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:

Audi RS3 spy shots foreshadow an ultra-hot hatch

Not all vehicle prototypes and mules require heavy camouflage - sometimes they can be hidden in plain sight. That's probably what Audi was hoping for while testing its new RS3 wearing S3 duds, but thanks to some visual and audible telltales, our spy photographers were able to recognize this as a precursor to the marque's ultra-hot hatch testing near the Nürburgring.
Our photographer noticed the signature exhaust note of a five-cylinder engine, which suggests the RS3 could borrow its motivation from the excellent TT RS. Producing at least 340 horsepower, this 2.5-liter turbo powerplant could be the perfect answer for the new A45 AMG from Mercedes-Benz. The big brakes on this RS3 mule give us our best idea about the car's high-performance intentions, with Audi RS wave brake rotors and six-piston calipers peering out from behind the oversized wheels.
In production form, the RS3 should have a much different appearance from what you see here, with sportier design cues including oval-shaped dual exhaust outlets and a more aggressive front fascia. While we're still waiting for our first taste of the S3 in the North America, we'll be holding our breath for the RS3 to make its way here, as well.

2013 Audi S3

Coming Soon To Our Shores With Two More Doors And A Trunk
The Audi S3 is not exactly a sales juggernaut, despite it being a bit of a legend for passionate fans of the small German premium genre. In most markets outside of Europe, people may consider such setups as the S3 three-door tested here, look at the price, and then think maybe they should just get a nice A4 sedan with greater practicality for similar cash. That certainly has been one reason Audi has never officially brought the S3 hatchback to the United States. And the 335-horsepower RS3 Sportback? Forget about it nearly everywhere but in Germanic regions, Switzerland and the UK.
All of which automatically turns the new S3 hatchback into an unattainable object of desire for many fans of the four-ringed brand. The good news, of course, for many markets not on the three-door or S3's dance card is that most of us will get a shot at buying the new S3 sedan that will be powered by the same drivetrain tested here. We reported heavily on the sedan version from the recent New York Auto Show and are convinced that there is much for North American shoppers to like.
