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.

As VW electrifies, it questions the role of Lamborghini, Bugatti, Ducati

FRANKFURT — Volkswagen needs to change to stay relevant in the electric and digital vehicle era and will announce "important steps" to that end before the close of the year, Chief Executive Herbert Diess said on Wednesday. "Volkswagen needs to change: From a collection of valuable brands and fascinating combustion-engine products that thrill customers with superb engineering — to a digital company that reliably operates millions of mobility devices worldwide," Diess told shareholders at the company's virtual general meeting. Vehicles need to stay in contact with customers, offer new services and comfort functions on a weekly or even daily basis, he said. "We will take further important steps to set the course for this in the rest of 2020," Diess said. Senior executives told Reuters the company is reviewing what role its high-performance brands Lamborghini, Bugatti and Ducati will play as the company increasingly focuses on electric, digital and autonomous vehicles. Volkswagen, which also owns VW, Audi, Porsche, Seat and Skoda, is looking at whether it has the resources to accelerate development of electric platforms for smaller brands at a time it is investing billions to transform its more mainstream cars. Asked whether Ducati, which is known for making noisy combustion-engined motorbikes, has an electric future, Markus Duesmann, who oversees research and development for the group, said: "It will not take long until we see an electric Ducati." Whether Ducati, which is a medium-sized premium motorbike brand, would offer an electric variant, depends on whether a bike could offer range comparable to a combustion-engined variant, Duesmann said. Advances are being made in battery technology which could make this possible, he added. Separately Frank Witter, the company's chief financial officer, in response to a question about whether a sale of Lamborghini is planned, said Volkswagen does not comment on speculation about potential divestments. Lamborghini's Chief Executive Stefano Domenicali this week announced his departure from the sports car maker to take on a new job as president of Formula One. VW needs cash Volkswagen is reviewing the future of these three high-performance brands as part of broader quest for more economies of scale as it shifts to mass producing electric cars, senior executives told Reuters.

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.
