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.

Major automakers urge Trump not to freeze fuel economy targets

WASHINGTON — Major automakers are telling the Trump administration they want to reach an agreement with California to avoid a legal battle over fuel efficiency standards, and they support continued increases in mileage standards through 2025. "We support standards that increase year over year that also are consistent with marketplace realities," Mitch Bainwol, chief executive of the Alliance of Automobile Manufacturers, a trade group representing major automakers, will tell a U.S. House of Representatives panel on Tuesday, according to written testimony released on Monday. The Trump administration is weighing how to revise fuel economy standards through at least the 2025 model year, and one option is to propose freezing the standards through 2026, effectively allowing automakers to delay investments in technology to cut greenhouse gas emissions from burning petroleum. The National Highway Traffic Safety Administration has not formally submitted its joint proposal with the Environmental Protection Agency to the White House Office of Management and Budget for review. Even so, last week, California and 16 other states sued to challenge the Trump administration's decision to revise U.S. vehicle rules. Auto industry executives have held meetings with the Trump administration for months and have urged the administration to try to reach a deal with California even as they support slowing the pace of reduction in carbon dioxide emissions that the Obama administration rules outlined. One automaker official said part of the message to President Donald Trump at a meeting on Friday will be to consider California like a foreign trade deal that needs to be renegotiated. Automakers want to urge him to get automakers a "better deal" — as opposed to potentially years of litigation between major states and federal regulators. On Friday, Trump is set to meet with the chief executives of General Motors, Ford, Fiat Chrysler and the top U.S. executives of at least five other major automakers, including Toyota, Volkswagen AG and Daimler AG, to talk about revisions to the vehicle rules. Senior EPA and Transportation Department officials will also attend. Environmental groups are eager to keep the rules in place, saying they will save consumers billions in fuel costs. A coalition of groups plans to stage a protest outside Ford's headquarters in Michigan.

VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.
