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.

In Michigan, car hackers could face life imprisonment

Car hackers may not want to mess with vehicles in and around the Motor City. A pair of Michigan lawmakers introduced legislation Thursday that would punish anyone who infiltrates a vehicle's electronic systems with penalties as harsh as life imprisonment. Senate bill 927 says that "a person shall not intentionally access or cause access to be made to an electronic system of a motor vehicle to willfully destroy, damage, impair, alter or gain unauthorized control of the motor vehicle." Offenders will be deemed guilty of a felony, and may be imprisoned for any number of years up to life in prison. The proposed legislation is one of the first attempts nationally to address the consequences for car hacking, which has become a top concern throughout the auto industry. Critics have accused executives of being slow to respond to the threats, which were first known as long as six years ago but gained attention last July when a pair of researchers remotely controlled a Jeep Cherokee. In January, the industry established an Information Sharing and Analysis Center to collectively evaluate security measures and counter breaches. But the Michigan bill isn't noteworthy only because of the life penalty prescribed; it's noteworthy for what's missing in its details. Language in the bill doesn't delineate between independent cyber-security researchers and criminals who intend to inflict harm or havoc. Under its provisions, it's possible Charlie Miller, pictured below, and Chris Valasek, the researchers who demonstrated last summer that the Cherokee could be remotely commandeered and controlled, could face life behind bars. Provisions of the legislation that prevent a person from "altering" the motor vehicle could ensnare car enthusiasts or gearheads who tinker with electronic systems to boost performance, increase fuel efficiency or add aftermarket features. In that context, Senate Bill 927 seems like the latest measure in a running feud between independent researchers, gearheads and big automakers. Car companies don't like third parties poking around their electronic systems and would prefer the researchers not reveal security weaknesses. Researchers, on the other hand, say many carmakers are either slow to fix or unwilling to repair security holes unless they're able to publish their findings.

From Maseratis to rental cars | Autoblog Podcast #511

On this week's podcast, Mike Austin and David Gluckman are in a huddle room (again), because the studio was already taken (again). We talk about the all-wheel-drive Dodge Challenger GT (again), as well as the Jeep Wrangler, Maserati Levante, Miata RF (again), and then David waxes poetic on mediocre rental cars (or similar). The episode wraps up with the traditional doling out of Spend My Money buying advice, with some input from an S2000 owner on advice discussed last time. The rundown is below. Remember, if you have a car-related question you'd like us to answer or you want buying advice of your very own, send a message or a voice memo to podcast at autoblog dot com. (If you record audio of a question with your phone and get it to us, you could hear your very own voice on the podcast. Neat, right?) And if you have other questions or comments, please send those too.
