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 RS4 Avant Nogaro Selection puts a fresh face on old memories

I've been fortunate enough to drive plenty of memorable cars over the years, and one of my all-time favorites is the Audi RS4 sedan. It was only sold in the United States for a short time, but during that quick run, it made a huge impression on me. I remember everything about that car - the smell, the sound, the exact feeling of the manual shifter as it clicked between the six gears, and the texture of the steering wheel that I so happily tossed about. In fact, whenever I'm feeling nostalgic, I go back and watch this video of the late David E. Davis, Jr., running the California Mille roads in a Sprint Blue RS4 - a video we shot for Winding Road many years ago during my tenure as an editor there.
So even though the Audi RS4 Avant Nogaro that debuts here in Geneva isn't super important, especially for our American-centric audience, I feel compelled to write about it. No, we don't get the lovely RS4 in the States anymore, but the package offered in Europe is just as sweet as ever - perhaps even more so, what with that stylish longroof shape. Under the hood is Audi's excellent, naturally aspirated 4.2-liter V8 engine, tuned to deliver 450 horsepower and 317 pound-feet of torque, allowing for a 0-62 sprint of 4.7 seconds.
The Nogaro name refers to the special blue paint - a throwback to the original Audi RS2 Avant that kicked off the company's super sweet luxury offerings. Other unique features for the Nogaro car include gloss black exhaust outlets, window frames and grille surround, as well as matte black roof rails. Special 20-inch wheels round off the exterior enhancements, and inside, Nogaro Blue Alcantara accents can be had on the door panels and seat inners.

Audi considering turbo option for longer, wider Hurac?n-based R8

The debut of the Lamborghini Huracán was (and remains) big news in and of itself, but equally as exciting is the imminent arrival of the Audi R8, which the Huracán presages. While the two will share a common architecture, don't expect that new R8 will simply be a cheaper version of the Huracán (like the current one arguably is to the Gallardo).
For one, the next R8 will be larger than the Huracán. According to emerging intelligence, Audi will make its sports car both longer and wider than the Lamborghini version. It'll also share the new Lambo's innovative carbon-fiber structure that will replace both the firewall and central tunnel. But to power it all, Audi will get more creative.
The next R8 will, like the current model and like the Huracán, offer a V10 engine at the top of the range. It will also offer the same 4.2-liter V8 as the outgoing model. But that won't be the end of the matter. Word has it that Audi is also working on a smaller, turbocharged engine to offer in certain markets that mandate smaller-capacity engines.
