Volkswagen Group previews its wares on eve of Geneva show

The Volkswagen Group is comprised of 11 brands producing 240 vehicles across 49 factories throughout the world. So the best way to show off the range of the VW family is to cram a few thousand journalists and VIPs into a massive makeshift stand to outline the Group's goals, what's in the pipeline and what you'll be able to buy later this year.
To that end, VW pulled out all the stops on the eve of the 2012 Geneva Motor Show, bringing along 10 vehicles from across the range. We'll be delving into the details of each over the next two days of show coverage, but before that happens, you can read all about what we saw tonight from the cheap seats after the break.

Updated J.D. Power APEAL study shines on VW Group, Chevy

J.D. Power has just revealed the results of its 2013 APEAL Study, which looks at which brands have the most appealing cars based on sales figures, dealer inventory, brand loyalty, transaction and trade-in prices. The study was revamped for 2013, and places a larger focus on the new tech and infotainment options available to customers. All told, study participants gauged their vehicles on 77 different attributes, delivering a score out of a 1,000 points.
The Volkswagen Group had the greatest success of any corporation, topping the APEAL rankings with the Audi Allroad, Porsche Boxster, Porsche Cayenne, VW GTI and Passat. Chevrolet had the highest number of awards for a single brand, though, with the Avalanche, Sonic and Volt all taking home a prize.
The best brand overall was Porsche, which scored 884 out of a possible 1,000 points. The top Japanese brand was Lexus with a score of 847, while the top American brand was Cadillac, at 841. The best mainstream brand was Ram, which received a very respectable 817. The industry average for this year's study was 795, with 16 brands, all of which were mainstream, falling below the average.

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.
