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.

Volkswagen breaks 40-year-old sales record in 2012

The last time Volkswagen moved this many vehicles in America in one year, Richard Nixon was still a President in good standing, Let It Be was a radio hit and each car wearing the VW badge boasted an air-cooled engine. That's right, with a grand total of 580,286 vehicles sold in the US last year, the VW Group has broken its own four-decades-old sales record by 2,899 vehicles.
Of that 580k total sold, 438k were Volkswagens and 139k were Audi products - increases of 35.1 percent and 18.5 percent, respectively, in year-over-year sales. The ultra-premium members of the VW group also fared well; Bentley delivered 2,315 vehicles for a 23.3-precent increase, and Lamborghini delivered 520 units for a 52.9-percent jump. Bugatti, we're told is "right on track."
Jetta (pictured) sales paced the marque with 170k models sold, and Passat also finished very strong with sales of 117k total. Tiguan also racked up its best year on file, with 31,731 models shifted.
