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.

French probe alleges 2 million PSA cars had engine cheats

PARIS — A French investigation into alleged emissions cheating by PSA Group found that suspect software had been used on almost 2 million vehicles sold by the maker of Peugeot and Citroen cars, Le Monde reported on Friday. Paris-based PSA denies any use of fraudulent engine software, a spokesman said in response to the newspaper report, which sent PSA shares sharply lower. The stock was down 4.4 percent at 17.78 euros as of 1019 GMT. So-called "defeat devices" restrict exhaust output of toxic nitrogen oxides (NOx) under regulatory test conditions while letting emissions far exceed legal limits in real-world driving. In February, PSA became the fourth carmaker to be referred to French prosecutors by the country's DGCCRF watchdog over suspected emissions test-cheating, after Volkswagen, Renault and Fiat Chrysler. PSA's engineering chief acknowledged at the time that emissions treatment in the group's diesels was deliberately reduced at higher temperatures to improve fuel efficiency and carbon dioxide (CO2) emissions in out-of-town driving, where NOx output is considered less critical. According to Le Monde, an internal PSA document obtained by DGCCRF investigators includes discussion of the need to "make the 'defeat device' aspect less obvious and visible." However PSA insists there is nothing fraudulent or illegal about its engine calibrations. "PSA denies any fraud and firmly reaffirms the pertinence of its technology decisions," the company said on Friday.

Volkswagen says goodbye to Eos, Routan in 2015 updates

Usually automakers announce changes to their lineup individually on a vehicle-by-vehicle basis, but sometimes it all comes at once – especially when the changes are ones we either expected or might not otherwise notice. That's the path Volkswagen has gone with changes to its US lineup for 2015. The biggest change is what we already knew: that the new Golf arrives for the 2015 model year, bringing with it the new GTI, Golf R, e-Golf and Golf SportWagen (to replace the previous Jetta wagon). But there are some new details as well. For starters, Volkswagen has finally confirmed that both the Eos and the Routan – both long rumored to be on their way out – will be exiting this year. The Eos hardtop convertible, pictured above, will linger for one last year, its Sport trim replaced by a new Final Edition with 18-inch wheels, two-tone leather interior and enhanced equipment. Meanwhile the Routan, which hasn't actually been built in over a year, is finally dead, as VW confirms it has dropped the Chrysler-built minivan from its lineup for 2015 altogether. The German automaker has also confirmed that the Touareg is getting a facelift early in the new year, which we expect will closely follow the revisions revealed a few months ago ahead of the Beijing Motor Show. Finally VW has announced an upgrade to its 2.0-liter TDI. Fitted to the Golf, Jetta, Passat and Beetle, the updated diesel gets 10 more horsepower with output now up to 150 hp and 236 pound-feet of torque. Scope out the full list of announcements in the press release below. MODEL YEAR 2015: NEW GOLF FAMILY, REDESIGNED JETTA, AND NEW TDI® CLEAN DIESEL ENGINE HEAD THE CHANGES Jul 22, 2014 In a busy year, Volkswagen will also add a new Golf SportWagen, an all-new Golf R, a redesigned Touareg SUV, and the company's first U.S.-market EV, the e-Golf - All-new Golf is bigger, lighter, and more fuel-efficient than the previous model, seats five, and has a larger trunk than any midsize sedan - New Golf GTI has 210-horsepower engine, with improved fuel efficiency and performance - e-Golf is Volkswagen's first full Battery Electric Vehicle for sale in the U.S.
