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

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.

Watch this perfectly nice Mercedes get crushed by a front-end loader

In a world where the YouTube hoax continues to thrive, it's hard to know what to think of this little vid, but here are the facts as we know them: a coupe that looks like a first-generation Mercedes-Benz CLK gets crushed by a giant front-end loader. There you have it.
Our questions arise in the aftermath - we know industrial resource machinery is heavy, but the Benz gets squashed so flat we wonder if someone's trying to play a joke on us. We hear that the white coupe may have been the heavy-equipment operator's foreman's car, but who knows? The on-camera interview seems awfully conveniently placed, yes? See for yourself in the video below and then leave us your thoughts in Comments.
