The real reason automakers are giving away free hydrogen

Just like Hyundai did with its Tucson fuel cell, Toyota is offering free hydrogen fuel with the $57,500 Mirai H2 sedan. Toyota is being a bit vague about the details, saying simply that Mirai drivers will get, "complimentary hydrogen fuel for up to three years." Turns out, the reason that the hydrogen avant-garde will not be paying anything at the pump isn't because the automakers want to give them a boost or because the OEMs are kind. Instead, it's simply impossible to accurately charge people for hydrogen right now. It's simply impossible to accurately charge people for hydrogen right now. At an in-depth hydrogen seminar this week as part of the Mirai preview, three representatives from various hydrogen organizations revealed that the current hydrogen stations (most of which are in California) are not set up to accurately measure the hydrogen that is dispensed. Without this little bit of information, you can't charge customers for the fuel they use. Toyota is well aware of this, and Toyota Motor Sales' national manager of environmental, safety and quality communications, John Hanson, said that, "There are no set standards, so there is no way to charge people for anything." Alberto Ayala, the deputy executive officer for the California Air Resources Board, said CARB is in the middle of developing a way to sell a given amount of hydrogen, "which up to this point doesn't exist. If you think about it, it's a real simple yet real practical challenge. If you're going to pay for X amount of hydrogen, you're actually getting that amount of hydrogen." Ayala said it's not a difficult technical problem to measure the hydrogen as it goes into the car, but "we just have not done it. We are at a point where we are solving multiple remaining questions [with hydrogen infrastructure], and that just happens to be one of them." The National Institute of Standards and Technology says that there has been a discussion to change the current tolerance of two percent up to 10 or 20 percent, but that new technology should be able to measure accurately to within one percent. Air Liquide is working with Toyota to launch the Mirai in the US and Air Liquide CEO Ole Hofelmann told AutoblogGreen that being able to charge customers will be key to the technology's success. "We need to make sure we accurately measure the gas," he said.

Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

2015 Toyota Camry Hybrid

Toyota offers many flavors of its refreshed 2015 Camry, but those who choose to lower their operating cost-per-mile, squeeze 500-plus miles out of each tank of fuel or run a very efficient and reliable sedan in their taxi fleets will only be interested in one: the Camry Hybrid.
The exterior of the 2015 Camry Hybrid is nearly indistinguishable from its gasoline-only counterparts, with the same all-new sheetmetal and bumpers. The Hybrid is offered in LE, SE and XLE trims, meaning customers are offered base, sport or luxury configurations, respectively.
While Toyota expended quite a bit of effort resculpting and improving the 2015 Camry Hybrid, one area it didn't touch was the powertrain - it is virtually identical to last year's model (just like the gas version). Under the hood is a 2.5-liter Atkinson cycle four-cylinder gasoline engine (156 horsepower and 156 pound-feet of torque) and an electric tractive motor (141 horsepower and 199 pound-feet of torque). Combined, and running through Toyota's unique Hybrid Synergy Drive electronic continuously variable transmission, the two produce 200 horsepower (Toyota does not list a combined torque figure, and we've asked for clarification). A 1.6 kilowatt-hour nickel-metal-hydride battery, packaged behind the rear seats, provides energy storage.
