Aston Martin and Mercedes-AMG formalize technical partnership

The development of a partnership between Mercedes-Benz and Aston Martin has been a long time coming. The news dates back to 2008, and over the five years since was supposed to lead to a rejuvenation of both the Maybach and Lagonda brands. That program ultimately fell apart, but the tie-in was forged afresh in July when the two automakers signed a letter of intent over a renewed partnership. And now that partnership has been formalized.
In a deal just announced, Mercedes-AMG will build a new V8 engine for Aston Martin that will power a new generation of luxury GTs for the British marque, presumably to replace the 4.7-liter V8 in the Vantage. The relationship appears to be similar to the one already in place between AMG and Pagani, only in this case, will involve Daimler taking as much as a five-percent stake in Aston Martin and an observer seat on Aston's board.
The technical partnership is also set to lead to the supply of electric and electronic systems, and could incorporate "additional areas of cooperation in the future." Whether that will include a fresh attempt at reviving Lagonda remains to be seen, as does the future of Aston's long-serving, Ford-based 6.0-liter V12 engine. But for now you can read the full announcement below.

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 surprised Hamilton with this steering wheel message

Lewis Hamilton had much to celebrate at the end of the Abu Dhabi Grand Prix this past weekend. Not only did he win the race in commanding form (the 33rd in his career to make him the fifth most successful in Formula One history), but he also scored enough points (double on the season finale this year) to outpace his teammate and chief rival to win the world championship. Having already been crowned champion in 2008, that makes him one of only sixteen drivers to have won multiple world titles. It's a point his team at Mercedes didn't want him to miss, so on the cool-down lap at the end of the race, his pit crew radioed him the message "default 44" – an instruction that triggered this image to appear on the display in the middle of his steering wheel. Apparently Lewis, with plenty else on his mind (like getting his car back to the parc ferme in one piece and with enough fuel), didn't notice what was flashing in front of him. Superimposed, as you can see, over an image of Hamilton as a young lad still in karts is Lewis' name alongside those of the other two-time world champs: Jim Clark, Graham Hill, Emerson Fittipaldi, Alberto Ascari, Fernando Alonso and Mika Hakkinen. (Never mind those who've scored more than two titles.) Intriguingly, Hakkinen is the only other one among them to have won either of his titles under Mercedes power like Lewis did, though Fangio won two of his five titles motivated by Benz engines.
