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.

Next VW GTI to get 10-speed dual-clutch gearbox

Following on Volkswagen's official announcement that it was working on a ten-speed, dual-clutch transmission, Auto Express has it on "good authority" that the new transmission will end up in the next GTI, GTD and Golf R. The brand's current seven-speed will be retained for lesser eight-generation Golfs. While the new gearbox won't be limited to just the higher-end Golf range, the new hatchback, expected in 2017, will be the first to get it, Auto Express reports. The new DSG is the same size as the Volkswagen Group's seven-speed dual-clutch, and will easily fit into VAG's MQB platform, so we should expect it to filter into the rest of the Group's vehicles, much like the seven-speed 'box has. The ten-speed is likely to see applications beyond even the small cars of the MQB platform. The gearbox can handle 405 pound-feet of torque, according to AE, making its application in larger offerings such as the gas-powered MLB cars and crossovers a likelihood. Beyond the new gearbox, Volkswagen is also toying with mild-hybrid tech for the standard Golf and better batteries for the e-Golf. As we said, expect the new Golf to arrive in European markets in 2017, with the current Euro-market Golf getting updated next year. As for the US, we wouldn't be surprised if VW followed the trail blazed by the Mark 7, with a North American arrival for the eight-gem Golf slated for a year or so after sales in Europe begin.
