Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.

Skoda plans big investment into electric cars as part of rebound effort

PRAGUE — Czech carmaker Skoda, part of the Volkswagen Group, said on Wednesday it would invest around 2.5 billion euros over the next five years on future technologies, with more than half going to electric vehicle investment. The Czech Republic's largest exporter is hoping for a rebound in 2021 from a global car sales drop but faces uncertainty over the coronavirus pandemic and a semiconductor shortage rattling the industry. "This year is likely to be another big challenge," finance director Klaus-Dieter Schuermann said. "We expect Skoda Auto's group performance to improve, with sales revenue significantly above the level of last year." Skoda reported on Wednesday a 54.5% drop in 2020 operating to 756 million euros ($894 million). Sales revenue dropped 13.8% to 17.1 billion euros. Global deliveries remained above 1 million cars for a seventh straight year despite a 19% drop after production outages at the outset of the pandemic and a fall in China, its biggest single market. Chief Executive Thomas Shaefer said the car company was managing the semiconductor shortage "but it will follow us for awhile" and the impact was not visible yet. Skoda's core market in Europe would be electric in the future, Shaefer said, although it was still not time to completely switch away from traditional models, which include the launch last year of a new generation of its flagship Octavia model. It has also started production of the all-electric Enyaq iV model, which is a version of Volkswagen's ID.4. Skoda plans investments of 1.4 billion euros into electromobility development as part of its five-year investment plan. Investments will also go into digitalization activities and plant modernization. Related video: Green Volkswagen Skoda Electric

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.
