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.

A8 Audi Exclusive Concept shows off brand's interior chops

It's an envious position to be in, not wanting a normal Audi A8 but not wanting to make the statement that comes with a Bentley or a Rolls-Royce. What's an oligarch to do? Well, if you have the funds, consider the A8 Audi Exclusive Concept (yes, that's the actual name), a modified A8L W12 that's limited to just 50 units and features a significantly upgraded interior. Think of it as a followup to the A8 Exclusive Concept, shown at Frankfurt in 2011.
Aniline leather from Italian furniture manufacturer Poltrona Frau is fitted over the seats, while diamond stiching accentuates the Agatha Cognac color. Granite Gray piping and stitching on the seats provides some contrast - not just with the leather but the natural, olive ash inlays on the dash. Granite Gray Nappa leather lines the instrument panel and steering wheel while a white Alcantara headliner sets off the whole package. Not that it's a shock, but this looks like a really nice place to spend some time.
It's unclear how much the exclusive concept treatment adds on to the already lofty $135,900 starting price of a US-spec A8L W12, or if the special interior treatment will even be available in the North America. Production is set to kick off next March. Scroll down for the full statement from Audi.

Audi S8 makes cameo in commercial about cameos with Stan Lee

Stan Lee is the undisputed king of the cameo. The 92-year-old comic scion makes a brief appearance in every film Marvel Studios produces, of course, but, according to IMDB, that's just the beginning. Lee has an impressive 84 credits to his name, with such standout characters as Man on Bench, Hot Dog Vendor, Distinguished Bystander, Milwaukee Man Drinking From Bottle, Rejected Wedding Guest, Waterhose Man, and Hot Dog Vendor (again). Building on Lee's well-known acting success, Audi has introduced a humorous video in which its own S8 sedan makes a cameo, as do Tara Reid, Michael Rooker, Lou Ferrigno, and Jason Mewes. It's all part of the Avengers: Age of Ultron launch, which Audi has helped promote for the last few months.
