Andretti Autosport partners with Volkswagen for Global Rallycross season

Michael Andretti and Volkswagen have both been involved in Global Rallycross for a couple of years, but not together. Andretti Motorsports Marketing organized the final round of the 2012 GRC series in Las Vegas, and there were rumors then that Andretti was going to get in. Around the same time there were news reports that Volkswagen was preparing a 600-hp Polo Mk5 to race in the SuperCar class; the photo above is racer Anton Marklund in his privateer Marklund Motorsports Polo at the 2013 X-Games round in Los Angeles.
Now it's official: Andretti Autosport will campaign the 2014 GRC season with VWs. That's all that's been said for now, Andretti being busy at the moment launching four entries for IndyCar, two for Indy Lights and two for Pro Mazda. We have a feeling we'll be seeing the MkVII Golf involved, but the cars and the driver lineup will be presented at the Chicago Auto Show on February 6.

VW confirms new TDI for second half of 2014 in Golf, Jetta, Passat and Beetle

Diesel lovers rejoice. Volkswagen is bringing the latest iteration of its 2.0-liter four-cylinder diesel engine - dubbed the EA288 - to the 2015 model year Golf, Jetta, Passat, Beetle (2013 model pictured above) and Beetle Convertible, and the cars will be on sale in the second half of 2014.
While it shares its moniker with the old diesel, the new engine produces 150 horsepower, a 10-hp boost, and 236 pound-feet of torque. VW promises improved fuel economy as well, but it hasn't announced specifically what amount yet. The company claims that despite the same displacement, only the bore spacing is shared with the previous version. The mill includes new features like exhaust gas recirculation, an intercooler integrated into the intake manifold and low-friction camshaft bearings.
VW Group of America has had great success with diesels in the US recently. Vee-Dub and Audi sold 105,899 diesel-equipped models in 2013. It was the first time the group ever sold over 100,000 diesels in a year, and they accounted for 24 percent of sales. Scroll down to read the full press release about the announcement.

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.
