledo to upgrade production capacity for it.
The work attached to this new investment won't begin until Q3 of 2014, and it will be finished by the end of that year. There's a press release below with all the details.

Chrysler, Nissan looking into claim that their cars are industry's most hackable

A pair of cyber security experts have awarded the ignominious title of most hackable vehicles on American roads to the 2014 Jeep Cherokee, 2014 Infiniti Q50 and 2015 Cadillac Escalade.
Charlie Miller and Chris Valasek are set to release a report at the Black Hat hacking conference in Las Vegas, Automotive News reports. The two men found the Jeep, Caddy and Q50 were easiest to hack based not on actual tests with the vehicles, but a detailed analysis of systems like Bluetooth and wireless internet access - basically, anything that'd allow a hacker to remotely gain access to the vehicle's systems.
Considering this lack of hands-on testing, the pair acknowledge that "most hackable" could be a relative term - they point out that the vehicles may actually be quite secure.
