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.

Least satisfying vehicle rankings seek to highlight the worst cars of the year

Consumer Reports polls its members on all sorts of topics related to how they buy and use products ranging from mobile phones to humidifiers for indoor plants. Cars are regularly one of CR’s most interesting topics, and its recent study on the least satisfying vehicles to own offers insights into the cars people wish they hadnÂ’t purchased. CR polled thousands of members with questions about what they liked and disliked about the vehicle theyÂ’d owned for a few years. When asked if they would definitely repurchase the same car, the following vehicles came back as the least likely to be purchased a second time: Kia Forte: 51% would buy again Nissan Altima: 51% would buy again Nissan Kicks: 49% would buy again Volkswagen Taos: 48% would buy again Kia Seltos: 48% would buy again Jeep Compass: 46% would buy again Mercedes-Benz GLA: 45% would buy again Infiniti QX50: 40% would buy again Mercedes-Benz GLB: 39% would buy again Volkswagen Atlas Cross Sport: 38% would buy again When Autoblog tested the VW Atlas Cross Sport in March 2022, we liked the styling and the price was right, but it lagged rivals in driving excitement and interior quality. A number of recalls donÂ’t help the Cross SportÂ’s cause much, either, as some models have more than a dozen actions by the National Highway Traffic Safety Administration. Even the 2023 model already has four recalls. The annoyance of recalls and the hassle of just-average reliability ratings could have played into the Cross SportÂ’s place as the least satisfying vehicle. On the other end of the spectrum, the Chevrolet Corvette earned the top spot as CR's most satisfying car. The Porsche 911, Rivian R1T, Ford Maverick Hybrid, and Hyundai Ioniq 5 round out the top-five most satisfying vehicles to own. Given the rabid following the 911 has built over the years and the insane performance Chevy derived from the latest Corvette, itÂ’s not surprising to see them in the top spots.

Volkswagen loses thousands of vehicles in Chinese explosion

Yesterday, a blazing, explosive fireball erupted from a port in the city of Tianjin, in China, lighting up the night sky and shattering windows with the force of 21 tons of TNT. Hundreds were injured and the death toll continues to rise, with the most recent reports claiming 50 were killed. While the human cost of this tragedy simply can't be overstated, it hasn't taken long for corporations to look into what the enormous explosion cost them. And for Volkswagen, the answer is quite a lot. According to our friends at Jalopnik, a Chinese source claims the German giant, which remains one of the PRC's most popular brands, lost thousands of vehicles. The automotive casualty sheet lists 1,065 Touaregs, 391 Beetles, 257 Tiguans, 114 Golfs, 84 Up! minicars, 39 SportVans, and 28 Magotans (a locally built version of the Passat). While those are the only vehicles listed, the Chinese source said over 2,700 vehicles were destroyed. For example, both Land Rover and Renault lost an unspecified number of Discovery SUVs and Koleos CUVs, respectively. The explosion also affected Toyota. Its research and design facility with joint-venture partner Sichuan FAW also suffered an unspecified amount of damage. You can check out the translated source article here. As Google Translate jobs go, though, this one is particularly bad, but it still offers some details of the automotive cost of this disaster.
