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.

Volkswagen planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.

Volkswagen Group names Paefgen head of classics program

You may remember the name Franz-Josef Paefgen. Until recently, the German engineer and executive was head of both Bentley and Bugatti. Before that he was chief executive of Audi, after working for several years at Ford. He technically "retired" earlier this year, but like the cars he helped create, an executive like Paefgen could never really retire. So it should come as little surprise that the Volkswagen Group has named Dr. Paefgen head of its Classic program.
In his new capacity, Paefgen will oversee the historic automobile activities of the entire VW Group, including those of Volkswagen, Seat, Skoda, Audi, Lamborghini, and of course Bentley and Bugatti. It strikes us as a suitable semi-retirement for the man responsible in no small part for the Bugatti Veyron and Bentley Mulsanne, to name just two, and who was decorated in 2006 by the ACO as the "Spirit of Le Mans" for his contribution to endurance racing.
