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.

Race Recap: 2015 US Grand Prix was wet, wild, and historic

Hurricane Patricia made landfall in Mexico this weekend, and made her presence known throughout the South. For two of the three days of the grand prix weekend it rained non-stop in Austin, so badly on Saturday that qualifying had to be postponed until Sunday morning, and then it only stayed dry enough to conduct the first two sessions. At the end of a tricky, slippery Q2 Nico Rosberg had put his Mercedes-AMG Petronas on the front row, one tenth ahead of teammate Lewis Hamilton. The German had done the best he could to keep his hair-thin chances of a World Championship fight alive. Daniel Ricciardo lined his Infiniti Red Bull Racing chassis in third ahead of teammate Daniil Kvyat, both drivers having moved up a place because Ferrari driver Sebastian Vettel took a ten-spot grid penalty for using a fifth engine and dropped to 13th. Continuing the two-up theme, Sergio Perez and Nico Hulkenberg were fifth and sixth for Force India. After that came variety: Felipe Massa in seventh for Williams, Max Verstappen for Toro Rosso in eighth, Fernando Alonso looking good in the rain for McLaren in ninth, and Romain Grosjean for Lotus in tenth. When the lights went out, Turn 1 set the tone. Pole position is on the outside line at Circuit of the Americas, and Hamilton had got himself far enough under Rosberg by the time the two got up the hill that Rosberg had to stick to the outside through the corner. At the corner exit Hamilton used the entire track, pushing Rosberg wide, their cars touching. As Rosberg left the track and dropped back to fourth, Hamilton radioed to the team to say the contact was unintentional. The two Mercedes' and two Red Bulls animated the front. Rosberg passed Ricciardo at the end of a Virtual Safety Car period employed to let the marshals clean the debris at Turn 1. Kvyat started chasing down Hamilton until the Russian ran wide and let Rosberg and Ricciardo through, then Rosberg ran wide on the next lap to let Ricciardo through. On Lap 15, Ricciardo passed Hamilton through the esses to take the lead. After the first round of pit stops the Aussie still had the lead, followed by Rosberg, Kvyat, Hamilton, and Vettel. Then Rosberg got around to take the lead and Vettel closed in on Hamilton as the Brit duked it out with the Russian. Rosberg showed excellent speed, building up a nine-second gap on Ricciardo, but a Safety Car period erased that when Marcus Ericsson had to park his dead Sauber on the inside of the track after Turn 10.

8 automakers, 15 utilities collaborate on open smart-charging for EVs

We're going to lead with General Motors here. GM is one of eight automakers working with 15 utilities and the Electric Power Research Institute (EPRI) at developing a "smart" plug-in vehicle charging system. Why did we start with GM? Because it's the first automaker whose press release we read that mentioned the other seven automakers. Points for sharing. For the record, the collaboration also includes BMW, Toyota, Mercedes-Benz, Honda, Chrysler, Mitsubishi and Ford. The utilities include DTE Energy, Duke Energy, Southern California Edison and Pacific Gas & Electric. The idea is to develop a so-called "demand charging" system in which an integrated system lets the plug-ins and utilities communicate with each other so that vehicle charging is cut back at peak hours, when energy is most expensive, and ramped up when the rates drop. Such entities say there's a sense of urgency to develop such a system because the number of plug-in vehicles on US roads totals more than 225,000 today and is climbing steadily. There's a lot of technology involved, obviously, but the goal is to have an open platform that's compatible with virtually any automaker's plug-in vehicle. No timeframe was disclosed for when such a system could go live but you can find a press release from EPRI below. EPRI, Utilities, Auto Manufacturers to Create an Open Grid Integration Platform for Plug-in Electric Vehicles PALO ALTO, Calif. (July 29, 2014) – The Electric Power Research Institute, 8 automakers and 15 utilities are working to develop and demonstrate an open platform that would integrate plug-in electric vehicles (PEV) with smart grid technologies enabling utilities to support PEV charging regardless of location. The platform will allow manufacturers to offer a customer-friendly interface through which PEV drivers can more easily participate in utility PEV programs, such as rates for off-peak or nighttime charging. The portal for the system would be a utility's communications system and an electric vehicle's telematics system. As the electric grid evolves with smarter functionality, electric vehicles can serve as a distributed energy resource to support grid reliability, stability and efficiency. With more than 225,000 plug-in vehicles on U.S. roads -- and their numbers growing -- they are likely to play a significant role in electricity demand side management.
