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.

VW may move production because of Russia's cutoff of natural gas

Volkswagen AG is exploring ways to counter a shortage in natural gas, including shifting production around its network of global facilities, signaling how the energy crisis unleashed by Russia’s invasion of Ukraine threatens to upend EuropeÂ’s industrial landscape. Volkswagen, EuropeÂ’s biggest carmaker, said Thursday that reallocating some of its production was one of the options available in the medium term if gas shortages last much beyond this winter. The company has major factories in Germany, the Czech Republic and Slovakia, which are among European countries most reliant on Russian gas, as well as facilities in southern Europe that source energy from elsewhere. “As mid-term alternatives, we are focusing on greater localization, relocation of manufacturing capacity, or technical alternatives, similar to what is already common practice in the context of challenges related to semiconductor shortages and other recent supply chain disruptions,” Geng Wu, VolkswagenÂ’s head of purchasing, said in a statement.  RussiaÂ’s decision to throttle gas supplies to Europe has raised concerns that Germany might be forced to ration its fuel. Recent news that gas storage levels hit 90% ahead of schedule has soothed fears of acute shortages this winter, but Germany faces a challenge in replenishing depleted reserves next summer without contributions from Russia. Southwestern Europe or coastal zones of northern Europe, both of which have better access to seaborne liquefied natural gas cargoes, could be the beneficiaries of any production shift, a Volkswagen spokesman said by phone. The Volkswagen group already operates car factories in Portugal, Spain and Belgium, countries that host LNG terminals. Labor hurdles To be sure, any major production shift away from EuropeÂ’s biggest economy would face significant hurdles. VW has some 295,000 employees in Germany and worker representatives account for around half the companyÂ’s 20-member supervisory board. Any shift in production would likely involve a limited number of vehicles rather than wholesale factory shutdowns. While gas supplies for VWÂ’s plants are currently secured, the company has identified potential savings at its European sites to cut gas consumption by a “mid-double-digit percentage,” said Michael Heinemann, managing director of VWÂ’s power-plant unit. Still, the carmaker said it was concerned about the effect high gas prices could have on its suppliers.

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.
