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.

Weekly Recap: Hackers demonstrate auto industry's vulnerability

There's always been a certain risk associated with driving, and this week cyber security came into focus as the latest danger zone when researchers demonstrated how easily they could hack into a 2014 Jeep Cherokee from across the country. The incident raised concerns over the vulnerability of today's cars, many of which double as smartphones and hot spots. During the now-infamous experiment, Chris Valasek and Charlie Miller infiltrated the Jeep's cellular connection and were able to control the infotainment system, brakes, and other functions. The hackers told the Jeep's maker, FCA US, of their findings last year, the company devised a software fix. Though Valesek and Miller hacked a Cherokee (like the one shown above), several FCA products, including recent versions of the Ram, Grand Cherokee, Dodge Durango, and Viper were also affected, illustrating potentially wide exposure that could reverberate across the sector. "For the auto industry, this is a very important event and shows that cyber-security protection is needed even sooner than previously planned," Egil Juliussen, senior analyst and research director for IHS Automotive, wrote in a research note. "Five years ago, the auto industry did not consider cyber security as a near-term problem. This view has changed." Hours after the Cherokee hacking incident was publicized on Tuesday, Sens. Ed Markey (D-Mass) and Richard Blumenthal (D-Conn) introduced legislation to direct the National Highway Traffic Safety Administration and Federal Trade Commission to establish national standards for automotive cyber security. The bill also would require vehicles to have a cyber-rating system to alert consumers how well their cars' privacy and security are defended. "Drivers shouldn't have to choose between being connected and being protected," Markey said in a statement. "We need clear rules of the road that protect cars from hackers and American families from data trackers." Though FCA and its Jeep Cherokee were in the spotlight this time, they were just the latest to showcase how automotive technology has advanced faster than safety and regulatory measures. IHS forecasts 82.5 million cars will be connected to the internet by 2022, which is more than three times today's level. "Cyber-security will become a major challenge for the auto industry and solutions are long overdue," Juliussen said.

This is the face of the 2018 Jeep Wrangler JL

These images come from a purported Jeep dealer meeting and show a poster detailing the brand's future lineup. Along with a look at the range-topping Grand Wagoneer, we can see the next-generation Wrangler, code-named JL, and its updated design front and rear. To the surprise of no one, the Wrangler will keep its seven-slot grille and round headlights. To those it adds some modern updates, like the LED light bars on the leading edge of the front fenders. (Given the 2017 LED headlight upgrade, we can bet the low- and high-beams also will use LED tech.) The taillights get an X design like those on the Renegade crossover. The overall shape seems to be a bit more tapered and smoothed, which is most evident in the shape of the sides of the windshield. We know from spy photos that the windshield has been laid back more, likely leading to improved aerodynamics and reduced fuel consumption. As a refresher, we expect the 2018 Wrangler to again come in two-door and Unlimited four-door models. It will have at least one gas engine, including a new turbocharged Hurricane four-cylinder, as well as a diesel option. Most if not all of the engines will be paired with a nine-speed automatic transmission, and a manual is likely to be retained on at least some models. A pickup version has also been confirmed. The new Wrangler is likely to be shown in early 2017, possibly at the Detroit auto show in January.
