Audi moves to patent electric Quattro and active-shutter wheels

Audi might have a few tricks up its sleeve for the coming years, with the Brits at Autocar uncovering a pair of patent filings made by the German luxury brand. The first is something we've seen before - wheel flaps - while the second is an evolution of one of Audi's trademark technologies.
We last saw wheel flaps on the Ford Atlas Concept in 2013, but the futuristic fuel-saving tech has so far failed to arrive on a production car. Audi may be seeking to change that, patenting the flaps that open and close automagically based on airflow. They can also open if the brakes get too hot.
The second patent is an evolution of Audi's Quattro all-wheel drive. The new AWD system uses an electrically driven rear axle and wheel sensors to figure out when and at which corner the car might lose traction, and is targeted largely at hybrid offerings, which is a field Audi has only recently dipped its toe into.

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.

24 Hours of Le Mans live update part two

We tasked surfing journalist Rory Parker to watch this year's live stream of the 2016 24 Hours of Le Mans. What follows is an experiment to experience the world's greatest endurance race from the perspective of a motorsports novice. Parker lives in Hawaii and can hold his breath longer than he can go without swearing. For Part One, click here. Or you can skip ahead to Part Three here. I write about surfing for a living. If you can call it a living. Basically means I spend my days fucking around and my wife pays for everything. Because she's got a real job that pays well. Brings home the bacon. Very progressive arrangement. Super twenty first century. I run a surf website, beachgrit.com, with two other guys. It's a strange gig. More or less uncensored. Kind of popular. Very good at alienating advertisers. My behavior has cost us a few bucks. I'm terrible at self-censorship. Know there's a line out there, no idea where it lies. I still don't understand any of the technical side. Might as well be astrophysics or something. For contests I do long rambling write ups. They rarely make much sense. Mainly just talk about my life, whatever random thoughts pop into my head. "Can you do something similar for Le Mans?" "Sure, but I know absolutely fuck-all about racing." "That's okay. Just write what you want." "Will do. But you're gonna need to edit my stuff. Probably censor it heavily." So here I am. I spent the last week trying to learn all I can about the sport of endurance racing. But there's only so much you can jam in your head. And I still don't understand any of the technical side. Might as well be astrophysics or something. While I rambled things were happening. Tracy Krohn spun into the gravel on the Forza chicane. #89 is out of the race after an accident I missed. Pegasus racing hit the wall on the Porsche curves. Bashed up front end, in the garage getting fixed. Toyota and Porsche are swapping back and forth in the front three. Ford back in the lead in GTE Pro. #91 Porsche took a stone through the radiator, down two laps. Not good. The wife and I are one of those weird childless couples that spend way too much time caring for the needs of their pet. French bulldog, Mr Eugene Victor Debs. Great little guy. Spent the last four years training him to be obedient and friendly. Nice thing about dogs, when you're sick of dealing with them you can just lock 'em in another room for a few hours. You don't need to worry about paying for college.
