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.

MotorWeek revisits the awesome, original Dodge Viper

MotorWeek is bringing the automotive world a wonderful blast from the past with its latest Retro Review. Not only does the video feature the now-famous, original Dodge Viper, but this is also a chance to watch one lapping Pocono International Raceway in a test of track prowess. This segment was MotorWeek's first chance to unleash the Viper around a racecourse, and the show took advantage of the opportunity. In addition to the usual 0-60 mph and quarter-mile tests, the 400-horsepower V10 is let loose to do lap after lap. The clip offers a great dose of nostalgia and is worth a watch to remember the intense enthusiasm surrounding the Viper at the time.

Armormax loads a bulletproof Dodge Hellcat AWD Police Special

Earlier, we wrote about the Armormax armored Tesla Model S P100D, which International Armoring Corporation called the fastest armored car in the world. As the company also outfits cars such as Dodge Chargers, it's only logical that the showcase car is a SRT Hellcat — but the interesting thing is that the company can also upgrade the Hellcat to all-wheel drive, as Armormax told Motor Authority. When ordering an armored Charger SRT Hellcat, the AWD implementation is just a matter of ticking the corresponding box. The Armormax Charger SRT Hellcat seen here is also outfitted with police patrol car gear, complete with a push bar, run-flat tires, ballistic bulletproof glass and a mean matte black wrap. Even if the 6.2-liter, supercharged Hellcat powertrain probably has no problem hauling an armored bodyshell around, it's likely that the company has used the same synthetic fiber laminate on the Charger as on the Tesla. The bulletproof Tesla's weight gain was a negligible 11 percent, and while the Charger is a lighter car to begin with, avoiding using regular-issue ballistic steel seems to be the way to go if you want to keep the curb weight in check. The Hellcat's battery, radiator, fuel tank and ECU also get their share of protective covering, so that the vehicle is harder to disable. Paneling is available in ballistic protection levels ranging from B4 (can withstand a .30-caliber lead-core softpoint bullet) to B7 (can withstand a 9mm full-copper jacket). And while pricing isn't announced, it is likely to depend on how much protection is applied on the Hellcat and whether all four wheels are powered. A stock one is priced at $65,345. Related Video:
