Audi RS7 prototype is world's sportiest self-driving car [w/video]

Audi may not be the only automaker out there toying with self-driving automobile technology, but it is arguably the fastest of them. A few years back, it raced unleashed a driverless TTS on the Bonneville Salt Flats, then sent it up Pikes Peak and around Thunderhill. But now it's taking things a step further with the vehicle you see here.
This RS7 Sportback has been fitted with steering, brakes, throttle and transmission hooked up to a computer system that combines GPS, high-frequency radio signals and 3D imaging camera to drive the vehicle autonomously not just in slow-paced, stop-and-go traffic, but around the track at the same pace a professional racing driver would push it: full throttle on the straights, full braking before the corner and 1.1-g of cornering force.
As promised, Audi plans to unleash the self-driving RS7 - which it calls "the sportiest piloted driving car in the world" - at Hockenheim next weekend prior to the DTM season finale, where it is anticipated to pull a 2:10 lap time. The next stage will be to set it lose on the Nürburgring Nordschleife, all 154 turns and 13 miles of it, which ought to pose a heck of a challenge to the engineers from Ingolstadt. In the meantime you can scope it out in the high-res image gallery above and the second teaser video below.

How does a 600-HP Audi RS6 Avant Plus sound to you?

The 2013 Audi RS6 Avant was announced back in December with a twin-turbo V8 cranking out 560 horsepower, but Car is reporting that this badass grocery getter could get even more power with a new Plus model. In a conversation with Car, Stephan Reil, Audi's top guy at its Quattro GmbH division, told the magazine that the RS6 Avant Plus would produce around 600 horsepower, and it sounds like there is a growing family of RS Plus models being planned as well.
Aside from the more powerful engine, the specifics of the RS6 Avant Plus are unknown, but we'd suspect some weight-savings measures and updated features for improved handling. Like recent RS Plus models such as the TT RS Plus and R8 Plus, the RS6 Avant Plus will not be a limited-production unit when it goes on sale (most likely for the 2014 model year).

Audi Traffic Light Assist helps you hit every green light

Before taking a ride in Audi's impressive Piloted Driving A7, we took a short spin up and down the Las Vegas strip to check out a smaller, but intriguing piece of Audi driver assistance technology called Traffic Light Assist that promises to help drivers make every green light.
Using both live and predictive data beamed into the vehicle's navigation unit via onboard wifi, TLA doesn't need a single camera to tell you when the light is going to change. Local data sources provide information about traffic light patters, and the in car system uses that data and the motion of the car to predict exactly how long it'll be until the green light goes red.
In practice, the system shows a traffic light icon in the central display (a head-up display would be a nice option), along with a countdown timer that reads the number of seconds before a light changes from red to green. Additionally, the system corrects (nearly instantly in our demo) for changing lanes and resultant changing signals; changing a straight-through traffic lane to a left-turn lane and signal, for instance.
