Which will Dieselgate hurt more, Volkswagen or US diesels?

The most damning response to the news Volkswagen skirted emissions regulations for its diesel models may have actually come from the Los Angeles Times. On Saturday, the Times published an editorial titled "Did Volkswagen cheat?" The answer was undoubtedly yes. When you can't drive down Santa Monica Boulevard without seeing an average of one VW TDI per block, the following words are pretty striking: "... Americans should be outraged at the company's cynical and deliberate efforts to violate one of this country's most important environmental laws." VW has successfully cultivated a strong, environmentally conscious reputation for its TDI Clean Diesel technology, especially in states where emissions are strictly controlled. A statement like that is like blood all over the opinion section of the Sunday paper. The effect on VW's business, even Germany's financial health, was already felt Monday when the company's shares plummeted 23 percent in morning trading. The statement on Sunday from VW CEO Dr. Martin Winterkorn says "trust" three times. That probably wasn't enough in nine sentences. Writers over the weekend have compared VW's crisis to one at General Motors 30 years ago, when it was the largest seller of diesel-powered passenger cars until warranty claims over an inadequate design and ill-informed technicians effectively pulled the plug on the technology at GM. In a sense, VW is in the same boat as GM because it has fired a huge blow into its own reputation and that of diesels in passenger cars. And just as automakers like Jaguar Land Rover, BMW and, ironically, GM, were getting comfortable with it again in the US. VW of America was already knee-deep in its other problems this year. Its core Jetta and Passat models are aging and it needs to wait more than a year for competitive SUVs that American buyers want. The TDIs were the only continuous bright spot in the line and on the sales charts. Even as fuel prices fell and buyers shunned hybrids, VW managed to succeed with diesels and show that Americans actually care about and accept the technology again. Fervent TDI supporters might actually lobby for that maximum $18 billion fine to VW. I've personally convinced a number of people to look at a TDI instead of a hybrid. Perhaps not so much for stop-and-go traffic, but I know buyers who liked the idea that a TDI drove like a normal car and wasn't packed with batteries.

Audi design getting big overhaul?

Car and Driver has an update on the design shuffle in Ingolstadt that will ultimately bring more differentiation to Audi products. Last November, Audi design chief Wolfgang Egger spoke of the need to do "something new without breaking from tradition" in Audi design, but talk at the time centered on how the Crosslane Coupe Concept would influence the new looks of the brand's Q cars. The most recent moves appear focused on passenger cars, with designers from Volkswagen Group kin like Bentley and Seat moving to Audi, and outsiders from Alfa Romeo moving in.
While Egger decreed the end of "scalable design" to CD, last November's report said there would be more technology and "greater visual cohesion" between interior and exterior design. We still have no idea what all this means nor when we'll see visible changes in production, but at least we know there's something being done behind the scenes.

Audi says new 48 volt micro-hybrid system improves fuel economy, paves way for electrification

Most cars use a 12-volt system to power their electrical components. But, with more and more electric bits and bobs being added to new vehicles, a dozen volts is looking a bit weak these days. In fact, Audi says that standard 12-volt systems are being stretched "to their very limits." Enter 48 volts. If used in a car that gets 40 mpg, that would translate to around 43.5 mpg. Audi is testing a supplemental 48-volt electric system in two prototype vehicles – modified mild-hybrid versions of the A6 TDI and the RS 5 TDI – in order to add in more electric technology (an electric compressor, for example, to improve acceleration) and "convenience systems for dynamic chassis control." Audi says it has more applications in the pipeline, but the overall gist is that the German automaker sees 48 volts as an "important building block in electrification strategy." As you can see in the picture above (click to enlarge), the RS 5 TDI concept uses a li-ion battery installed in the back of the car and an alternator to provide 48 volts when the engine is off. Audi says that the 48-volt system can save up to 0.4 liters of fuel per 100 kilometers. To put that into US numbers, if used in a car that gets 40 miles per gallon today, that would translate into a bump up to around 43.5 mpg. The Advanced Lead Acid Battery Consortium (ALABC) is also working on a 48-volt system to improve fuel economy and we've got a deep dive of Audi's electric turbocharger here. Even more powerful and efficient – the new 48-volt technology from Audi Important building block in electrification strategy More voltage and more power for new technologies Scalable platform concept suitable for wide-ranging uses Ingolstadt, August 25, 2014 – Audi is to upgrade part of its vehicle electrical system from twelve to 48 volts. The move represents another technical building block for facilitating the integration of new automotive technologies while increasing the power and efficiency of its cars. "We are using the full bandwidth of electrification in our drive principles strategy. Running part of the vehicle electrical system at 48 volts plays a central role in this," commented Prof. Dr. Ulrich Hackenberg, Member of the Board of Management for Technical Development at Audi. "It enables us to make more energy available.
