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.

2016 Canadian Grand Prix: A tale of 3 starts and 2 stops

The first curve in the Canadian Formula 1 Grand Prix happened before Turn 1. Lewis Hamilton sat on pole in the Mercedes-AMG Petronas, Sebastian Vettel in a Ferrari behind. That order changed as soon as the lights went out. Hamilton and teammate Nico Rosberg started well enough, but Vettel flew off the line, passing Hamilton in just a few meters. Vettel led through Turn 1 while Hamilton defended against Rosberg trying to pass on the outside by using the entire track. Hamilton bumped his teammate, sending Rosberg into the concrete runoff with an " infuriating but fair" maneuver Hamilton blamed on understeer. The Brit stayed second, his teammate fell to ninth by the time he rejoined the circuit and got back on the gas. The Ferrari finally looked an even match for the Mercedes, Vettel slowly building a gap out front. On Lap 11 the Honda in Jenson Button's McLaren self-ignited just after the hairpin, forcing Button to pull over on the Casino Straight. A Virtual Safety Car slowed the field, convincing Ferrari to pit its drivers. Vettel came in, handing the lead to Hamilton. The marshals cleared Button's car more quickly than expected, so the scuderia didn't get the full time advantage it expected, sending Vettel back on track seven seconds behind the Mercedes. Button's and Ferrari's unplanned stops decided the race. Ferrari had always planned to run a two-stopper, but the early pit didn't give the team a chance to gauge the ultra-soft Pirelli. The ultra-softs lasted longer than anyone expected. Hamilton only pitted once, Vettel had to pit again, and the Ferrari simply couldn't close the gap to the Mercedes even with newer tires. Post-race commentary accused Ferrari of two blunders: giving up track position, and not taking advantage of Mercedes' only known weakness of not being nearly as good in dirty air. If the ultra-softs had fallen off a performance cliff, however, Ferrari's play would have been considered daring and brilliant. Hamilton took his second win of the season, followed by a hard-driving Vettel five seconds later. Valtteri Bottas and Williams got everything right, the Finn taking advantage of a one-stop strategy, a perfectly-timed pit stop, and more unusual Red Bull issues to finish third. It's Williams' first podium of the year. Max Verstappen claimed fourth after two pit stops, holding off a frustrated Rosberg who had to make an unscheduled stop to remedy a slow puncture.

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.
