VW reveals Outback-rivaling Golf Alltrack ahead of Paris

The Volkswagen Passat Alltrack is getting a baby brother at this year's 2014 Paris Motor Show in the form of a new Golf Alltrack. Like its larger sibling, the little wagon is supposed to offer light-duty off-road driving ability combined with a more rugged look to show it off.
To give the Golf Alltrack that soft-road ability, VW is outfitting the wagon with its latest 4Motion all-wheel drive system from Haldex. The setup can decouple power from the rear-axle when not needed to save fuel. To further improve traction, the Alltrack gets VW's electronic differential lock, and the car can individually brake its inside wheel during hard cornering for better handling.
Volkswagen also wants the Alltrack to be able to visually show that it can handle getting away from the pavement, even though it starts life as a standard Golf wagon. That means jacking up the suspension an extra 0.75 inches and adding black moldings all the way around the car. There are also redesigned bumpers for the front and rear and silver underbody protection, plus new accents like anodized roof rails and silver mirror caps. The interior is essentially unchanged from the wagon, except for altered trim and Alltrack badges.

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.
