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.

Rimac is reportedly close to buying Bugatti from the Volkswagen Group

Croatia-based Rimac is finalizing a deal to purchase Bugatti from the Volkswagen Group, according to an unverified report. If the rumor is accurate, the sale would propel Rimac to the top of the automotive industry, guarantee that Bugatti's future is electric, and mark the beginning of Volkswagen's efforts to divest its empire. Executives in Wolfsburg gave the deal the green light in September 2020, according to anonymous sources who spoke to British magazine Car, but the company's supervisory board hasn't approved it yet. Selling the French company isn't as simple as sending company founder Mate Rimac an email with an account number. Insiders explained Volkswagen would likely trade Bugatti and all of its assets for a significant stake in Rimac that would be transferred directly to Porsche, which already owns 15.5% of the brand. Officials hope to increase that figure to about 49%, meaning Bugatti is theoretically worth about 33.5% of Rimac, which was founded in 2009. Bugatti told Autoblog it can't comment on speculation. Mate Rimac gave us a similar answer. Rumors of a Bugatti sale have hovered around the automotive industry for several years, and they've never materialized. In theory, spinning off the brand would be relatively easy because it's not as deeply integrated into the Volkswagen Group as its sister companies. It doesn't share its W16 engine with another carmaker, for example. And yet, Car speculates Lamborghini, SEAT, ItalDesign, Bentley, and Ducati will also be sold in the coming years, leaving Volkswagen with its namesake division, Skoda, Audi, Porsche, Scania, and MAN. Volkswagen is having an estate sale to fund the development of electric, autonomous, and digital technologies. Its downsizing will send ripples through the auto industry. Porsche could move upmarket if it doesn't have to worry about stepping on Lamborghini's toes, for example. Spinoffs are always risky, so some companies may not survive if they're not bolstered by economies of scale. As of writing, there's no word on who will pick up the brands being divested under this scenario. And, keep in mind none of this is official. Volkswagen hasn't commented on the report. We'll update this developing story as more information becomes available.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.
