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.

Texan finds creative way to clear highway fast lane

Few things are as infuriating as someone driving slow in the fast lane. A Jeep driver from Texas found himself in just such a predicament near Fort Worth, and came up with a creative way to urge the offending lane-blocker to get a move on. Machine, a YouTuber and off-road enthusiast from the Lone Star State, posted some dashcam footage to his account back in March which showed him stuck behind a slow driver. He was attempting to pass a slow-moving bobtail Peterbilt tractor when he got hung up by a white Ford Econoline squatting in the passing lane. On his YouTube page, Machine stated that the van, which apparently belonged to a plumbing company, was traveling along between 60 and 70 miles per hour along a stretch of highway with a stated speed limit of 70 mph. Confronted with the slow-moving van blocking the left lane, and traffic in the right lane, Machine called the number on the back of the Econoline and politely asked him to get out of the way. In the Econoline, the passenger picked up and was momentarily confused as Machine asked him to ask his driver to move out of the lane and let traffic pass. The van sped up, passed a tractor-trailer, and got out of the way, much to the relief of the traffic behind him. According to CBS news, 38 states have laws on the books to punish slow drivers squatting in the passing lane. In five of those states, the fine is upwards of $1000, and 22 states classify it as a misdemeanor.
