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.

The Vision Mercedes-Maybach 6 is pure electric excess

The Vision Mercedes-Maybach 6 is a two-door, two-passenger coupe that spans over 18 feet long. Everything about this car is more than you need. But isn't that the true definition of ultimate luxury? With so much sheet metal, it can be tricky to get everything to look right, but Mercedes seems to have done nicely with this concept. Overall, the car's long nose and short deck are reminiscent of the Mercedes-AMG GT, and the long, tapering tail and lights are similar to that of the Mercedes-AMG Vision Gran Turismo concept from a few years ago. Capping off the front of the Mercedes-Maybach 6 is a proud, prominent grille that the company claims was inspired by a pinstripe suit. At each corner are 24-inch wheels with transparent panels based on the transforming, aerodynamic wheels of the Concept IAA Mercedes previously showed. Powering this massive coupe are four electric motors that can produce a combined 738 horsepower. Mercedes says that will be enough to get the car to 62 mph from a standstill in under 4 seconds. The motors are backed by an 80 kWh battery that the company says can propel the car up to 200 miles. Perhaps more interesting than its range is the fact that the Mercedes-Maybach 6 can pick up a charge worth 62 miles in just 5 minutes, assuming you've got the right charger. This is technology that could really make a difference in the day-to-day practicality of electric cars, provided that it makes it to reality. The car can be charged either by being plugged in, or wirelessly with an inductive charging system. Inside, the Vision Mercedes-Maybach 6 has even more fantastical features. It does retain analog gauges as a link to the past, but augments them with wrap-around glass trim that doubles as a display and touch-sensitive interface. The windshield seems to be pulled from Mission Impossible with its ability to display information. Sensors in the seats are designed to read the condition of the passengers and even their outfits to custom tailor everything from lighting to massage features. It's hard to say what the production odds are for this mega Mercedes, but you probably shouldn't hold your breath. Even for the rarified segment of seven-figure cars, this would be pretty extravagant. It wouldn't be impossible, or without precedent. Back when Maybach was still its own brand, the company created a ridiculous luxury coupe called the Exelero, and they sold the fully-functional car.

Best compact SUVs of 2023 and 2024

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.
