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.

Audi teases 700-hp Quattro Sport E-Tron concept for Frankfurt

Audi's trump card for the 2013 Frankfurt Motor Show has just been unveiled, sort of. It's called the Quattro Sport E-Tron Concept. Set to debut in a few weeks, sketches have been uncovered that show a few of the car's details, albeit in rough form. The news of a big-name Audi concept at Frankfurt has been swirling since June, when we first reported on it.
From the sketches, we see a car that has the same basic shape as the Quattro Concept from the 2010 Paris Motor Show, only with subtle tweaks and evolutions to a few features. The news isn't so much about the looks, though. It's the reports coming from Auto Zeitung and Audi enthusiast site Fourtitude.
Horsepower on the concept is expected to be in the neighborhood of 700 ponies - about 50 more than we initially thought - and will be split between a gas engine and an electric motor. Yup, that "E-Tron" name isn't just there for show. While it's not clear what the exact split will be between gas and electric power, we do know the same twin-turbo 4.0-liter V8 found in the RS6 and RS7 will be sitting under the Quattro's hood, and that the bulk of the power will likely come from here. We may not have power figures on the hybrid system, but we do know this concept is capable of running for 21.7 miles on electric power alone.

Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:
