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.

Recharge Wrap-up: EV torque secrets, UC Davis maps future of biofuels

A UC Davis white paper maps out "Three Routes Forward for Biofuels," balancing investment risk with carbon benefits. The first option is "incremental," in which we tinker with the existing biofuel manufacturing infrastructure for small improvements over time. The "transitional" plan suggests integrating cellulosic production and other innovations with existing operations. The third route, called "leapfrogging," would mean building refineries based on new technology such as cellulosic and algae-based biofuels. The paper suggests ways the US could use these three routes together in different areas, and predicts the payoffs in terms of carbon emissions could be significant if the right people are willing to risk the capital. After all, financial advisers are always telling investors to diversify their portfolios to manage risk and rewards in the same way.

The seventh round of the inaugural all-electric race season, which was moved from Los Angeles to the streets of Long Beach, will offer fans free grandstand and general admission. The race, which takes place on April 5, 2015, will use a 1.6-mile portion of IndyCar's Grand Prix of Long Beach. Read more at LA Times. Polaris is now offering its 2015 GEM electric vehicles, including the new street-legal eM1400 LSV. The passenger and utility vehicles come in two- to six-passenger configurations, many of which are street legal on roads with posted speed limits of up to 35 miles per hour. The eM1400 LSV utility vehicle seats two, offers 1,250 pounds of payload, 1,250 pounds of towing capacity, a top speed of 25 mph and a range of up to 45 miles. Its on-board charger plugs into any standard 110-volt outlet. Read more at Hybrid Cars and check out all the different configurations yourself at the Polaris website. In EVs, more torque does not always equal faster. Green Car Reports found this out when driving the Fiat 500e (with 147 pound-feet) against the similarly weighted Chevrolet Spark EV (with 400 pound-feet). The secret is, at least in part, in the gearing. The Fiat has a 9.6:1 reduction gear, making it quicker at lower speeds despite having far less available torque, while the Chevy uses a 3:1 ratio. The trade-off though, is in top speed. Furthermore, Chevy electronically limits the torque delivery at low speeds, as 400 pound-feet is a lot of launch for the little Spark EV to handle.

Recharge Wrap-up: Fiat 500X EV spotted? Senators request biodiesel increase

A group of 32 senators is asking the EPA to approve increased biodiesel volumes in the Renewable Fuel Standard. Delays in approving the RFS for 2014 forward is causing problems for the fuel produces affected by the law. "EPA's delays are endangering our industry," says Imperium Renewables CEO John Plaza. "Biofuel facilities around the nation are sitting idle, workers are being laid off, and some producers have been forced out of business entirely." Producers feel the EPA is underestimating domestic biodiesel production, and are concerned about importing fuel from Argentina. Read more in the press release below. Fiat Chrysler will help Israel develop a natural gas vehicle. The automaker, along with Iveco and Magneti Marelli, signed a memorandum of understanding with Israel's Prime Minister's Office as part of the Israel Fuel Choices Initiative. They are also considering extended research and development relationship with Israeli companies for alternative fuels and smart mobility. Israel seeks to become a hub for alternative fuel technology.

The photos, sent by a reader to Green Car Reports, show a camouflaged Fiat 500X that appears to lack a tailpipe, suggesting it could be an EV. It was photographed on its way to Chrysler's SRT Engineering Center, which builds specialized, low-volume vehicles. The gas-powered 500X debuted in North America at the Los Angeles Auto Show last fall, so camouflage seems a bit unusual at this point if it's just a standard powertrain. It's possible the car could be sold mainly in California to comply with the state's zero-emissions requirements for automakers.

The senators expressed concern about the agency's delays in implementing the RFS standards for 2014, 2015 and 2016, noting that the delays have created tremendous uncertainty for the U.S.
