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.

McLaren, Red Bull and Ferrari call for unfreezing F1 engines

Formula One is a hugely expensive sport. Not only do you have enormous salaries and logistical expenses, as you would in any other sport, but each team also spends huge sums developing their own chassis from the ground up – and so too do the participating automakers in developing the engines. One of the ways the series organizers mitigate those costs is by freezing development. So once the new crop of V6 turbo hybrid powertrains were developed, that was it. But now three of the of the sport's leading teams are calling on the FIA to unfreeze engine development. Their reason? Unfair advantage. There's little question that Mercedes did the best job of developing its "power unit" to meet the new regulations that took effect at the beginning of this past season. That's how the Mercedes team won all but three of the grands prix this season and finished with at least one car on the podium at every single race. It's also a big part of how the teams that bought their engines from Mercedes this season managed to consistently outperform the other non-works-supported teams. That clear advantage is why Red Bull, Ferrari and now McLaren are calling for engine development to be unfrozen. Their argument is that, under the current locked-down status quo, their engine suppliers (Renault, Ferrari and Honda, respectively) cannot possibly catch up. So unless the FIA and Formula One Management want the next few seasons to be the kind of absolute blow-outs that this past season was, these leading teams argue, the powers that be are going to have to make some changes. For its part, Mercedes naturally counters that unfreezing engine development would send costs spiraling out of control. But then of course it stands to lose the most by re-opening engine development. If those three teams, however, closely intertwined as they are with the three other engine suppliers participating in next year's championship, manage to solicit enough support from the other customer teams and bring the matter to a vote, Mercedes may very well find itself out-numbered.

Drive like a prince: Join us for a walk through Monaco's car collection

Small, crowded, and a royal pain in the trunk lid to drive into during rush hour, Monaco sounds like an improbable location for a huge car museum. And yet, this tiny city-state has been closely linked to car culture for over a century. It hosts two major racing events every year, many of its residents would qualify for a frequent shopper card if Rolls-Royce issued one, and Prince Rainier III began assembling a collection of cars in the late 1950s. He opened his collection to the public in 1993 and the museum quickly turned into a popular tourist attraction. The collection continued to grow after his death in April 2005; it moved to a new facility located right on Hercules Port in July 2022. Monaco being Monaco, you'd expect to walk into a room full of the latest, shiniest, and most powerful supercars ever to shred a tire. That's not the case: while there is no shortage of high-horsepower machines, the first cars you see after paying ˆ10 (approximately $11) to get in are pre-war models. In that era, the template for the car as we know it in 2023 hadn't been created, so an eclectic assortment of expensive and dauntingly experimental machines roamed whatever roads were available to them. One is the Leyat Helica, which was built in France in 1921 with a 1.2-liter air-cooled flat-twin sourced from the world of aviation. Fittingly, the two-cylinder spun a massive, plane-like propeller. Government vehicles get a special spot in the museum. They range from a Cadillac Series 6700 with an amusing blend of period-correct French-market yellow headlights and massive fins to a 2011 Lexus LS 600h with a custom-made transparent roof panel that was built by Belgian coachbuilder Carat Duchatelet for Prince Albert II's wedding. Here's where it all gets a little weird: you've got a 1952 Austin FX3, a Ghia-bodied 1959 Fiat 500 Jolly, a 1960 BMW Isetta, and a 1971 Lotus Seven. That has to be someone's idea of a perfect four-car garage.  One of the most significant cars in the collection lurks in the far corner of the main hall, which is located a level below the entrance. At first glance, it's a kitted-out Renault 4CV with auxiliary lights, a racing number on the front end, and a period-correct registration number issued in the Bouches-du-Rhone department of France. It doesn't look all that different than the later, unmodified 4CV parked right next to it. Here's what's special about it: this is one of the small handful of Type 1063 models built by Renault for competition.
