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.

Lots of new cars were unveiled in Munich this week. Here's what you might've missed

The 2021 Munich Auto Show is happening this week and due to ongoing corporate travel restrictions, we remained firmly planted on this continent. So, although we can't tell you exactly what it's like inside the futuristic new Mercedes EQE electric sedan or fully appreciate the funky Volkswagen ID.Life concept, there's no shortage of details and analysis to provide.  Obviously, as Germany's premier auto show in 2021, the cars unveiled were primarily from the German brands. We also focused mostly on the cars that might actually make their way to the United States, or at least inspire those that will.   2023 Mercedes-Benz EQE is an electric alternative to the E-Class While the EQS paved the way for Mercedes' electrified future, much like the S-Class before it, the EQE stands to be the car that will move in far greater numbers -- much like the E-Class before it.

Though perhaps a tad derivative of the Honda E, Volkswagen's blocky little crossover EV nevertheless represents a handsome new direction for VW design. We like this better than the rounded looks of the current ID.3 and ID.4.  2021 Volkswagen ID.Life concept View 20 Photos   BMW i Vision Circular is a 100% recycled and recyclable hatch Behold, the next BMW 3 Series! Just kidding. Besides this, BMW displayed cars in person for the first time that it had previously only unveiled on the interwebs, including the new 2 Series and revised iX3. It also unveiled some bikes. BMW i Vision Circular Concept View 63 Photos   Audi's GrandSphere concept was designed as a road-going private jet Does Audi know what a sphere is? Cause this isn't anything like one. Still, it's quite a handsome thing, and as one of three Sphere-branded concepts, previews the next direction of Audi design (which is pleasantly reminiscent of two-decade-old Mazda design). No complaints here. 2021 Audi GrandSphere concept View 26 Photos   Porsche Mission R is a 1,000-horsepower electric monster Just like the Mission E previewed the Taycan, this apparently previews another future car.

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.
