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 A3 G-Tron offers big range, few emissions

Audi is exploring a variety of sustainable transportation technologies beyond the traditional diesel, hybrid, plug-in and electric options, including the compressed natural gas A3 Sportback G-Tron that debuted today at the Geneva Motor Show.
The most interesting thing about this rather innocuous-looking A3 Sportback is that when run on Audi e-gas, the car becomes completely carbon neutral, emitting no more CO2 than was chemically input in this special fuel's production. Audi has already broken ground on a new plant - powered by renewable energy, of course - that uses electrolysis to produce e-gas, which could then be made available through any natural gas distribution network.

Next-gen Audi A5 shows its heavily camouflaged face

The new Audi A4 is set to launch at the Frankfurt Motor Show in September, so it shouldn't come as too big of a surprise that an updated A5 is on the way, as well. Our spies just caught the coupe testing for the first time while wearing heavy camouflage from nose to tail. Despite the concealment, some details are possible to make out, especially when comparing the two-door design to the previously spied A4. Audi is further differentiating the designs, and the A5's front end is significantly changed based on these photos. The headlights appear larger and more acutely angled than the narrower units on the sedan. Also, the lower bumper gets square intakes at each corner and the shape creates an additional opening in the center for the coupe. In profile, it's easy to notice the quicker sloping roof and smaller side windows. Only the rear end of the two models seem to share many significant cues. The new A5 reportedly rides on the same MLB Evo platform as the upcoming A4 to shed around 200 pounds. The two models might not launch at the same time, though, and the coupe could join the lineup somewhat later. S5 and RS5 variants are expected to join the range further down the line, too.
