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.

Poor headlights cause 40 cars to miss IIHS Top Safety Pick rating

Over the past few months, we've noticed a number of cars and SUVs that have come incredibly close to earning one of the IIHS's highest accolades, the Top Safety Pick rating. They have great crash test scores and solid automatic emergency braking and forward collision warning systems. What trips them up is headlights. That got us wondering, how many vehicles are there that are coming up short because they don't have headlights that meet the organization's criteria for an "Acceptable" or "Good" rating. This is a revision made after 2017, a year in which headlights weren't factored in for this specific award. This is also why why some vehicles, such as the Ford F-150, might have had the award last year, but have lost it for this year. We reached out to someone at IIHS to find out. He responded with the following car models. Depending on how you count, a whopping 40 models crash well enough to receive the rating, but don't get it because their headlights are either "Poor" or "Marginal." We say depending on how you count because the IIHS actual counts truck body styles differently, and the Infiniti Q70 is a special case. Apparently the version of the Q70 that has good headlights doesn't have adequate forward collision prevention technology. And the one that has good forward collision tech doesn't have good enough headlights. We've provided the entire list of vehicles below in alphabetical order. Interestingly, it seems the Volkswagen Group is having the most difficulty providing good headlights with its otherwise safe cars. It had the most models on the list at 9 split between Audi and Volkswagen. GM is next in line with 7 models. It is worth noting again that though these vehicles have subpar headlights and don't quite earn Top Safety Pick awards, that doesn't mean they're unsafe. They all score well enough in crash testing and forward collision prevention that they would get the coveted award if the lights were better.

2022 Mercedes-Maybach S 580 First Drive | This thing rules

I can’t help but giggle to myself cruising around in the 2022 Mercedes-Maybach S 580. It is so absurdly good at its intended purpose. Just like a Porsche 911 is to performance, the latest Maybach is to all-out luxury. Much of the MaybachÂ’s goodness is thanks to the excellence of the new S-Class. Technological innovations like rear-wheel steering, E-Active Body Control and the latest MBUX software systems, all found in the new S-Class, establish a very lofty floor for the Maybach version of the car to build upon. And yes, when you pay the Maybach S 580Â’s exorbitant $185,950 base price, you get a whole lot more than just the standard S-Class experience. Appearances are half the battle with mega-luxury yachts like this car. The Rolls-Royces and Bentleys of the world are formidable on the road, and this Mercedes-Maybach puts up a good fight. It all starts with the 7-inch-longer wheelbase, most of which youÂ’ll see represented in the massive “comfort rear doors.” And we do mean “comfort” — they electronically swing open or shut via a switch on the ceiling or via a touch to the pop-out door handles. A massive radiator-style grille replaces the comparatively subdued grille in the standard S-Class. The C-pillar is noticeably more upright in the Maybach, and it features a light-up Maybach logo that reminds everybody about how rich you are, even at night.  And lastly, thereÂ’s the utterly breathtaking two-tone paint — pictured in Obsidian Black/Manufaktur Diamond White here — that costs $12,750 extra, but is genuinely worth the coin. Robots first spray the whole body in the lower halfÂ’s color, then the dividing line is hand-painted before both it and the lower part of the car is masked off for the top color to be hand-applied by MercedesÂ’ expert painters. There are lots of steps that were just left out, but know that the process can take up to a week in the custom paint shop before the body is returned to the regular production process. The end result of all these changes is a sedan that is both deeply different in character but also recognizable as the S-Class it is based on. ItÂ’s also just as imposing and rich-looking as a Bentley Flying Spur, so donÂ’t worry about being out-classed in the country club parking lot. Deciding which seat to occupy — the driverÂ’s seat, or the lounge-like rear seat — on the way to said country club might be the most difficult decision any Maybach S 580 owner will have to make on any given day.
