Mercedes-Petronas AMG W04 launched to little fanfare, lots of pressure [w/video]

No indoor cocktail hour for the launch of the W04, the newest chassis built by the Mercedes AMG Petronas Formula One team. Instead, Nico Rosberg and Lewis Hamilton spent a morning in photo and video sessions at the track in Jerez, Spain then paused a moment to introduce the car. The team will want the W04 to demonstrate the World Championship credentials of the team personnel and one of the team drivers, instead of the mostly humble performances we've seen over the past three years.
The W04 has been fitted with a new five-element front wing, pushrod front and pull-rod rear suspension, a second-generation Coanda exhaust and an "aggressively packaged" rear end. A small vanity panel, à la Infiniti Red Bull's RB9, covers the stepped nose.
Team principal Ross Brawn has called it "a clear step forward in design and detail sophistication," but as much as we truly respect Brawn's abilities and achievements, we heard him say similar things about the updated W03 last year before almost every race weekend from about mid-season. We really hope he's right this time, and so does the team's newest driver, Lewis Hamilton. We'll do our best to ignore the parallels of the Mercedes F1 team having signed a sponsorship deal with Blackberry, another company trying to find its way back to the top and still struggling, and just point you to the video below of the W04 in action.

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.

Mercedes-Maybach SUV concept headed for Beijing reveal in April

Mercedes-Benz has toyed with the idea of a Maybach SUV for at least 11 years. According to Autocar, we'll finally see a concept with production intent at the Beijing Motor Show next month, the luxury SUV slated for market release next year. As has been the rumor for at least six years, the Maybach people carrier will be based on a stretched version of the GLS, which moves to the company's new Modular High Architecture with the 2019 model. Back in 2007 when Maybach was its own brand and selling roughly 300 units per year, Car magazine reported that brand chiefs were interested in convertible versions of the Maybach 57 and 62 sedans, and an SUV. Maybach built a one-off concept based on the GL — the former GLS-Class — in 2009, but never took the idea further. The rumor popped up again in 2014, then in 2015, reaching not-if-but-when status early last year. A decade on, it's finally time to play the hand. Even though the super-luxe SUV would sit on a stretched version of what is already a three-row SUV, it's reasonable to expect the Maybach SUV will only get two rows. That would give designers plenty of extra room for seating luxury and amenities even beyond the S-Class Maybach. On the other hand, if Mercedes sticks to the rough Maybach playbook so far, a triple-row Maybach would be the only such SUV in the mid- to upper-six-figures. The S-Class 560 4Matic starts at $102,990, the S 560 4Matic Maybach starts at $168,600. Applying that spread to the $94,500 GLS 550, you'd land around $160,000 before adding the markup for a new generation. That kind of starter pricing might make a great tweener proposition. Mercedes could focus on a range of buyers who want to go upscale from the $125,300 AMG GLS 63, without needing to worry — yet — about challenging Bentley and Rolls-Royce. Power is said to come from some version of the company's oft-applied 4.0-liter twin-turbo V8 that puts out 462 horsepower in the S 560, but the 3.0-liter inline-six hybrid in the S 560e is under consideration. We'll know next month, when the lightly veiled concept takes the stand in China. The full-on production version should get an introduction at this year's L.A. Auto Show. Related Video:
