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.

VW boss confirms Subaru-aping Golf Alltrack for US

Subaru needs to watch out, because the Japanese brand with a utilitarian image has a big bull's eye on its back. Not only is Acura considering going 100-percent all-wheel drive in a bid to mimic the successful automaker, Volkswagen has just confirmed that the Golf Alltrack is coming to the US as another competitor for Subaru's popular Outback crossover. Volkswagen Group of America CEO Michael Horn has confirmed the addition of the higher-riding, all-wheel drive version of the Golf SportWagen to Automotive News, indicating that the model will arrive in the US in 2016. "That's what our dealers, our customers, are asking us for," he said to the industry publication. The Golf Alltrack, which debuted at the Paris Motor Show in early October, has an extra 0.75 inches of ride height and protective black cladding all the way around. Its biggest mechanical differentiator from other Golfs is its Haldex all-wheel drive system, a setup that can completely unhook from the rear axle when not needed to save fuel. In Europe, the Alltrack is available with a turbocharged 1.8-liter with 178 horsepower and two diesels offering between 109hp and 182 hp. However, Horn made no mention of likely powertrains for the US. Horn tells Automotive News that all-wheel drive tooling is currently being installed at the Puebla, Mexico, factory where the standard Golf Sportwagen is built. VW might have tipped its hand about this possibility several months ago when press shots of the wagon were released for the US with TDI and 4Motion badges. Horn says he expects even the front-wheel drive version to be a sales hit here, suggesting it may eventually account for 50 percent of the Golf range's volume.

Volkswagen's 261-mpg hand-built XL1 headed for Geneva

After years of rumors, development and testing, the Volkswagen XL1 is finally about to become a reality. The project that began life as a daring 1-Liter concept car in 2002, will finally get its production-ready curtain call at the Geneva Motor Show in just a few weeks.
As soon as it hits the streets, the two-seat XL1 will instantly become the most fuel-efficient and most aerodynamic production car in the world. The car uses a plug-in hybrid system to achieve mind-blowing consumption of just 0.9 liters of diesel fuel consumed every 100 kilometers (and average of roughly 261 miles per gallon). Plus, the XL1 can go up to 50 kilometers on its battery power alone. Coefficient of drag is a miniscule 0.189, thanks to a tiny frontal area and an obviously slippery shape.
XL1 power comes from a two-cylinder diesel motor connected to a seven-speed dual-clutch gearbox, while the 20 kW electric motor is fed by a lithium-ion battery. Both combine to give the XL1 performance figures that are, while not stirring, not shabby considering its extreme frugality: 0-62 miles per hour comes up in 12.7 seconds and top speed is nearly 146 mph.
