Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

Audi replaces Mercedes as official vehicle supplier to the IOC

The automotive sponsor of the International Olympic Committee for the past 22 years has been Daimler-Benz. No more, as Audi has just signed a four-year deal to be the official auto supplier to the folks who keep the torch alight and on the move. Audi will supply vehicles for the IOC's headquarters in Lausanne, Switzerland and the organization's international events.
In case you're remembering all the stories about BMW and the London Olympics last summer and wondering where Mercedes-Benz was in all of that, the answer lies in the numerous mouths at the Olympic trough. The IOC is the organization and oversight body of the Olympics - much like the way the FIA oversees world motorsport. BMW, though, sponsored the London Organizing Committee for the Olympic Games, so during the games IOC reps rode in Benzes, LOCOG and its guest dignitaries rode in BMWs.
The Volkswagen Group has other ties with the Olympics as well: The Group will be the official vehicle partner for the winter Olympics in Sochi, Russia in 2014, and Audi currently partners the national Olympic federations of Germany, Finland, Russia and Switzerland. The press release below announcing the partnership has all the official details.

Audi to enter third R18 following Loic Duval's huge crash

When we saw the picture above yesterday, our first thought went to driver Loic Duval. After hearing that he, miraculously, walked away from the annihilated heap that had been the number one Audi R18 e-tron Quattro, our next thought went Audi's hopes in this year's 24 Hours of Le Mans. With the race kicking off on Saturday, we couldn't be sure if the team would run a two-car effort (that would put them on even footing with the two-car teams of Porsche and Toyota), attempt to rebuild the decimated racer or bring in a new tub and start from scratch.
Turns out, Audi opted for door number three, importing an all-new chassis to replace the destroyed R18. According to Audi, the team pulled an all-nighter to ready the new car in time for scrutineering and the second round of qualifying.
