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.

Recharge Wrap-up: Volvo's efficient truck concept, Tesla's updated mobile charger is cheaper

Mercedes-Benz plans to equip its gasoline-powered cars with particulate emissions filters, just like its diesel vehicles. Claiming to be the first automaker to apply the technology to gasoline motors, successful testing in the S500 led to the decision to expand the use of these filters. This announcement coincides with a $3.35 billion investment in clean diesel technology, including a new four-cylinder engine that adheres to strict emissions guidelines. It's not clear when Mercedes will begin including the filters on its gasoline vehicles, or if it intends to use them outside of Europe. Read more at Green Car Reports. Tesla has updated its mobile charger and given it a lower price. The 40-amp "Mobile Connector Bundle" – which used to sell for $650 – is now priced at $550 with two adapters and a storage bag, with an available $520 version offered without the adapters. Tesla's product description reads, "The Corded Mobile Connector has an integrated 240 volt 50 amp rated plug for high power output. A seamless design provides a low profile connection, allowing for use with covered outdoor outlets." Read more at Electrek. Volvo has developed a new truck concept that reduces fuel consumption by more than 30 percent. The modified Volvo FH 420 long-haul truck, simply called the Volvo Concept Truck, features 40 percent better aerodynamic efficiency, a weight reduction of about 4,400 pounds, and tires with lower rolling resistance. The truck's rear view mirrors have been replaced by cameras, which, in addition to reducing drag, also improve safety through better visibility. While the research vehicle won't reach market as-is, some of its aerodynamic features have already been included in real-world applications, with more to come as Volvo aims to improve the efficiency of its trucks by 50 percent. Read more at Green Car Congress, and in the press release below. Volvo Trucks' new concept truck cuts fuel consumption by more than 30% Almost one-third lower fuel consumption. Volvo Trucks' new concept vehicle shows how it is possible to drastically boost productivity in long-haul operations. Among the secrets behind these remarkable fuel savings are aerodynamic design and lower kerb weight. With support from the Swedish Energy Agency, Volvo Trucks has developed a new concept vehicle, the Volvo Concept Truck. It is the result of a five year long research project aimed at creating more energy-efficient vehicles.

Daimler wants to cut EV research spending as it preps EQ

Daimler AG is hoping that the legwork it's done preparing its EQ electric-vehicle sub-brand will allow it to slightly reduce annual spending on plug-in vehicle technology. The Mercedes-Benz parent is looking to cut electric-vehicle research-and-development spending to $13.2 billion in 2017 from about $15.4 billion this year, Bloomberg News says, citing comments Daimler CEO Dieter Zetsche made to journalists in Hamburg, Germany, this week. Daimler's annual R&D spending is up from about $11.5 billion in both 2013 and 2014. Like its competitors – for example Audi and BMW and its i sub-brand – Daimler is aiming to have as much as 25 percent of its annual vehicle sales be battery-electric within the next 10 years as part of an effort to meet stricter greenhouse-gas emissions mandates in both Europe and North America. In fact, Mercedes-Benz and Daimler's Smart division collectively have at least 10 electric-vehicle models on their slates during the next few years, though Zetsche said the German automaker will continue to find ways to make its gas- and diesel-powered vehicles more fuel-efficient as well. Daimler introduced a concept version of the Generation EQ electric SUV at the Paris Motor Show late last month. It comes powered by two electric motors and is made up of a combination of steel, aluminum, and carbon fiber, and boasts a 311-mile single-charge range (on the relatively lenient European testing standards). The SUV also has 402 horsepower, and the ability to go from 0 to 60 miles per hour in less than five seconds. Zetsche said at the time that Daimler was prepping powertrains and platforms for electric sedans, wagons, coupes, and roadsters, in addition to SUVs. Additionally, Daimler's Deutsche Accumotive unit is producing the lithium-ion battery packs for the EQs.
