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 G 500 4x4 is mighty mean and bright lime green

The Mercedes-Benz G500 4x42, finally ready to meet the crowds at the Geneva Motor Show, might just be the best factory-prepped expedition off-roader on the market, should Mercedes choose to build it. The short story is that some well-heeled admirers of the G63 AMG 6x6 said, "It's nice, but can you take it down a notch?" And by "notch" they meant "an axle." So the G500 4x42 gets just two portal axles instead of three, and a slew of other features. The 4x4 squared offers up a standard G-wagen body, but instead of the 5.5-liter twin-turbo V8 from the G63, there's a new 4.0-liter twin-turbo V8 with 422 horsepower and 450 pound-feet of torque. Compared to the standard G500, the track is 11.8 inches wider, the street-cred rims being 22-inchers on 325/55 R-series tires. When it's time to get dirty, they can be swapped for an optional set of 18-inch wheels with 37-inch beadlock tires. With that setup and the same wheelbase as the G500 LWB, ground clearance and fording depth are more than doubled to 17.7 inches and 39 inches respectively, the angle of approach goes from 36 degrees to 52 degrees and the angle of departure leaps from 27 degrees to 54 degrees. Breakover angle is bumped from 21 degrees to 47 degrees, a two-piece stainless steel undertray protecting the sensitive bits when you push it. The only parts that get a raised eyebrow are the carbon fiber wheel arches and bumpers, which might behave badly when they meet an immovable granite object. To escape the sensation of driving the Taj Mahal in urban environments, there's a twin spring-and-damper setup at each wheel. One of the spring-damper combos is electronically controlled and adjustable, and when called into action via the Comfort or Sport mode, takes control of wheel action; even when passive, it will kick in to automatically to stiffen the body if it detects evasive maneuvers. On top of all that, to remind you that you're in a Mercedes the interior is fitted out with Designo leather trim and diamond-quilted microfiber. Mercedes is going to gauge its Geneva reception before deciding to build it, a hurdle we're sure will be overcome. Car and Driver drove it and verified it's the real deal, with pricing - if it's built - speculated to land between the G63 AMG and G65 AMG. The press release below has all the details.

Mercedes-Maybach SL 680 Monogram Series gives the rich and famous what they want

TOPANGA, Calif. – Give the people what they want, right? Especially if they're extremely wealthy. And possibly famous.  Apparently, the requests for a convertible Maybach from existing owners and/or celebrities were so frequent and insistent that the uber-luxury offshoot of Mercedes-Benz finally decided to give them just that. The 2025 Mercedes-Maybach SL 680 Monogram Series answers the call. While all other Maybachs are based on a Mercedes-Benz, this is the first Maybach to be based on a car developed by AMG: the current-generation SL 55 and SL 63. This presented a greater challenge to engineers than past efforts. Although a sportier Maybach was intended (as opposed to modern Maybach's first drop-top effort, the Maybach S 650 Cabriolet), the SL 680 is, not surprisingly, seeking a much different dynamic end goal than its AMG-only cousins. According to Maybach product manager Hannes Meyer, the far shorter wheelbase than the Maybach norm was a particular challenge in making sure that its convertible offering maintained "the same ease and nearly floating driving experience" expected of the brand. To that end, the Maybach SL shares the SL 63's air suspension and trick AMG Active Control interconnected hydraulically controlled dampers, but the tuning is changed, especially with the rear air springs as the driver sits closer to those. Meyer says the damper valves in particular have a greater range between sportiness and comfort than the SL 63. The steering system is totally Maybach-specific, including a different ratio and more upright front camber, resulting in what Meyer described as a more stable and less aggressive setup than what you'd find in the SL 63.  Before you start looking for a 6.8-liter engine in the Mercedes arsenal, remember that those numbers don't really mean anything anymore. The Maybach SL 680 has exactly the same 4.0-liter twin-turbo V8 as the SL 63 good for 577 horsepower and 590 pound-feet of torque. The nine-speed AMG transmission is the same in terms of hardware, but it has totally different software. In particular, the 2-3 and 3-4 shifts are most different in order to provide a smoother, more Maybach acceleration experience. The 4Matic+ all-wheel-drive system is also shared, but is programmed to have a more balanced front-to-rear power split than the rear-biased AMG. Finally, the exhaust has been retuned. Meyer said that up to 2,800 rpm, the exhaust isn't quieter than what you'd experience in the AMGs, it just has a different tone.
