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.

Peugeot will prove it doesn't offer cheater diesels

Our diesels are clean, really. That's the message from French automaker PSA/Peugeot-Citroen as it plans to go on the offensive in response to Volkswagen's diesel-emissions scandal. PSA will go out of its way to prove its diesels are as clean as advertised. The company is looking at disclosing "real-world" fuel-economy statistics as soon as next spring and will use an independent entity to vet the numbers, Automotive News Europe says, citing comments that PSA/Peugeot-Citroen financial chief Jean-Baptiste de Chatillon made to reporters this week. Such efforts may be vital, since roughly two-thirds of the vehicles Peugeot-Citroen sells in Europe are powered by a diesel engine. Last month, VW admitted that as many as 11 million of its diesel-powered vehicles were programmed with software designed to cheat emissions-testing systems. The news shook up the industry, especially companies that sell a good chunk of diesels. The EU itself may start instituting "real world" fuel-economy and emissions testing as soon as 2017. French regulators have said they may eliminate diesel-fuel subsidies that currently make diesel fuel cheaper to customers than gas. That adjustment may occur as soon as next year, since it's been pushed up in response to the VW scandal. Peugeot-Citron continues to reiterate that it has never installed software that was designed to cheat emissions-testing systems. Additionally, the automaker was more than a decade ahead of European Union mandates for engine components designed to cut soot emissions, so the company is hoping its track record makes a difference. It wants to be perfectly clear about that.

VW offers to buy back new diesels if bans introduced

By Maria Sheahan FRANKFURT, Germany — Volkswagen will buy back new diesel cars if German cities ban them, it said on Thursday, seeking to reassure potential buyers and stem a plunge in sales of diesel vehicles. Europe's biggest automaker also said it would extend incentives for buyers of new diesel cars. The moves come after a German court ruled last month that cities in the country could ban the most polluting diesel vehicles from their streets. Many German cities exceed European Union limits on atmospheric nitrogen oxide, known to cause respiratory diseases. Fears of bans have led to a plunge in demand for diesel vehicles, which are also key to carmakers' attempts to meet new EU rules on carbon dioxide (CO2) emissions. While diesel cars are heavily criticized for emitting nitrogen oxide, they spew out less CO2 than gasoline equivalents. Diesel car sales plunged 19 percent in Germany last month. At its core VW brand, Volkswagen said its buyback offer applied to new diesels bought between April 1 and the end of 2018 and would kick in if the city in which the buyer lived or worked banned diesels within three years of the purchase. It said its dealerships would buy back diesel vehicles affected by bans at their current value if their owners at the same time bought a new vehicle that was not affected by cities' driving restrictions. At Czech brand Skoda, the guarantee applies to cars bought between April 1 and the end of June, but will cover bans introduced within four years of the purchase date. At premium brand Audi, the offer only covers leased vehicles. Volkswagen also said it was extending to the end of June incentives for customers trading in older diesels for new ones. Fellow German carmaker BMW said earlier this month it would offer to take back leased vehicles if diesels were banned within 100 kilometers (62 miles) of the operator's home or place of work. There has been a global backlash against diesel-engine cars since Volkswagen admitted in 2015 to cheating U.S. exhaust tests. But Germany's government is seeking to avoid widespread bans on heavily polluting diesel vehicles, which companies say could cut the resale value of up to 15 million vehicles in Europe's biggest car market. In Germany, where motorists expect to drive powerful cars on motorways with no speed limits, any restrictions will be unpopular.
