Autoblog gets ready for Le Mans with an R8 road trip and Allan McNish

This car is the master link between what Audi does on the race track and sells on the road.
We're attending the 24 Hours of Le Mans with Audi and we figured we'd make the world's biggest endurance race even more interesting by driving from Munich to Le Mans in an R8. We've also had a brief chat with Audi driver Allan McNish, and if you haven't already, check out all the multimedia ways to enjoy the next four days from the Circuit de la Sarthe, then read on.

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 Q3 production begins in Spain

2012 Audi Q3 - Click above for high-res image gallery
It wasn't that long ago that Audi had no SUVs in its lineup - aside from the A6 Allroad Quattro - despite being known for its all-wheel-drive vehicles. But that's all changed, just as it has for BMW and Porsche. The Q7 was followed by the Q5, and now the Q3 has started production as well.
The first Q3 rolled off the assembly line today at the plant in Martorell, Spain. The facility belongs principally to Audi's sister-company Seat, but has gone through a considerable expansion - funded by both Audi and Seat - to prepare for the Q3's production.
