Japanese automakers will seriously subsidize hydrogen fuel stations

Fresh off the announcement of the EPA-rated fuel economy and range figures for the Toyota Mirai, three of Japan's major automakers are throwing their weight behind hydrogen on the other side of the Pacific. Toyota, Nissan, and Honda are detailing their partnership in Japan to subsidize the creation of an expanded FCV refueling infrastructure there in the coming years. The plan could provide a much-needed boost for goals that are already looking to miss their targets. The partnership, which is called the Joint Hydrogen Infrastructure Support Project, is subsidizing a third of the annual operating expenses up to a maximum of 11 million yen ($90,000) for any hydrogen refueling station that applies and is accepted into the program. For now, the automakers plan to keep this running through around 2020. Toyota senior managing officer Kiyotaka Ise tells Bloomberg the whole thing over that time is expected to cost 5 billion to 6 billion yen ($40.5 million to $49 million). In addition to the money, the companies are trying to raise awareness about the alternative fuel to build popularity. Japan has been pushing extremely hard to build the FCV market there for quite some time by subsidizing both the models and building refueling stations for them. By the 2020 Olympics, the country's goal is to have 6,000 fuel cell vehicles on the roads and possibly even 100,000 of them by 2025. The cars to fulfill these lofty hopes are just gaining steam, though. For example, the Mirai is already experiencing high demand, and Honda is set to bring its new challenger in 2016. This announcement says Nissan is aiming a potential entry for 2017, as well. According to Bloomberg, the fuel cell industry in Japan is forecasted to balloon from 400 million yen (3.3 million) in the current fiscal year to 100 billion ($813 million) by 2025. Toyota, Nissan, and Honda Agree on Details of Joint Support for Hydrogen Infrastructure Development Toyota Motor Corporation, Nissan Motor Co., Ltd., and Honda Motor Co., Ltd. have agreed on key details regarding a new joint support project for the development of hydrogen station infrastructure in Japan. In addition to partially covering the operating costs of hydrogen stations, the three automakers have also agreed to help infrastructure companies deliver the best possible customer service and create a convenient, hassle-free refueling network for owners of fuel cell vehicles (FCVs).

Toyota engineer warns automous cars could increase fuel use, urban sprawl

An increasing number of people are starting to consider the potential downsides of a transition to autonomous cars. The FBI is already looking at them for the potential ill effects on law enforcement, and a scientist for Toyota is raising the possibility that driverless vehicles could actually be detrimental to the environment over the long term.
Ken Laberteaux, who studies future transportation for Toyota, thinks that autonomous cars could lead to more pollution, not less, says Bloomberg. However, Laberteaux's theory isn't so much based purely on science as it is considering behavioral and historical trends. "US history shows that anytime you make driving easier, there seems to be this inexhaustible desire to live further from things," said Laberteaux during a presentation at the Automated Vehicles Symposium in San Francisco, CA, cited by Bloomberg.
Laberteaux's belief is that if commuters can make their drives easier, then they will be more willing to live farther away from the cities where they work. The end result would be more urban sprawl and increased pollution from the longer travel times.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
