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.

Lamborghini, Aston Martin, Mercedes-AMG, Porsche and Koenigsegg Lego sets coming this summer

Lego has announced a slew of new automotive-themed sets. As is typical fashion for brand of building toys, the subject matter leans toward ultra-exotic, ultra-expensive vehicles, ranging from a $139,000 Mercedes SL63 on the low end to a $3 million Koenigsegg Jesko Absolut on the high end. If you can't afford those cars in real life, soon you'll be able to build your own plastic models of them. Some of the real-world counterparts aren't obtainable no matter what the cost. Take the Lamborghini Lambo V12 Vision Gran Turismo, for example. The one-off concept was designed by Lamborghini exclusively for Gran Turismo, the PlayStation racing simulator. However, Lamborghini did build a 1:1 version for the physical world, with the 808-horsepoewer hybrid V12 from the Sian FKP 37 beneath its bodywork. The Lego version is part of the company's Speed Champions line, which measure about 6 inches long. It does an excellent job of capturing the original's insectoid look and Y-shaped taillights. The set is made up of 230 pieces and will retail for $26.99. This is Lego's first Vision Gran Turismo car but we hope to see more.  Also joining the Speed Champions line are two 2-car sets. An Aston Martin-themed set pairs a Vantage safety car with an AMR23 Formula 1 racer. Both are finished in AMR's bright green with actual sponsor logos. The set contains 564 pieces and will cost $44.99. Also arriving as a 2-car set are a pair of Mercedes-AMGs. A black G 63 and yellow SL 63 Roadster, along with a pair of sunglasses-clad bros, make up the 808-piece set. It also retails for $44.99. All three Speed Champions sets arrive on June 1, 2024. If you're looking for something a bit more advanced and detailed, Lego also offers the Technic line. First up is a Porsche GT4 e-Performance, a 1,000-horsepower race car based on the 718 Cayman. This set can also function as a remote controlled car that moves forward, backward, and steers via a downloadable smartphone app. The 834-piece set costs $169.99. Last but not least, there's the Koenigsegg Jesko Absolut, a model of the Swedish supercar that is said to have a top speed of over 300 mph. The model does an admirable job of capturing the car's 0.278 Cd drag coefficient, considering it's comprised of 801 individual plastic bricks. This set will retail for $49.99 and, along with the Porsche, comes out August 1, 2024. Related Video LEGO Speed Champion Build: 1968 Ford Mustang Fastback

2015 Spanish F1 Grand Prix makes its Deutsche mark

The first race of the European Formula One season inaugurates the second phase of the Championship. Teams overhaul their cars with the big updates they've been working on since Australia, and at the end of The Battle of Spain we find out how the positions on the field have changed. Mercedes-AMG Petronas driver Nico Rosberg brought a big update to his psychology, straight-up beating teammate Lewis Hamilton to take his first pole position of the season. Mercedes owns the front row and Ferrari maintains its status as primary challenger, Sebastian Vettel lining up in third. Williams proved it's been hitting the books to do better in class, though, Valtteri Bottas slotting into fourth. And Toro Rosso's visit to a track that rewards strong aero rewarded them with the best team grid position since the Italian Grand Prix in 2008: Carlos Sainz secured fifth, ahead of Max Verstappen in sixth. Kimi Raikkonen's bout of Saturday woes – it seems the Finn is always handicapped by lots of tiny issues – continued in Barcelona with one of his sets of prime tires getting cooked by malfunctioning tire warmers. He recovered well enough to take seventh on the grid, but he's got some strong competition ahead of him. He led three other drivers in the Continuous Issues department, Daniil Kvyat unable to wrestle his Infiniti Red Bull Racing higher than eighth, Williams driver Felipe Massa getting it wrong in Turn 3 to fall five places behind his teammate Bottas, and Daniel Ricciardo in the second Red Bull enduring another engine change and sloppy car behavior to get tenth. And while it turned out to be a steady race a little rough around the edges, the positions on the battlefield just might have changed. A little. Of the 66 laps in the race we might have seen Rosberg for three of them – maybe. The German got a smashing start, had a clear lead into Turn 1, and after that we checked in occasionally during his two pit stops and again at the checkered flag. He owned the entire weekend the way we're used to seeing his teammate do, and the cameras left him alone to run his race. No one got within seven seconds of him during the first third, and as the pit stop strategies played out that cushion grew. He finished seventeen seconds ahead of Hamilton, and 45 seconds ahead of third-placed Vettel. Hamilton, on the back foot all three days, stumbled out of the gate.
