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.

Best Large SUVs of 2024

When it comes down to large SUVs, there's more to consider than price and just how large it is. First, it comes down to what's underneath the skin. Some are built on a truck-like body-on-frame chassis — this would be the traditional, literal definition of an "SUV." Others use car-like, unibody construction, which would make them a crossover. What really matters, though, is how you use them. For most American families, a large three-row crossover is going to be your best bet. They have loads of passenger and cargo space, and deliver superior fuel economy, handling and ride quality than those big traditional SUVs. They're cheaper, too. On the other hand, those traditional large SUVs like the Chevy Tahoe and Ford Expedition are better-suited for more heavy-duty tasks like towing. Most now have bigger third rows than big crossovers, while extended-length versions like the Chevy Suburban have way more cargo capacity behind their third rows than everything but an airport shuttle. As for luxury large SUVs, they fall into those same two categories as well, with American choices mostly being truck-based. The pros and cons of choosing one over another are similar. Below, you will find our list of the best large SUVs broken down into three categories: large family crossover, large traditional SUV and large luxury SUVs, which comprise both construction types.  Best Large Family Crossovers  |  Best Large Traditional SUVs  |  Best Large Luxury SUVs Best Large Family Crossovers 2024 Honda Pilot Why it stands out: Exceptional storage and cargo space; unique second-row functionality; refined ride; versatile and capable TrailSport; advanced AWDCould be better: Subpar acceleration with lackadaisical transmission and engine response; so-so driver assistance tech Read our full 2024 Honda Pilot Review The Honda Pilot was completely redesigned for 2023. It maintains its predecessor's family-friendly packaging and overall focus, but it has injected a welcome sense of style (especially in the TrailSport pictured above) that makes it stand out much better from the big crossover crowd. The Pilot's restrained adornment and classic proportions are refreshing compared to the increasingly busy Kia Telluride, Hyundai Palisade and Subaru Ascent. Let's talk about practicality, though, which is ultimately the Pilot's best attribute.
