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.

Tanner Foust checks out his new VW Beetle GRC rally car

Racing driver and Top Gear USA host Tanner Foust is a very busy guy. After all, he's competing in rounds of both Global Rallycross series and FIA World Rallycross Championship, not to mention his TV duties. However, we probably shouldn't feel too sorry for him, because his job puts him behind the wheel of some truly crazy machinery.
Case in point is his latest ride in Global Rallycross - the Volkswagen Beetle GRC. The German company claims that this all-wheel drive Bug makes around 540 horsepower from its 1.6-liter turbocharged four-cylinder and can shoot to 60 in under 2 seconds. Plus, if this video is any indication, this Volkswagen sounds like a machine gun when throwing revs at idle, and it can do some wonderfully easy four-wheel drifts.
Previously, Foust was driving a VW Polo for Andretti Autosport in GRC, but the team unveiled the look of the Beetle GRC at the Chicago Auto Show. Now, Foust is finally getting to show off his new office to the public, and like VW's tagline for the new car claims, it's way hotter than Herbie.

Chrysler and Fiat offering $1,000 rebates to VW owners as Marchionne gets tough

The throw-down between Fiat CEO Sergio Marchionne and Volkswagen has heated up in earnest. According to Bloomberg, Fiat and Chrysler are now offering current Volkswagen owners in the US $1,000 rebates to trade in their ride. It's the latest in a series of shots Marchionne has taken at his German rival. As you may recall, the Fiat executive entered into a spat with Volkwagen board chairman Ferdinand Piëch and CEO Martin Winterkorn in October after the duo called for Marchionne's resignation from presidency of the European Automotive Manufacturers Association (AECA). At the time, the Volkswagen executives were quoted as saying Fiat would not survive the European economic downturn.
In response, Marchionne called the German executives "reprehensible," and accused Volkswagen of using a pricing strategy that has created created a "bloodbath" in the EU. Volkswagen has taken to steep discounting to carve out ever-larger slices of market share in Europe, but the company has a much smaller foothold in the US. Marchionne may be trying to hit Volkswagen where the manufacturer is weakest with the new Fiat new incentive program.
Late last week, the Fiat executive was voted to a second term as ACEA president.
