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.

Electric turbos promise big performance and efficiency gains in the near future

An electric turbo system boosts efficiency between 15 and 20 percent, according to Audi.
Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

Audi reveals virtual reality 'dealership in a briefcase'

Virtual reality still seems like technology that should be lumped in with the flying car and colonizing the moon as the sort of perennially "almost-here" Next Big Thing that never quite arrives. However, devices like gaming's Oculus Rift suggests that it's too soon to write off VR just yet, and Audi apparently agrees. The heart of its new VR Experience is a headset that customers wear that lets them see a virtual car before their eyes. Using the technology, the potential buyer can sit behind the wheel or open up the trunk. A camera tracks their head movements and adjusts the image on the goggles accordingly. To make the whole experience even more immersive, headphones let them hear the sound of the door or listen to the radio. The German automaker claims that the VR Experience technology will be available in "dynamic growth markets" by the end of 2015. The system will essentially offer the entire dealership experience in a device the size of a briefcase, and it'll be possible to view every possible equipment combination and color on all of the brand's models. The immersive hardware sounds amazing, if it's as good as the automaker claims. Among other things, VR will allow buyers to pick out just the right color and trim, even if the dealer doesn't have that specific combo in stock. Read below for Audi's announcement of this sci-fi gadget that the company claims is on the way. Audi VR experience: the dealership in a briefcase Innovative virtual reality headset extends advisory service at Audi dealers Sales chief Luca de Meo: "Further proof of Audi's pioneering role in sphere of digitization" First Audi dealerships to introduce new sales tool by end of 2015 Audi is taking the next big step in integrating digital technologies into automotive retail: The Audi VR experience gives customers the opportunity to configure their preferred car at the dealership through virtual reality headsets and experience it in a unprecedentedly realistic way. The headset showcases the entire model portfolio of the four rings, including all possible equipment combinations. Audi has become the first automotive manufacturer to develop a dedicated retail software solution for virtual reality headsets.
