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.

2017 Aston Marin Lagonda could live on Mercedes M-Class platform

A few weeks ago, we brought you news from the launch of the Aston Martin Vanquish Volante that the British brand, which is formally known as Aston Martin Lagonda, was still planning on going ahead with a Lagonda-badged crossover. Now comes word that that vehicle could very well be based on a Mercedes-Benz M-Class.
When the first Lagonda Concept debuted at the 2009 Geneva Motor Show, it sat on a Mercedes-Benz GL-Class platform, some four years before Aston Martin and Mercedes-AMG deal was inked. And with that partnership, which will see Aston Martin gain access to AMG electrics and "bespoke, V8 powertrains," the opportunities for platform sharing are many.
Dr. Ulrich Bez, the boss of Aston Martin, told the UK's AutoCar, "I look at what Porsche is doing with the 911 as its core business and then it is able to do models like the Cayenne based on the Volkswagen Touareg. It is good business." We've said many times that we'll tolerate exotic CUVs and SUVs if it means keeping the beloved core models alive, which has been the case with Porsche. We see no reason Aston Martin wouldn't be able to do the same.

2021 Mercedes-Maybach GLS 600 is business class without the jet lag

Mercedes-AMG demonstrated how sporty a mammoth SUV can be by unveiling the 2021 GLS 63 S at the 2019 Los Angeles Auto Show. Across the Pacific, at the Guangzhou auto show in China, Mercedes-Maybach revealed another GLS variant that puts an unabashed focus on comfort. The 2021 GLS 600 ends years of rumors by finally taking Maybach into the SUV segment. (If you don't count the limited-edition G 650 Landaulet). It's not a standalone model developed from the ground up, and it's in no way related to the electric Vision Mercedes-Maybach Ultimate Luxury concept introduced in 2018. It's a second-generation GLS dressed up in a Hugo Boss suit. Stylists spruced up the front end with Maybach's chromed waterfall grille and mesh inserts in the lower part of the bumper. An abundance of chrome trim (including big slabs of it in on the B-pillars) and Maybach emblems on the D-pillars further set the SUV apart from its non-Maybach-badged sibling. Buyers can order a two-tone paint job at an extra cost. 6.8-foot-long running boards automatically extend from under the body about a second after one of the passengers opens a door. Designers took advantage of the cavernous interior to replace the second- and third-row seats with a pair of business class-like chairs that offer heated, ventilated, massaging and reclining functions. Maybach developed the GLS with chauffeur-driven buyers in mind, so the passengers traveling in the back benefit from their own infotainment system with wireless headphones, folding tablets, wireless device chargers, plus heated and cooled cupholders. Alternatively, buyers can order the GLS as a five-seater with a three-person rear bench. The GLS 600 receives the twin-turbocharged, 4.0-liter V8 engine that's omnipresent in the Mercedes range. It delivers 550 horsepower from 6,000 to 6,500 rpm and 538 pound-feet of torque between 2,500 and 5,000 rpm in this application, and it spins the four wheels via a nine-speed automatic transmission and 4Matic all-wheel drive. Mercedes pegs its zero-to-60-mph time at 4.8 seconds. The standard 48-volt mild hybrid system briefly gives the GLS 600 an additional 21 horsepower and 184 pound-feet of torque. It also sends the kinetic energy it recuperates to the battery pack while braking or coasting, and powers a technology named E-Active Body Control which scans the road ahead and adjusts the suspension as needed if it detects a pothole, a bump or another obstacle.
