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.

Autoblog's adventures at the Nurburgring 24-Hour race [spoilers]

The brand-new Audi R8 LMS, said to share 50 percent of its components with the street-legal R8 shown off at Geneva, has won its very first race at the 2015 Nurburgring 24-Hours. The No. 28 car driven by Christopher Mies, Edward Sandstrom, Nico Muller, and Laurens Vanthoor for the Audi Sport WRT team out of Belgium finished only 40.279 seconds ahead of the No. 25 BMW Sport Team Marc VDS Z4 GT3 in second place, for the smallest winning gap since the race began in 1970. Those two cars traded the lead throughout Sunday morning and were less than a minute away from one another for the last two hours. They were part of a total 35 lead changes during the entire race – a record for the event – and both did 156 laps. Third place went to the No. 44 Falken Tire Porsche 997 GT3, one lap down. The Audis did what they always do: lurked close to the front, stayed out of trouble, then pounced when everyone else faltered. For the opening stretches the BMW Z4 teams owned it, running 1-2-3 for a while, but all of them hit trouble. When morning came and the race got over its yellow-flag fever, the No. 28 Audi was in front and stayed there. It was the third Nurburgring 24-Hour win for Audi in four years, the brand's first win only coming in 2012. Last year's winner, the Phoenix Audi team that set a race record by doing 159 laps, had both of its cars retire. One hit an oil patch about 12 hours in, spun and was hit by another car behind, taking on too much damage to continue. The other retired with engine issues. Other Notes Three cars crashed out of the race while leading, after the rains that weren't supposed to happen, happened about 90 minutes in. The No. 20 Schubert BMW Z4 led the first 50 minutes of the race, hopped a crest at Pflanzgarten, landed in a pool of water, and hit the wall on the 30th lap. Then the No. 30 Frikadelli Porsche, with a driver team that included ex-'Ring Taxi driver Sabine Schmitz, hit the No. 31 Mercedes SLS AMG GT3 on the approach to Carrousel and crashed out. Then the No. 1 Phoenix Audi, last year's winning car, took the lead but hit the wall after that oil patch near Pflanzgarten and was out of the race. Aston Martin celebrated a class win in the SP8 category with the No. 49 Vantage GT4 N430. This being the tenth anniversary of the Vantage running the Nurburgring-24, this year's car was painted in the same colors as the racecar from ten years ago.

VW looking to MAN up, ditch Mercedes van deal

Unlike the US, the commercial truck market throughout the rest of the world is chocked full of competitors from many different automakers. Since 2006, Volkswagen has had a fullsize van called the Crafter that was a result of a partnership with Daimler AG and based on the Mercedes-Benz Sprinter. This partnership is supposed to last through 2016, but Reuters is reporting that VW might be looking to end its relationship with Daimler and create its own van in cooperation with German truck and bus maker MAN.
The article says that VW AG has more than a 75-percent stake in MAN, which would essentially be keeping the new commercial vehicle in-house. Even if VW bolts, Daimler still has a deal worked out in the commercial truck industry between its subsidiary Mitsubishi Fuso and Renault-Nissan to supply the other with different trucks.
