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.

2015 Audi Q7 spotted with a blurry first look

Here's the good news: we finally have visual evidence of the upcoming and all-new 2015 Audi Q7 luxury SUV. A set of photographs show that Audi has been putting the SUV through its paces, with an eye towards an on-sale date sometime late next year.
The bad news is that it was not one of our usual clear-lensed spy photographers that captured these first images, but rather a sycophantic follower of our friends at CarPix. The resulting images are a lot lower resolution than we've come to expect, and there are far fewer angles from which to judge the car.
Still, we can make out the nose of the new Q7 is a bit flatter and wider than the rounded affair of the current car, and wears similar swoopy LED headlights as are found in the rest of the Audi range. We expect the overall dimensions of the 2015 Q7 to stay about the same as the existing model, but rumor has it that the SUV could be 800 to 900 pounds lighter in the next generation.

Winterkorn remains CEO of Volkswagen's majority shareholder

Martin Winterkorn may have stepped down as the chief executive of Volkswagen in the wake of the diesel emissions scandal, but he's not out from under the company's large umbrella just yet. In fact, according to a report from Reuters, he still holds four top-level positions not only within the industrial giant's bureaucracy, but at the top of it. And one of those is as CEO of the company's largest shareholder. That holding company is Porsche SE, the investment arm of the Piech and Porsche families (Ferdinand Porsche's descendants) which holds over 50 percent of VW's shares. In 2008, Porsche SE acquired majority interest in the Volkswagen Group which in turn acquired Porsche the automaker – and placed VW's Winterkorn at the head of the executive board of the holding company. Though Winterkorn has resigned from his position as chairman of VW's management board, he has apparently yet to step down from running Porsche SE. That's not the only job that Winterkorn still retains in VW's senior management. He also continues to serve as chairman of Audi, as well as truck manufacturer Scania, and the new Truck & Bus GmbH into which Scania has been grouped together with Man. It remains unclear if or when Winterkorn might resign from those positions as well, or how his tenure in those posts might affect the company's effort to start over in the aftermath of the scandal in which it is currently embroiled. Also unclear, Reuters reports, is how much, exactly, Winterkorn will receive in compensation after having stepped down from his chair at the head of the VW executive board. His pension is reported at over $30 million, but he could be awarded a large severance package as well amounting to as much as two years' worth of his annual compensation, which amounted to around $18 million last year. Whether he receives the severance pay or not is expected to depend on whether his resignation is considered by the supervisory board to have been the result of his own missteps or independent of the situation that resulted in his resignation. One way or another, he's not likely to go poor anytime soon.
