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.

Audi A7 getting nip and tuck

It's been less than two years since the Audi A7 first went on sale in the US, but European buyers have been able to enjoy the sleek and stylish hatchback for twice as long. As such, Audi is preparing to give its A7 a mild refresh with tweaked exterior styling, but we're also expecting some of the features found in the all-new 2015 Audi A8 to possibly trickle down to the A7.
From what we can tell in these spy shots, the A7 is getting a minor facelift that includes a restyled front fascia and new headlights, which will likely boast Audi's new Matrix LED system. At the rear of the car, similar changes have been made with a fascia that now gets integrated outlets and different taillights that have a Lamborghini-like display.
Not apparent in these images - but still a good bet for production - we'd expect to see the new A7 get some of Audi's updated engines or new driver assist technologies. No definite word as to when we'll be seeing the refreshed A7 in person, but considering how close to production ready as this car seems to be, our bet is on the upcoming Geneva Motor Show.
