Editors' Choice: Top Five 2013 Geneva Motor Show Debuts

We've returned from a very busy week in Switzerland, and in going back over all of our 75 stories from the Geneva Motor Show, our editors have gathered up their personal favorite debuts from the European expo.
The wonderful thing about the Geneva show is just how wide of an array of vehicles are on display - everything from funny little one-off EVs to the most exotic of supercars to, well, truly ridiculous displays of coachbuilding. And because of that, this list of our editors' favorites might not be as predictable as you think.
But we don't want to give anything away just yet. Scroll down to have a look at our team's favorites from Geneva.

Volkswagen promises more aggressive design for sedans, crossovers

Every one of our Volkswagen Jetta and Passat reviews is guaranteed to include this word in the comments, aimed at its exterior design: "Boring." The brand says that's all about to change, telling a group of journalists during a tour of its design studio in Wolfsburg that designs will be more market specific; as Automotive News put it, that means "more aggressive" designs for the US that "will bare their teeth and flex their muscles," since the solid-yet-unoffensive look hasn't got VW past its two-percent market share here. Yes, we've heard this before from the Volkswagen Group - Audi has been promising to pump up the volume on its designs for years now, we're still waiting to hear that music. But VW brand head designer Klaus Bischoff says that the look of the coming midsize crossover that will come in around the size of the Audi Q7 "has to be bold. It has to be a statement," and the results of US focus groups have already dictated design changes to the original idea. AN said it takes cues from the Cross Coupe GTE, with a notched grille, sculpted hood, and deep character lines along the flanks. It sounds like baby steps for other models, though. The Passat gets a brand new design forward of the A-pillar, and new taillights. The new Tiguan has a shorter front overhang and a longer rear overhang, rounded wheel arches, and gets 2.2 inches longer. There'll be a long-wheelbase version of the Tiguan that grows by eight inches, which should give it livable room for four passengers in front and back. Beneath that will be a Golf-based crossover to compete in the compact segment with the Honda HR-V and Mazda CX-3.

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.
