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.

Last VW bus ever made arrives at final destination

A Brazilian politician tried to save it, unsuccessfully, so the final Last Edition Volkswagen Type 2 Kombi was produced on December 20, 2013 and now resides in a vintage museum at Volkswagen's Commercial Vehicles HQ in Hanover, Germany.
The Volkswagen Microbus was built for 56 years, starting in September 1957. Brazil was the last country still assembling it, but new safety regulations in the country requiring airbags and ABS on all cars spelled the end. When that politician introduced a bill that would pardon only the 'Bus from a death sentence, it couldn't garner the required number of votes for passage. The South American country takes the Kombi production title, though, with 1.5 million of the 3.5 million total made in the home of Copacabana beach and the girl from Ipanema.
The VW Bus is dead. Now perhaps we can turn our attentions to the still-not-totally-settled matter of the Bulli...

How the VW diesels perform in cheat mode

Are you tired of the Volkswagen diesel emissions scandal? Yeah? We are, too. But here's a story that, at the very least, gives us something resembling answers about one of the most important questions surrounding the firestorm – how will the affected cars perform when they're in their emissions-cheating test mode? Consumer Reports was able to find out, tapping into what it believes is the cheat mode. By turning the car to accessory mode, flipping on the hazards, and tapping the gas pedal five times, CR was able to defeat the auto-engaged traction and stability controls, which it believes activates cheat mode. The safeties will reengage if it detects the rear wheels spinning, so the next step was what CR called "a hack." The team unplugged the rear wheel sensors, so the car's computers couldn't tell whether the wheels were spinning. By the way, don't try this at home. With that done, CR hit the road, testing both a 2011 Jetta Sportwagen TDI and a 2015 Jetta TDI sedan in their normal and cheat modes. Why both cars? Well, the 2011 uses the EA188 diesel, which represents the bulk of the affected cars, while the newer Jetta uses the latest EA288, which just arrived for model year 2015. The results are, in a word, interesting. The EA188 engine lost 0.6 seconds on the way to 60 miles per hour while in emissions-compliant cheat mode, and fuel economy fell from 50 miles per gallon to 46. For the newer EA288, the 0-60 difference was negligible – just a tenth of a second – while the fuel economy dipped from 53 to 50 mpg. There are a few takeaways here. First of all, and as suspected, running in cheat mode did hurt both performance and fuel economy. But perhaps more importantly, even in emissions-compliant mode, both vehicles easily beat their EPA fuel economy estimates. According to FuelEconomy.gov, the highest rated 2011 TDI Sportwagen, the manual-trans model, was rated at 30 mpg city and 42 mpg highway, with a combined rating of 34 (the auto drops the city and combined ratings by one mpg, while the highway falls by three). The best a 2015 Jetta TDI sedan can do according to Uncle Sam, meanwhile, is 31 city, 46 highway, and 36 combined with the manual (again, the auto is worse, but only by a single highway mpg).
