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.

Drive like a prince: Join us for a walk through Monaco's car collection

Small, crowded, and a royal pain in the trunk lid to drive into during rush hour, Monaco sounds like an improbable location for a huge car museum. And yet, this tiny city-state has been closely linked to car culture for over a century. It hosts two major racing events every year, many of its residents would qualify for a frequent shopper card if Rolls-Royce issued one, and Prince Rainier III began assembling a collection of cars in the late 1950s. He opened his collection to the public in 1993 and the museum quickly turned into a popular tourist attraction. The collection continued to grow after his death in April 2005; it moved to a new facility located right on Hercules Port in July 2022. Monaco being Monaco, you'd expect to walk into a room full of the latest, shiniest, and most powerful supercars ever to shred a tire. That's not the case: while there is no shortage of high-horsepower machines, the first cars you see after paying ˆ10 (approximately $11) to get in are pre-war models. In that era, the template for the car as we know it in 2023 hadn't been created, so an eclectic assortment of expensive and dauntingly experimental machines roamed whatever roads were available to them. One is the Leyat Helica, which was built in France in 1921 with a 1.2-liter air-cooled flat-twin sourced from the world of aviation. Fittingly, the two-cylinder spun a massive, plane-like propeller. Government vehicles get a special spot in the museum. They range from a Cadillac Series 6700 with an amusing blend of period-correct French-market yellow headlights and massive fins to a 2011 Lexus LS 600h with a custom-made transparent roof panel that was built by Belgian coachbuilder Carat Duchatelet for Prince Albert II's wedding. Here's where it all gets a little weird: you've got a 1952 Austin FX3, a Ghia-bodied 1959 Fiat 500 Jolly, a 1960 BMW Isetta, and a 1971 Lotus Seven. That has to be someone's idea of a perfect four-car garage.  One of the most significant cars in the collection lurks in the far corner of the main hall, which is located a level below the entrance. At first glance, it's a kitted-out Renault 4CV with auxiliary lights, a racing number on the front end, and a period-correct registration number issued in the Bouches-du-Rhone department of France. It doesn't look all that different than the later, unmodified 4CV parked right next to it. Here's what's special about it: this is one of the small handful of Type 1063 models built by Renault for competition.

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.
