Volkswagen kills planned 10-speed DSG

If there are two things in this wild and crazy industry that keep growing, they are the size of cars and the number of gears in their transmissions. It wasn't ten years ago that cars with six forward gears – either manually or automatically shifted – were a relative rarity. Now, there are a multitude of sub-$30,000 cars with at least a six-speed automatic. But while eight- and nine-speed automatics are becoming increasingly common, no automaker has delivered a production ten-speed automatic (which may be a good thing, considering the reception to most nine-speed gearboxes). Ford and General Motors were collaborating on one as recently as April 2013, and Hyundai has was allegedly working on one way back in 2011. Most recently, though, Volkswagen announced a ten-speed, dual-clutch automatic in November 2014. And now, less than two years later, the project has apparently been shelved. That's according to our Vegemite-loving friends at Motoring.com.au, which report that both the cost and complexity of project has proved unfeasible for VW. "In the end, we had to balance what our priorities were with our transmissions and other things are more important and more urgent," an unnamed source at the Frankfurt Motor Show told the Aussie website. The ten-speed DSG was slated for a number of three- and four-cylinder models from VAG's entire range of affordable vehicles. It was also, allegedly, to feature in the ultra-high-performance Golf R400, Motoring reports. It's unclear how its cancellation will impact the company's future projects, if VW will look elsewhere for its small-car gearboxes, of if there's another – perhaps conventional – new transmission in the pipeline. Currently, VW's highest gear-count dual-clutch is the seven-speed DSG, shown above with company CEO Martin Winterkorn.

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.

Aurora's Chris Urmson on autonomy — that's one way to avoid speeding tickets

Although this year's CES was full of companies announcing and exhibiting their real and conceivable self-driving car technologies, while actual self-driving cars from Aptiv-Lyft were giving conventioneers 400 rides around town, the biggest news came when Volkswagen Group — and recognize this is the entire group, not just the brand — and Hyundai announced that they'd both partnered with Aurora Innovation. While the VW announcement was vague — "The collaboration brings the two companies together to realize self-driving electric vehicles in cities as Mobility-as-a-Service (MaaS) fleets" — Hyundai provided a concrete goal: "a strategic partnership to bring self-driving Hyundai vehicles to market by 2021." You may not have heard of Aurora, which has been described in some news accounts as "mysterious." But Aurora Innovation has been in business since December 2016, and it is to autonomous technology what the 1927 Yankees are to baseball. The three leaders of the company are Chris Urmson, co-founder and CEO, who had previously been chief technology officer for Alphabet Self-Driving Cars; Sterling Anderson, co-founder and chief product officer, who had directed the development of Tesla Autopilot; and Drew Bagnell, co-founder and chief technical officer, who had been autonomy architect and perception lead at the Uber Advanced Technology Center. We had the chance to sit down with Chris Urmson after he appeared onstage at a Hyundai press conference. He shared his insights on Aurora's approach to automated driving. Initial deployment of self-driving cars? "We think the first place this technology comes to market in in the transportation services or ride-hailing applications, but that's for our partners to decide." (Ride-sharing is a strategy a lot of players in the field are shooting for, as round-the-clock use is one way for paying for what will initially be a technology too costly for private ownership.) Transporting goods or people? "I personally — and as a company — am more excited initially about moving people around. Urban mobility. That's where you see the largest social impact. And it provides better access to mobility for people." Can you create a car that doesn't crash? "It is a fundamentally hard problem because other operators on the road can behave erratically at any moment. For example, if you are in a two-lane, opposing-traffic road, if you want to be safe, you don't drive there, ever.
