Audi welcomes Porsche back to Le Mans like any sibling would

Ah, sibling rivalry. It really is a beautiful thing. It's even more beautiful when said siblings are automakers with very, very well-known racing histories. That's how you get videos like this, which is Audi's way of welcoming Porsche back to the top flight of Le Mans racing.
Yes, Audi has taken its R18 E-Tron Quattro back onto public roads, wowing schoolboys and scaring farmers (who appear to be riding classic Porsche tractors), as it travels from Ingolstadt to Zuffenhausen, just to taunt its corporate frenemy.
Take a look below for a video to see just what that teasing looks like.

Audi also calling in A8, S8 over sunroof issue

The S6 and S7 (apparently prone to potential fuel leaks) aren't the only Audis being recalled currently, as a separate recall notice has been issued for its flagship A8 luxury sedan and its high-performance counterpart, the S8.
The problem apparently revolves around the glass sunroof, which is fitted as standard and which is reportedly prone to break. The National Highway Traffic Safety Administration determined that not only could the falling shards themselves end up injuring the vehicle's occupants, but could also distract the driver enough to cause a crash. As a result, Audi's American wing is bringing in all 2013 and 2014 model year A8s and S8s - 1,120 units in all - to have their glass sunroofs replaced free of charge.

New Audi Quattro concept coming to Frankfurt?

We first saw the Audi Quattro Concept at the 2010 Paris Motor Show, and since then we've been tugged this way and that by a series of rumors as to whether the car will be built or not, and whether such a car will live at the accessible or the exalted end of the cost spectrum. A report in Germany's Auto Zeitung from June restarted the fires of gossip with a report that a production version of the concept will appear at the Frankfurt Motor Show, and put it firmly in the exalted sphere.
Now, just a month from the show, Auto Bild has a similar report, sketching out an upmarket car but on a different platform. Back when we drove it, the Quattro concept was built on a spaceframe based on the RS5 platform and got its go from a 2.5-liter five-cylinder engine with 380 horsepower and 354 pound-feet of torque (the show car got 408 hp from a turbocharged five-cylinder). The June report from Auto Zeitung said this new reveal would be powered by a modified version of the twin-turbo 4.0-liter V8 from the RS7 that would put out something like 650 hp. Auto Bild, on the other hand, reports that the engine will be tuned to something like 600 hp and the new concept will ride on an "enhanced" version of the A6 platform.
Both reports agree that the car we'll see will preview Audi's new design language with "tauter, more angular lines." Lightweight and exotic materials will be used in efforts to reach a supposed target weight of 1,200 kilograms (2,640 pounds), down from a target of 2,900 pounds in earlier report. Auto Bild says that Audi still hasn't decided whether to make a production version, but if they are correct about the direction of the concept, any retail offering based on it isn't going to be cheap.
