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.

Recharge Wrap-up: 2015 Honda CR-Z now on sale, Daimler and Linde building hydrogen stations in Germany

The 2015 Honda CR-Z hybrid is now available at dealerships, for slightly more money. The CR-Z starts at an MSRP of $20,145 (plus $790 in destination charges), up from the $19,995 price of the 2014 model. For those who don't want to row their own gears with the six-speed manual transmission, the available CVT adds an extra $650 to the price, but also offers better fuel economy, especially in the city. The manual-equipped CR-Z gets 31 mpg city/38 highway/34 combined, while the CVT version is rated at 36/39/37 mpg. The 1.5-liter engine and electric motor provide a combined peak 130 horsepower. The manual CR-Z offers 140 pound-feet of torque, with the CVT version providing 127 pound-feet. Customers can also soup up their new CR-Z with upgrades (including a supercharger) from Honda Performance Development. Learn more in the press release below. Daimler and Linde are teaming up to build hydrogen fueling stations in Germany. The automaker and gases and engineering company, with the help of a few oil and gas companies, plan to install 13 new stations by the end of 2015. The installations precede a push by Daimler to get more fuel cell vehicles on the road. "From 2017, we are planning to bring competitively priced fuel-cell vehicles to market," says Daimler's Herbert Kohler. "So now is the time to build a nationwide fuelling infrastructure." Linde will supply the stations with fully renewable hydrogen. Read more in the press release below. In 1899, an EV set a world landspeed record, and Wired has revisited the story with a nice look back at the "La Jamais Contente" and its driver, Belgian engineer Camille Jenatzy. Jenatzy built an electric car to race in a hillclimb, which he won while clocking a top speed of 17 miles per hour (measured the old-timey way - without radar guns). Just a few weeks later, another man set a landspeed record of 32 miles per hour, beginning a back-and-forth series of setting new records. Then, on April 29, 1899, "The Red Devil," as Jenatzy became known as, surpassed 100 kph (62 mph) when his torpedo-shaped electric car set a record of 65.8 mph. It was powered by two 25-kilowatt electric motors. Read the whole story over at Wired.

Editors' Picks April 2021 | Honda Accord, Mercedes-Benz E-Class and more

The month of April saw us award Editors' Picks status to a couple mega-luxury vehicles and a couple long-time standbys that recently went through mid-cycle refreshes. We drove plenty of other cars that didn't quite reach the bar for Editors' Picks status — BMW 4 Series, Infiniti QX55 and the Mitsubishi Outlander among others — but the four you'll see below stood out as the best this month. In case you missed our previous couple Editors' Picks posts, hereÂ’s a quick refresher on whatÂ’s going on here. We rate all the new cars we drive with a 1-10 score. Cars that are exemplary in their respective segments get EditorsÂ’ Pick status. Those are the ones weÂ’d recommend to our friends, family and anybody whoÂ’s curious and asks the question. The list that youÂ’ll find below consists of every car we rated in April that earned the honor of being an EditorsÂ’ Pick. 2021 Aston Martin DBX 2021 Aston Martin DBX View 16 Photos Quick take: With attractive styling and a gorgeous yet functional interior, the V8-powered DBX is a legitimate crossover worthy of the Aston badge. Score: 8 What it competes with: Bentley Bentayga, Lamborghini Urus, Rolls-Royce Cullinan, Mercedes-Maybach GLS 600 Pros: Mega style, fantastic driving dynamics, a true and faithful Aston Martin Cons: Very expensive, only average infotainment From the editors: Editor-in-Chief Greg Migliore — “The DBX captures the spirit of Aston Martin in a modern crossover. That's not an easy thing to do. I expected the DBX might look the part, but lack functionality. Or it would be a decent crossover, but fall short of my idea of an Aston. The DBX did neither. It exceeded my expectations and is an entertaining vehicle to drive. The styling is interesting and evocative, and the AMG-sourced powertrain delivers proper performance. I also loaded it up with groceries and a carseat fits pretty well. Mission accomplished for Aston." In-depth analysis: 2021 Aston Martin DBX First Drive Review | A crossover that makes you forget itÂ’s a crossover   2021 Bentley Flying Spur 2021 Bentley Flying Spur V8 View 20 Photos Quick take: There are technically competitors to the Flying Spur, but nothing matches it stride-for-stride in every category. ItÂ’s the Bentley flagship product now, and it flies the brandÂ’s flag with both gusto and excellence. You can't go wrong whether you spec the W12 or V8 either.
