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.

Watch two Audi RS4 Avants play Death Race with paintball

Nothing to see here, folks, except a 2013 Audi RS4 Avant weaponized with a high-caliber paintball canon. No, make that two of them, one black and one white, playing paintball in an abandoned aircraft hangar. At this point, there's probably not more to add than "Watch the video below" while we get on the horn to find out how to get this as a factory option. And the wagon itself, since that's not coming here, either...
But what's cooler than two high-powered Audi wagons with paintball guns and push-button firing in a video set to cheesy music from a bad eighties rip-off of Top Gun? One car can dump paint out of spigots under the rear bumper, the other has paintball grenades. And now we've really said enough. So watch the video, and the two behind-the-scenes vids, below.

Automakers teaming with Google to bring Android to cars this year

Remember how we mentioned that Hyundai would be offering a BlueLink infotainment app for Google Glass? And how last week, we told you about a rumored partnership between Audi and Google? Well, both of these things were just part of a much bigger deal.
Google has teamed up with Audi, General Motors, Hyundai and Honda to form the Open Automotive Alliance. With the help of chipmaker NVIDIA, the group aims to bring Google's Android operating system to the auto industry on a large scale. While the speed with which Android will be adopted by the industry remains unclear - the OAA's own press release says "timing for each automaker will vary" - we could see the first Android-equipped vehicle by year's end.
For those that keep their ear to the ground in the automotive tech world, this is a big deal for more than just one reason - Honda, GM and Hyundai are all partners in the Siri Eyes Free program from Apple. The future of that relationship now that three of its automakers are in bed with Apple's arch-rival, though, could be under threat.
