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 imagines a world where mechanics are zombies

Warewolves, vampires, lab-created monsters... they've all come and gone from the silver screen, but the latest trend in apocalyptic popular media centers around zombies. And that's the theme Audi has tapped for its latest ad. The television commercial is called "Mechanics," and as you may have guessed by now, they're the zombies the German automaker is depicting. The spot was created to encourage Audi owners (like the one in this A5) to have their vehicles serviced at authorized dealers rather than taking them to independent garages that may not be after your brains, but might like a crack at your pocket book, at least (as if dealerships aren't). The commercial was created for Audi by Thjnk Berlin GmbH and directed by Sebastian Strasser for RadicalMedia, and is worth a watch for the laugh alone. Related Video:

Autoblog Minute: Nokia to sell Here mapping for $3.1B

In a three company partnership the German automakers BMW, Audi and Daimler are set to take ownership of Nokia's Here mapping technology. Autoblog's Eddie Sabatini reports on this edition of Autoblog Minute. Show full video transcript text [00:00:00] In a battle for Nokia's highly coveted mapping technology the auto industry claims victory over Silicon Valley. I'm Eddie Sabatini and this is your Autoblog Minute. In a three company partnership the German automakers BMW, Audi and Daimler are set to take ownership of Nokia's Here mapping technology. The Wall Street Journal writes that the automakers had concerns that the technology might fall under the [00:00:30]control of companies like Google, Uber, or Apple. The purchase, worth a reported 3.1 billion dollars, is still subject to antitrust evaluation before it's finalized; but this early news is already a big win for the German three. Ownership of Nokia's Here tech means that automakers won't lose control of the information systems that go into their cars. The deal, if approved, is expected to close in first quarter of 2016.
