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 feuds with thriving stablemate Skoda

BERLIN, Oct 4 (Reuters) - Volkswagen managers and unions are seeking to curb competition from lower-cost stablemate Skoda, move some of its production to Germany and make the Czech brand pay more for shared technology, company sources told Reuters. As VW struggles to cut jobs and spending at German factories and turn the page on dieselgate, Skoda's superior car reviews and profitability have intensified the brands' rivalry within the Volkswagen empire. VW now wants to reduce what it sees as Skoda's unfair advantages - combining German technology with cheaper labor - and reaffirm the top-selling brand's primacy ahead of a wave of new electric car launches, the sources said. The tussle between VW and Skoda is reviving tensions at the heart of the Volkswagen group between profits and jobs, and between central control and autonomy for its 12 vehicle brands. "Instead of devoting our efforts to beating Tesla, we may just be setting up a futile internal conflict," said one manager. Once the butt of jokes, Skoda has blossomed under 26 years of VW group ownership into a successful mid-market carmaker, steadily winning business from rivals - including VW - and surpassing even Audi's operating profit margin last year. At the same time, VW is facing thousands of job cuts as management moves to trim excess capacity at German factories. Its powerful domestic unions see Skoda's success as both a threat and a potential lifeline. VW workers' representatives are now demanding the transfer of some Skoda production to their underused German plants, a source close to the supervisory board told Reuters. The proposal aims to offset declining output of the VW Passat and aging Golf that could otherwise threaten more jobs. They are also making the case that Skoda should pay higher royalties to use VW's main common vehicle platform. The so-called MQB architecture also underpins mid-sized models from the group's Audi and SEAT brands. Responding to the news, Czech Prime Minister Bohuslav Sobotka said he would meet Skoda management and unions to ask for clarification. The government will seek to ensure that VW investment plans are followed through and that "production is not moved outside the country," a statement released by Sobotka's office said. Skoda's main union warned that a production shift could cost as many as 2,000 jobs. VW's works council declined to comment.

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.
