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.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

Renault to name VW manager Luca De Meo as CEO

PARIS — Renault's board is set to meet later on Tuesday to approve the nomination of Luca de Meo, the former head of Volkswagen's Seat brand, as its next chief executive, two sources familiar with the matter said. The Italian-born executive, who stepped down from Seat earlier this month, is not due to take up his post at the French carmaker until towards July, due to negotiations around his contract, according to one of the sources. Renault declined to comment. De Meo is not expected to face any last minute hurdles in his nomination, and has already won tacit backing from parties including the French government, a Renault shareholder. His appointment fills one of the major gaps left at the firm as it tries to move past a year of turmoil following the 2018 arrest in Tokyo of former boss-turned-fugitive Carlos Ghosn, and reset its strained alliance with Japan's Nissan. Ghosn, who forged and oversaw the Renault-Nissan partnership for almost two decades, has since fled Japan and resettled in Lebanon, from where he has contested the financial misconduct charges against him and said the alliance was at risk of collapse. De Meo, along with Renault Chairman Jean-Dominique Senard, brought in last January from tire maker Michelin, will have his work cut out to turn around the firm. Like rivals, Renault is grappling with a downturn in demand, and has said it expects a slight decline in the car market in Europe, Russia and China this year. The firm has also presented 2020 as a make-or-break year for the alliance with Nissan and is under pressure to deliver on cost savings and joint projects. Automakers face pressure to meet stringent new emissions targets with less polluting models, and are also competing to produce innovations such as self-driving cars, which require large investments. De Meo, who speaks French, will be one of a growing handful of outsiders in senior company jobs in France. The 52-year-old started his career at Renault and has worked at Fiat and Audi among other brands. He is credited with revitalizing sales at Barcelona-based Seat, imbuing it with a more sporty image, though his portfolio will be markedly larger at Renault, whose brands include Dacia and Lada. Renault's finance chief Clotilde Delbos has been CEO on an interim basis since last October, when Thierry Bollore, a former Ghosn ally, was ousted by the board.
