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 compact SUVs of 2022

Compact SUVs are now the go-to choice for family transportation. Actually, considering how popular they are, they have clearly moved beyond only family duty. With such popularity, though, comes an awful lot of competitors, and it can be difficult to figure out which one might be the best compact SUV for you.  It's important to note that by "compact SUV" we're talking about a specific segment. As we describe in our more comprehensive "Best small SUVs" list, there are also subcompact SUVs that vary widely in size amongst themselves, but are clearly smaller than the SUVs below. Frankly, today's segment of compact SUVs isn't exactly compact — some have more cargo space than vehicles that are considered midsize based on their exterior dimensions. They've all grown considerably over the years. While many lists out there just rattle off every vehicle available in a segment, we thought we'd be a bit more helpful and curate your shopping a bit with the top-recommended choices reviewed by Autoblog. We've included both mainstream and compact luxury SUV choices. Best compact SUVs of 2023 and 2024 2024 Honda CR-V Why it stands out: Best-in-class space; excellent hybrid powertrain; sharp interior style; Honda dependabilityCould be better: No lower-price base trim levels; no sporty or off-road niche models; no plug-in hybrid Read our full 2024 Honda CR-V Review Consider the CR-V the baseline for any compact SUV search, and look extra closely at the superb CR-V Hybrid option. Objectively speaking, it's tough to beat due to its massive cargo capacity, voluminous back seat, strong-yet-efficient engines, well-balanced driving dynamics, competitive pricing and features,  and well-regarded reliability. It's easy to see why it continues to be such a best-seller: for the vast majority of compact SUV buyers, and especially families, it checks every box. That's been the case for many years now, however. The all-new 2023 Honda CR-V changes things up by adding a bit more style and character, particularly in terms of its interior design and how surprisingly enjoyable the Sport and Sport Touring hybrid trim levels are to drive.
