Felix Baumgartner parachutes into racing at N?rburgring 24

There are plenty of commonalities to be found between astronauts and racing drivers. Both are daredevils by definition (if not by trade), both subject themselves to unfathomable G forces and both face very real risks when strapped into machinery that makes the very best use of advanced propulsion, aerodynamics and composite construction technologies. Yet you don't find much crossover between the two. There was talk of Niki Lauda, himself an experienced pilot, training to go into space with Virgin Galactic (which itself was sister to an F1 team for a while in Richard Branson's empire), but that didn't seem to materialize. Now we're receiving news that Felix Baumgartner will contest the Nürburgring 24 Hours this year.
Felix Whomgartner, you ask? Felix Baumgartner. He's more of a skydiver than an astronaut, but he made history in 2012 when he jumped out of a space capsule and set the record for the highest altitude in a manned balloon, the parachute jump from the highest altitude, and the highest velocity freefall as part of the Red Bull Stratos initiative. In other words, he may as well be an astronaut, because he fell down to the earth's surface from the stratosphere.
For his next challenge, Baumgartner will be climbing into an Audi R8 LMS Ultra in an attempt to tackle the Nürburgring. Having contested a handful of spec races under the VW Group umbrella, he'll undertake several test sessions and practice races before the main event in June, in which he'll alternate behind the wheel with professional racing drivers Frank Biela, Marco Werner and Pierre Kaffer. The initiative is part of the Audi race experience program that allows gentleman racers to team up with seasoned pros to take part in real races. Baumgartner will undoubtedly prove its highest-profile participant.

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 RS6 Avant vs. Vauxhall VXR8 Supercharged in wagon battle

The performance station wagon is the mature person's muscle car. As we get older, it's natural to add things like spouses, kids and dogs to our lives and each one necessitates a little more space. That doesn't mean we want to give up spirited driving though, and a quick five-door offers a great balance between needs and wants. In the latest video from Evo, we take a look at two, muscular European estates to see which is faster around a track.
Richard Meaden pits the Audi RS6 Avant and Vauxhall VXR8 Supercharged against each other; seeing that the cars go about utilizing their massive performance in very different ways. The RS6's all-wheel drive and luxury interior make it more of a scalpel around the track compared to the Vauxhall's rear-wheel drive hammer. Both offer the driver the chance to create some very smoky powerslides, though. Sadly, neither of these muscle wagons are available in North America, but scroll down to get a taste of them in the video.
