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.

Audi drives Laurel Canyon in reverse

With all its many twists and turns and narrow lanes, driving down Laurel Canyon Boulevard in Los Angeles demands your attention under the best of conditions. The driver caught on this video, however, is clearly not giving it his best. The driver behind the wheel of this new Audi – an S5 or maybe even an RS5 coupe, if our eyes and the low resolution don't deceive us – opted to drive down the canyon road entirely in reverse, with a woman in the passenger seat. The incident was caught on video by one Kevin Zanazanian, another motorist following behind. (Or would that now be considered in front? We're all turned around here). Fortunately the driver appears to have taken things at a rather leisurely pace. Which is a good thing, or at least a mitigating factor. While cars are designed to be able to back up, unless you're a stunt driver on a closed set, they're not meant to do so at speed. But then they're not meant to be driven backwards for extended lengths of time or distance, either. That's why local authorities are reportedly trying to track down the driver, who could have been held accountable for any number of infractions had he been caught in the act - including driving right through a red light, backwards, from the turning lane, across Hollywood Boulevard. With the video footage now in hand, the LAPD's West Traffic Bureau is reportedly working to determine who it belongs to, and who can be held liable for this stunt. With no injuries or damage reported, KTLA reports that the charges (however many of them) would not amount to more than misdemeanors.
