Daimler exec hypothetically discusses 3-cylinder engines for small hybrids

Is three the magic number of cylinders for Mercedes-Benz parent Daimler and its efforts to build smaller powertrains for its compact hybrids? Potentially, yes, the German automaker could see the need for three-cylinder mills, Automotive News reports. The company doesn't have any plans for them as of yet, though. Daimler executive Bernhard Heil talked with Automotive News about the challenges of using four-cylinder engines in a front-wheel-drive setup and said that three-cylinder engines could work in transverse-mounted powertrains for hybrid cars. For now, though, the company doesn't actually have any plans to go in that direction, Mercedes-Benz spokesman Christoph Horn said in an e-mail to AutoblogGreen. Horn wrote that Heil "actually said that if ever MB would use a three-cylinder engine than [it would be] in a configuration where space is restricted, such as when using a hybrid power train in a compact car." Of course, the only compact "hybrid" that Mercedes-Benz has is the 2015 C-Class, but that refers to the "hybrid" body is made of 48-percent aluminum, up from the current nine percent, as well as steel. It has nothing to do with the powertrain. Beyond that, there's always the Mercedes-Benz S500 Plug-in Hybrid that the company unveiled at the Frankfurt Motor Show last fall, but that model, which will debut in Europe later this year and arrive stateside next year, has a 3.0-liter turbocharged V6 and an 80-kilowatt electric motor that propels the plug-in from 0 to 62 miles per hour in 5.5 seconds. Not exactly three-cylinder territory, that.

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.
