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.

McLaren, Red Bull and Ferrari call for unfreezing F1 engines

Formula One is a hugely expensive sport. Not only do you have enormous salaries and logistical expenses, as you would in any other sport, but each team also spends huge sums developing their own chassis from the ground up – and so too do the participating automakers in developing the engines. One of the ways the series organizers mitigate those costs is by freezing development. So once the new crop of V6 turbo hybrid powertrains were developed, that was it. But now three of the of the sport's leading teams are calling on the FIA to unfreeze engine development. Their reason? Unfair advantage. There's little question that Mercedes did the best job of developing its "power unit" to meet the new regulations that took effect at the beginning of this past season. That's how the Mercedes team won all but three of the grands prix this season and finished with at least one car on the podium at every single race. It's also a big part of how the teams that bought their engines from Mercedes this season managed to consistently outperform the other non-works-supported teams. That clear advantage is why Red Bull, Ferrari and now McLaren are calling for engine development to be unfrozen. Their argument is that, under the current locked-down status quo, their engine suppliers (Renault, Ferrari and Honda, respectively) cannot possibly catch up. So unless the FIA and Formula One Management want the next few seasons to be the kind of absolute blow-outs that this past season was, these leading teams argue, the powers that be are going to have to make some changes. For its part, Mercedes naturally counters that unfreezing engine development would send costs spiraling out of control. But then of course it stands to lose the most by re-opening engine development. If those three teams, however, closely intertwined as they are with the three other engine suppliers participating in next year's championship, manage to solicit enough support from the other customer teams and bring the matter to a vote, Mercedes may very well find itself out-numbered.

Daimler eMERGE2 test proves ignorance breeds dislike of EVs

Out with the old EVs, in with the new. Daimler announced today that it has finished up the eMERGE electric vehicle project that used Smart Fortwo Electric Drive cars and will now start up eMERGE2, which will use Mercedes-Benz B-Class Electric Drive and PHEV vehicles. As before, the tests will take place in Germany. The first, just-finished eMERGE program ran from May 2013 to June 2015 and put over a million kilometers (621,000 miles) onto 146 Smart Fortwo EDs. Daimler said that over the two years, the vehicle with the most efficient annual energy consumption used just 10.4 kWh for all of its 100 kilometers. The best full-charge range over the year was 161 kilometers (100 miles). Perhaps most interesting, though, was one of the projects findings: "the less an interviewee knew about electric mobility, the more negative their opinion" about the technology. In other words, here's some more proof that getting "butts in seats," as it were, is one reasonable way to promote electric driving. eMERGE: key contribution to developing the mobility of the future Stuttgart/Berlin, Jul 30, 2015 Broad-based real-world trial of eMERGE project completed Especially for daily distances of 50 km or over the E-car is financially attractive eMERGE2 fleet project now launching with 200 Mercedes-Benz B-Class Electric Drive and plug-in hybrid models Stuttgart/Berlin – After more than one million kilometres in two years – from May 2013 to June 2015 – the real-world trial of electric cars known as eMERGE has been completed. Those taking part in the project were private and business customers with 146 smart fortwo electric drive cars from Berlin, Potsdam and North Rhine-Westphalia. Some of them set records: the lowest average energy consumption over one year was 10.4 kWh/100 km, while the longest range was 161 kilometres. The smart fortwo electric drive is certified with a consumption of 16.3 kWh/100 km and a range of 145 kilometres. The broad-based field trial within the framework of the eMERGE project has not only provided information on user behaviour and e-car technology; it also studied intelligent charging systems for improving the utilisation of the power supply as well as various pricing systems with regard to customer acceptance. Based on transport models, the project partners examined the need for a publicly available charging infrastructure. Within the project Daimler was responsible for collecting the driving and charging data required for evaluation of the field trial.
