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.

Mercedes completes production of G63 AMG 6x6

Considering its 19-foot length, it sure was short-lived. A flash in the pan, really, in so far as a 4-ton beast could possibly be. But the Mercedes G63 AMG 6x6 is reportedly wrapping up its short production run this month. Based on a military variant of the legendary Gelandewagen but built for civilian consumption, the G63 AMG was – and will likely forever remain – the ultimate version of Benz's ultimate off-roader. It features six driven wheels on three axles with five differentials, all powered by AMG's stalwart 5.5-liter twin-turbo V8. Mercedes rolled out the 6x6 on all its half-dozen driven wheels barely over a year ago, and despite its half-million-dollar sticker price, demand soared. But after selling about 100 of them, the German automaker is putting it to pasture, ensuring its rarity in the annals of off-roader history. In its place, Benz will now begin production of the (relatively and slightly) less bonkers G500 4x42, which employs a tamer 4.0-liter twin-turbo V8 driving a more conventional four wheels, and ditches the pickup short-bed for an enclosed wagon body-style, but keeps its eccentric big brother's jacked-up ride height. Those looking for the last word in power, though, will be more interested in the twelve-cylinder G65 that will now be coming to US dealers with a $200k+ sticker price. Related Video:

2021 Mercedes-Maybach S 580 revealed as the biggest, most luxurious S-Class

The Mercedes-Maybach GLS-Class made a splash recently as the company's ultra-luxury crossover. But if you're a well-heeled individual looking for the true peak of Mercedes luxury, there's no replacement for the 2021 Mercedes-Maybach S 580, the biggest, fanciest sedan the company can produce. You'll be able to identify the land yacht thanks to a number of styling tweaks. The grille gets slender vertical chrome bars, and the lower intakes feature a chrome mesh. Topping the grille is a Mercedes hood ornament. The hood is restyled, too, with a center ridge running front to back with a line of chrome trim. Besides these styling tweaks, the Mercedes-Maybach has had its wheelbase stretched a full seven inches, with the space going to rear passenger room. The stretch also included rear quarter windows. Just behind those windows are illuminated Mercedes-Maybach badges. The car can also be optioned with an array of exclusive wheels and two-tone paint. The two-tone paint jobs can take up to a week to complete. Of course, the interior is what really sets the Mercedes-Maybach apart from the "average" S-Class. All examples come standard with Mercedes Designo leather upholstery, and even the headliner is finished in leather. Like other S-Class models, there is an air freshener function, and Mercedes has saved a special scent specific to the Maybach. The front seat backs are covered in wood trim to enhance the design. Rear occupants get individual 11.6-inch screens for entertainment, as well as a removable tablet for controlling various car functions. Passengers get to enjoy a 1,750-watt, 30-speaker Burmester sound system, which won't be interrupted by outside noises thanks to additional sound deadening materials around the rear arches, thicker laminated quarter windows and active noise cancelling. Foam-filled tires and laminated glass around the rest of the car are options. Speaking of options, there aren't many, but they're also quite lavish. The one we expect to be quite popular is the executive rear seating. It replaces the rear bench with two reclining chairs complete with power leg rests. These leg rests even feature massage functions, a first for the S-Class. The seats come with climate adjustments and several massage settings. The option also adds seatbelt airbags and frontal airbags for the rear passengers. Other interior options include a refrigerator, champagne flutes and electrically assisted rear doors for easier entry and exit.
