Weekly Recap: Toyota propels hydrogen fuel cells

Toyota is serious about hydrogen fuel cells, and it wants the auto industry to follow suit. The Japanese automaker said this week it's releasing 5,680 fuel cell patents from around the world, including technologies used on its upcoming sedan, the 2016 Mirai. The move is unusual, but not unprecedented, as Tesla similarly released its electric vehicle patents last year. The idea for Tesla, and now for Toyota, is to spur development of alternative propulsion. "By eliminating traditional corporate boundaries, we can speed the development of new technologies and move into the future of mobility more quickly, effectively and economically," said Bob Carter, Toyota Motor Sales senior vice president of automotive operations, in a statement. Toyota's fuel cell patents will be free to use through 2020, though patents related to producing and selling hydrogen will remain open forever. Toyota said it would like companies that use its patents to share their own hydrogen patents, but won't require it. "What Toyota's doing is really a logical move, and really a good move for the industry," Devin Lindsay, principal powertrain analyst with IHS Automotive, told Autoblog. The announcement was made at the Consumer Electronics Show in Las Vegas. It comes as Toyota prepares to launch the hydrogen-powered Mirai in a limited number late this year in California. The launch will be extended to the Northeastern United States next year. Toyota also has announced plans to support networks of fueling stations in each region to try to smooth consumer adoption. The Mirai has a 300-mile range on a tank of hydrogen, and it takes about five minutes to refill. Fuel cells have been receiving increased attention recently, and Audi and Volkswagen debuted hydrogen-powered cars at the 2014 Los Angeles Auto Show. Honda, another proponent of the technology, also showed its updated FCV concept in November in Japan. The company, however, has delayed its fuel cell sedan a year until 2016. Like Toyota, Honda says its hydrogen-powered car will have a range of 300 miles or more. Meanwhile, Hyundai currently offers leases for fuel-cell powered Tucsons, which have a 265-mile range, in Southern California. Despite the optimism some automakers have for fuel cells, the technology still faces barriers. A lack of filling stations has long held it back, and many consumers are not familiar with the potential benefits.

Dodge Durango could get eTorque mild hybrid system in 2020

The 2020 Dodge Durango appears slated to get a mild-hybrid powertrain option. That's the word from moparinsiders.com, which unearthed the news from documents relating to contract negotiation between the FCA and the UAW. Although the documents give no further details, it's a pretty safe bet that we're talking about Chrysler's eTorque mild-hybrid system, which was introduced on the Ram 1500 pickup and has since been extended to the Jeep Wrangler. Currently, the Wrangler offers the eTorque system on the 2.0-liter inline-four and the 3.6-liter Pentastar V6, both on the Sahara model only, while the Ram 1500 makes the mild-hybrid system standard with the 3.6-liter V6 and an option with the 5.7-liter Hemi V8. The V6 eTorque powertrain makes 305 horsepower and 269 pound-feet of torque (Ram) or 285 horsepower and 260 pound-feet (Wrangler). The Wrangler's four-cylinder eTorque is good for 270 horses and 295 lb-ft. The V8 version in the Ram is good for 395 horsepower and 410 lb-ft of torque. In all cases, the eTorque system does not increase peak output over the standard version of the gasoline engine. The mild-hybrid system does provide a minor fuel-economy boost. In the Wrangler, the 3.6-liter with eTorque has EPA city estimates that are 1 mpg better than without the system. On the Ram's V8, eTorque adds 2 mpg city and 1 mpg highway. (The 2.0-liter sees no improvement in its EPA ratings.) It's not known whether the Durango will add eTorque to its V6, or V8, or both. Either engine could do with a fuel-economy boost, as the V6 is EPA rated at 19/26 mpg city/highway (RWD) and 18/25 mpg (AWD), while the V8 version has estimates of 14/22 mpg. Related Video:

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.
