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.

What is the most expensive car in the world?

Highlighting one single vehicle as the most expensive car in the world isn't as straightforward as you might think. To get a solid answer, we're going to have to break the question into a couple of parts. First, we'll discuss the most expensive new car in the world, and second, the most expensive collector car in the world. And by the end of the article, you'll be armed with the information you're looking for: What is the most expensive car in the world? Before we get into the stratospheric numbers, let's take a step back and put things in perspective. For the last year or so, the average transaction price for a new car has hovered right around $48,000. That's almost 10 grand more than new cars cost in 2019, before the pandemic. What will that buy you today? Well, you can get a midrange Ford F-150, a Kia Telluride, or a Ford Mustang GT with a few options. Not bad when you consider that these choices are among the best in their respective classes. At the very bottom of the spectrum is the Nissan Versa, which is available brand new for well under $20,000. Sure, there are a few anomalies such as the Changli Nemica (it's kinda a car, though not exactly street legal here in America) that can be ordered from Alibaba for about $1,000 to start, but there are a bunch of hidden costs, including shipping. Most expensive car in 2024: Rolls-Royce Droptail Price: $30 million Outside of the classic car market, the most expensive new vehicle in the world is the Rolls-Royce Droptail. So far, three Droptail models have been built, one called the Arcadia Droptail, one in ruby tones called La Rose Noire Droptail and one called the Amethyst Droptail. The latest example, the Arcadia, is painted in a white shade that is infused with aluminum and glass particles for a pearl-like effect that adds depth. Past that, the overall design of all three Droptails remains largely unchanged with an upright grille, thin rear lights, and a rounded back end. Like other extremely luxurious and expensive nautical-themed cars from Rolls-Royce — see the 2017 Sweptail and the 2021 Boat Tail — the Droptail is a very rare machine. There's a solid chance the lone remaining version will cost even more than the $30 million-plus cost of the La Rose Noire. For those keeping track, the Rolls-Royce Boat Tail, which was previously the most expensive car in the world at $28 million, was the first model to emerge from the company's Coachbuild department that caters to the profanely wealthy.

2016 Formula 1 Chinese Grand Prix recap: another wild show on and off track

Normally we use this space to provide a lengthy recap of the weekend's Formula 1 race, but we're going to try something different since most folks reading this know what happened at the Shanghai International Circuit on Sunday. Instead, we'll alight on what we saw as the big issues in and around the race. Let us know what you think in Comments. Proper qualifying is back. Thank goodness. It only took a month of embarrassment to fix it. And so is passing! For the third race in a row, big performance improvements at the ten teams behind Mercedes-AMG Petronas and a wider tire selection at this race graced us with opening stints filled with dicing cars. Seeing the McLarens on screen doesn't make us cringe. Manor doesn't only make the global feed when it's being lapped. We've been complaining about parade races for so long that we forgot excitement was possible without rain or wholesale regulation changes. Yes, Mercedes is still the king of the jungle, but there are some other proper midfield beasts on the hunt, too. Malfunctions up and down the grid did help the show in Shanghai, like Lewis Hamilton suffering perpetual troubles, Nico Hulkenberg's runaway front wheel which red-flagged Q2, and Sebastian Vettel's and Kimi Raikkonen's flubbed hot laps in Q3 that let Daniel Ricciardo slip by into second on the grid. Come race day things went all Grand Theft Auto at Turn 1 on the opening lap, sending some of the best cars to the pits. Then came Ricciardo's puncture while leading, then came the Safety Car – all by Lap 5. Nico Rosberg got 38 seconds of airtime on the way to victory – at the start and the finish, and that happened to be his margin of victory, too – otherwise he was a ghost. Everyone else was struggling and juggling. Rosberg's win at the Bahrain Grand Prix put the German at five consecutive victories going back to last year's Mexican Grand Prix. The history books show that any driver who's won five straight contests has gone on to win the championship. With his triumph in China, the German has won the season's first three races, the history books again show that the other nine drivers who've pulled that off have gone on to win the championship. Rosberg, 36 points ahead of his teammate in the standings, is having none of it. He said of the other victors, "But they didn't have Lewis Hamilton as their team-mate." Perhaps Mercedes was right not to make an engine deal with Red Bull last season.
