To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.

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.

Volkswagen names new chief designer for Bentley

The Volkswagen Group has named one of its own to head up the design department at its Bentley division. The role now falls to Stefan Sielaff, who has been with the group (off and on) since 1990. Sielaff is principally an interior designer, but has been tasked with setting up numerous overall design offices for Volkswagen and Audi over the years. In his new capacity he'll be reporting to the group's chief engineer Rolf Frech (and oddly not to Bentley chief Wolfgang Durheimer), but at the same time, Sielaff will retain his role as head of interior design for the entire VW group, reporting to its chief designer Walter de Silva. Sielaff replaces Luc Donckerwolke, who has headed up Bentley design since 2012 and is leaving the company. We'll be on the lookout to see where Donckerwolke lands next. Crewe/Wolfsburg, 04 June 2015 Stefan Sielaff to head design at the Bentley brand • Sielaff also responsible for Group Interior Design Strategy Stefan Sielaff (53), currently Head of the Volkswagen Design Center in Potsdam, will assume responsibility for design at the Bentley brand effective July 1, 2015 in addition to his present post as Head of Group Interior Design Strategy. As Director of Design at Bentley, Sielaff succeeds Luc Donckerwolke (49), who held this function since 2012. Stefan Sielaff joined the Volkswagen Group in 1990, beginning his career in the interior design department at Audi. From 1995 the design graduate was entrusted with setting up the Group's Design Center Europe in Spain. In 1997 he was placed in charge of the Design Studio in Munich and was appointed Head of Audi Interior Design in the same year. In 2003 Sielaff moved to DaimlerChrysler as Design Director of the Interior Competence Center, returning to the Volkswagen Group in 2006 to become Head of Audi Design before being appointed Head of the Volkswagen Design Center in Potsdam und Head of Group Interior Design Strategy in 2012. In his new function as Director of Design at Bentley, Sielaff reports to Rolf Frech, Board Member for Engineering. In his function as Head of Group Interior Design Strategy he continues to report to Walter de Silva, Head of Group Design. Luc Donckerwolke has decided to leave the company. De Silva said: "Luc Donckerwolke has played a key role in the design of various Group brands. We would like to thank him for his work."
