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.

Brazil contemplates safety exemption for VW Kombi as it goes out of production today [w/poll]

Brazil: the country of carnivals, indescribable beauty adjacent to abject poverty, Ayrton Senna and old Volkswagen models. Only they're not old - they're new, they're just based on old designs. The original Beetle continued production there long after it had been phased out elsewhere, but the original Kombi van has lasted much longer. That ends today, however, with the iconic VW Microbus ambling out of production on the last day of 2013.
VW kept making the van in Brazil with the original air-cooled 1.2-liter boxer four until 2005, after which the original design was updated with a 1.4-liter water-cooled engine. Today, however, it ultimately falls prey to safety regulations that mandate that all vehicles - no matter how old their design - need to have airbags and ABS, forcing Volkswagen do Brasil to cease production of the Microbus after a 56-year production run. But the latest word is that the Kombi (as it's presently known) could get a stay of execution - or at least a resurrection in short order.
According to reports, the Brazilian government is looking into granting the Type 2 Microbus an exemption from said safety regulations, reasoning that the van was designed long before the advent of airbags and ABS. If the measure goes through, the Kombi Last Edition (pictured above) could prove not to be the last at all. So what do you think, should the Microbus get an exemption from Brazilian safety regulations for nostalgia's sake? Vote in our poll below, then have your say in Comments.

Volkswagen Caddy gets the Alltrack treatment for Frankfurt

We've seen Alltrack versions of the VW Golf and Passat. The German automaker's commercial vehicles division has even done a concept version of the Multivan with a similar treatment. And now it's taking that same rugged off-road approach with the Caddy van. The new Caddy Alltrack starts off with the latest, fourth-generation city van revealed earlier this year in Geneva, and beefs it up to replace the previous Cross Caddy. That comes down principally to black trim on the wheel arches, side sills, bumpers, and underbody protection with metallic accents. It also packs unique 17-inch alloys, fog lights, chrome trim on the grille, silver roof rails, a new optional beige metallic paint (pictured), and Alltrack logos galore. The interior has similarly been worked over with unique trim. Though no mention has been made of any suspension upgrades, the Caddy Alltrack can be specified with 4Motion all-wheel drive. Prospective buyers (in markets where VW offers its commercial vehicles line) will also have to choose between passenger and panel van body-styles, and between four diesel and three gasoline engine options. They range in output from 74 to 123 horsepower and come mated to manual or dual-clutch transmissions with five, six, or seven gears. Look for the new Caddy Alltrack to highlight the Volkswagen Commercial Vehicles display at the Frankfurt Motor Show opening later this week.

The successor to the Cross Caddy is called the Caddy Alltrack. Like its predecessor, it is available both in passenger car and panel van formats. The latest version of the urban delivery van and family MPV is clearly distinct from the other Caddy models with its exclusive 17-inch alloy wheels 'Quito', new Mojave Beige metallic paintwork and optional 4MOTION all-wheel drive technology.
