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.

Our love of SUVs is killing people in the streets

Americans are fond of supersized fast-food meals and colossal convenience-store fountain drinks, even though they're clearly bad for our health and U.S. adults keep getting fatter. We also like large vehicles, and our love affair with SUVs is killing people in the streets. According to a recent investigation by the Detroit Free Press/USA Today, the increase in SUV sales over the past several years coincides with a sharp rise in pedestrian deaths in the U.S. — up 46 percent since 2009, with nearly 6,000 people killed in 2016 alone. With SUV sales surpassing sedans in 2014 and pickups and SUVs currently accounting for 60 percent of new vehicle sales, it's no wonder Ford announced in April plans to cease U.S. sales of almost all passenger cars. And this followed Fiat Chrysler's move to virtually an all-truck, -SUV and -crossover lineup. While the Freep/USA Today investigation found that the simultaneous surge in SUV sales and pedestrian deaths comes down to vehicle size, it also points to a lack of action on the part of the National Highway Traffic Safety Administration (NHTSA), even though it knew of the dangers SUVs pose to pedestrians. Also blamed are automakers dragging their feet on implementing active safety features. Using federal accident data, the Insurance Institute for Highway Safety (IIHS) determined that there was an 81 percent increase in single-vehicle pedestrian fatalities involving SUVs between 2009 and 2016. Freep/USA Today's analysis of the same data by counting vehicles that struck and killed pedestrians instead of the number of people killed showed a 69 percent increase in SUV involvement. As far back as 2001, researchers at Rowan University forecasted a rise in pedestrian deaths as Americans began switching to SUVs. "In the United States, passenger vehicles are shifting from a fleet populated primarily by cars to a fleet dominated by light trucks and vans," the researchers wrote, with light trucks comprising SUVs.

Mercedes chief invites Audi, BMW to compete in F1

Mercedes-Benz didn't just win the Formula One World Championship in 2014 – it positively dominated it. The team won all but three of the grands prix this season, scoring a one-two finish at more than half of them and landing at least one car on the podium at every race without exception. It goes without saying, then, that the German automaker thrives on competition, but now it's welcoming even more. Speaking with Germany's Sport Bild at its homecoming celebration in Stuttgart, Daimler chief Dieter Zetsche welcomed Mercedes' biggest rivals Audi and BMW to join it on the F1 grid. Noting that the three German brands share some 80 percent of the market for luxury automobiles, Zetsche said that F1 would make a natural arena of competition for Mercedes, Audi and BMW to fight for top bragging rights. The three currently compete against each other in front of home audiences in the DTM touring car series – effectively Germany's equivalent to NASCAR – but of the ten races held this year, the majority were in Germany itself, and all of them took place in Europe. BMW last competed in F1 when it bought the Sauber team in 2006, but withdrew from the series in 2009. Despite its progenitor Auto Union having fielded the famous Silver Arrows in pre-war grand prix racing, Audi has never been a player in modern F1 racing, though recent rumors have linked it to a potential foray – spurred by the arrival of sister-company Porsche on its home turf at Le Mans, the departure of several of its key endurance drivers and the hiring of former Scuderia Ferrari chief Stefano Domenicali. Porsche had similarly considered an F1 program before getting the go-ahead to compete with Audi at Le Mans. As for the prospect of Mercedes competing in other international racing series, Zetsche added that year-long preparations for 24 hours of racing at Le Mans didn't present a good cost-benefit ratio in his estimation, but that Formula E (where Audi currently supports a quasi-works entry) would be worth a closer look.
