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.

Hamilton wins at Monza, takes Formula One lead from Vettel

MONZA, Italy (Reuters) - Lewis Hamilton won the Italian Grand Prix for Mercedes on Sunday with an utterly dominant drive that sent the Briton clear at the top of the Formula One world championship for the first time in a year. The triple champion, who started the last race of the European season from a record 69th career pole position, led Finnish team mate Valtteri Bottas to a runaway one-two finish at Ferrari's home track. "I love it here in Italy and I love the passion of the fans," Hamilton declared on the podium jutting out over a sea of red-shirted Ferrari fans, with plenty of boos coming his way amid the cheers. "We did a great job, the team did an exceptional job this weekend," he added. "Mercedes power is definitely better than Ferrari power." Ferrari's Sebastian Vettel, who had led the standings since he won the Australian season-opener in March, finished third in the final race of the European season and 36.3 seconds behind the winner. Bottas was 4.4 adrift of Hamilton. "It was a difficult day, a difficult start," said Vettel. "My race was fairly isolated, we tried to keep as close as possible but we simply didn't have the pace... You could say it's a bad day but I know the team is on the right way... so I am in a very positive mood despite the numbers." Hamilton is now three points clear of the German, with seven races remaining. Mercedes are 62 points clear of Ferrari in the constructors' standings. The first driver to win two races in a row this season, with Monza following on from Belgium a week ago, Hamilton now leads Vettel 6-4 on victories in 2017. He has 238 points to Vettel's 235. The last time Hamilton led the standings on his own was at Monza a year ago, with now-retired team mate Nico Rosberg emerging as the eventual champion. FEW THRILLS Hamilton and four-times champion Vettel were level on points this year after China in April, with one win and one second place each. If Sunday's race was a dull affair, there was at least plenty of sunshine in marked contrast to the steady rain that drenched fans and delayed qualifying for hours on Saturday. Hamilton pulled away cleanly from his historic pole, and fourth in a row at Monza, and was never challenged as he drove to the chequered flag with the minimum of fuss. It was his third Italian Grand Prix win in four years and 59th career victory – only Michael Schumacher, whose pole record he beat, can boast more – and few have been more straightforward.

2014 Mercedes-Benz E63 AMG rumbles on stage 4Matic style

Bruce Hornsby and his soothing piano skills helped introduce us to the 2014 Mercedes-Benz E-Class, but the monstrous E63 AMG sedan needed no entrance music as it rumbled on stage. The 550-horsepower (and up) sedan sat proudly alongside the rest of the redesigned E-Class on stage at the Detroit Auto Show, but stood miles apart in intention and execution.
In addition to a choice of sedan and wagon body styles, the E63 AMG will also offer buyers the choice of the standard 550 hp or an upgraded 577-hp S-Model; regardless of output, all 2014 E63 AMG models will come standard with the 4Matic all-wheel-drive system.
We already saw the E63 AMG's aggressive styling last week, but now we have a full assortment of live images for you to enjoy as well as the Mercedes-Benz press release, which is also posted below.
