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 throws a Polo-palooza with four new or upgraded models

Volkswagen unveiled a parade of new and upgraded Polo models at the 2014 Geneva Motor Show, including the Polo TSI BlueMotion, Polo TDI BlueMotion, Polo BlueGT and CrossPolo (pictured above). While they will likely never make an appearance this side of the pond, it is fun to see what European subcompact drivers will be driving later this year.
The new BlueMotion models represent the most efficient petrol and diesel options in their class, according to VW. The BlueMotion TDI offers just 73 horsepower from its diesel engine but gives the equivalent of 76 miles per gallon (US) in the EU test. The BlueMotion TSI brings a little more power with its 88-hp petrol engine and has a combined rating of 57 mpg (US) in the EU cycle.
The Polo BlueGT provides a balance of performance and economy, and for the 2014 model, it gains a 9-horsepower boost to its 1.4-liter turbocharged to give drivers 147 hp at the press of the accelerator. This year's car also has an optional Sport Select suspension with electronically controlled dampers to improve handling a bit. It's still fitted with active cylinder management to use as little gas as possible when cruising.

VW, Suzuki mulling rekindling relationship in face of legal battle

Volkswagen and Suzuki have been undergoing marriage counseling in a bid to avoid finalizing their nasty divorce. The blissful union has been troubled for some time, with Volkswagen claiming that it could affect operational decisions at Suzuki, and the Japanese brand's sniping and constant flirting with a certain Italian temptress causing rifts.
The matter first went to court in 2012, when Suzuki demanded VW get out, and leave its 19.9-percent stake in the Japanese brand in a box to the left. Now, Automotive News is reporting that the company will give the relationship one last shot, according to closed-door dealings between the two in London.
Still, it's understood that VW and Suzuki recognize the benefit of their alliance, and that it'd be in the best interests of the kids both parties to make things work. Spokespeople declined to comment to AN, but the newsmagazine spoke with Frank Biller, an analyst for LBBW in Stuttgart, who said, "Both companies stand to benefit if they can overcome the disagreements over leadership claims."
