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 Caddy hauls its cute self into Geneva

Here in the States, we have a small but growing segment of little people-and-stuff-carriers, including new things like the Ford Transit Connect, Nissan NV200, Ram ProMaster City, and so on. But in the Old Country, these little guys are everywhere, and hardly a new concept. One of Europe's best in this segment – the Volkswagen Caddy – has been given a thorough refresh, combining all of the great-to-drive characteristics of a Golf with the functionality of a Touran van. Buyers can choose between four different versions of the 2.0-liter diesel inline-four, or three gasoline engines in 1.0-, 1.2-, and 1.4-liter displacements. There's even a natural gas version. And with its Golf roots, your author is, shall we say, really, really interested in a GTI version of this little cutie. The Caddy you're seeing here is, obviously, a passenger van configuration with windows abound. Buyers can also opt for a panel van variant, for more secretive load-hauling. Have a look at the updated Caddy in the images above, and read all about it in the release below. The new Caddy – always the best choice – world premiere for the fourth generation of the best-seller - Entry-level price reduced due to new versions - Emissions and fuel consumption reduced by new EU6 engines - Safety increased by new driver assistance systems - Design refined with clear edge Hannover/ Poznan, 04 February 2015: Volkswagen Commercial Vehicles is showing the fourth generation of the hugely popular Caddy for the first time. Around 1.5 million of the award-winning previous generation were sold worldwide during its eleven years in production. A success that the new Caddy is intended to continue because the urban delivery van and its privately used brother have been enhanced and refined in every area. In Germany, prices for the new Caddy start at ˆ 14,785.00 (net, panel van) and ˆ 15,330.00 net (ˆ 18,242.70 gross, as Conceptline, replacing the previously familiar Startline), each with the 62 kW TSI entry-level engine and thus, when adjusted for feature content, are even below the level of the predecessor model. The drive systems use state-of-the-art technology, with the Caddy's new engines providing maximum efficiency and compliance with the EU6 emissions standard. The basis for the four TDI diesel versions is always a two-litre four cylinder engine. Their performance ranges from 55 kW / 75 h.p. to the top engine with 110 kW / 150 h.p..

A car writer's year in new vehicles [w/video]

Christmas is only a week away. The New Year is just around the corner. As 2014 draws to a close, I'm not the only one taking stock of the year that's we're almost shut of. Depending on who you are or what you do, the end of the year can bring to mind tax bills, school semesters or scheduling dental appointments. For me, for the last eight or nine years, at least a small part of this transitory time is occupied with recalling the cars I've driven over the preceding 12 months. Since I started writing about and reviewing cars in 2006, I've done an uneven job of tracking every vehicle I've been in, each year. Last year I made a resolution to be better about it, and the result is a spreadsheet with model names, dates, notes and some basic facts and figures. Armed with this basic data and a yen for year-end stories, I figured it would be interesting to parse the figures and quantify my year in cars in a way I'd never done before. The results are, well, they're a little bizarre, honestly. And I think they'll affect how I approach this gig in 2015. {C} My tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015 it'll be as high as 73. Let me give you a tiny bit of background about how automotive journalists typically get cars to test. There are basically two pools of vehicles I drive on a regular basis: media fleet vehicles and those available on "first drive" programs. The latter group is pretty self-explanatory. Journalists are gathered in one location (sometimes local, sometimes far-flung) with a new model(s), there's usually a day of driving, then we report back to you with our impressions. Media fleet vehicles are different. These are distributed to publications and individual journalists far and wide, and the test period goes from a few days to a week or more. Whereas first drives almost always result in a piece of review content, fleet loans only sometimes do. Other times they serve to give context about brands, segments, technology and the like, to editors and writers. So, adding up the loans I've had out of the press fleet and things I've driven at events, my tally for the year is 68 cars, as of this writing. Before the calendar flips to 2015, it'll be as high as 73. At one of the buff books like Car and Driver or Motor Trend, reviewers might rotate through five cars a week, or more. I know that number sounds high, but as best I can tell, it's pretty average for the full-time professionals in this business.
