Turbochargers, like acoustic guitars, use moving air to create magic. And electric turbochargers, like electric guitars, provide the ability to amp up that magic to amazing new levels.

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.

VIDEO TRANSCRIPT [00:00:00] Hi, all. This is Seyth with Autoblog. I'm here driving the 2015 Audi S7. I'm caught in a kind of annoying, normal, end-of-the-work-day suburban traffic right now, but even that helps to illustrate the point that I'm trying to make about the S7, is that it really is one of the best all-around grand touring cars that you can buy. A really, really good grand tourer has to do three things. [00:00:30] One, it has to look amazing. It has to feel really special inside and out. The second part is that it's got to be a great long-range cruiser. It needs to be powerful on the highway, be able to be very comfortable and quiet if you're taking it long distances, kind of like your typically Autobahn car. Three, and I think this is really difficult with the second one that I mentioned, I think that grand tourers have to be really great at driving like sports cars. [00:01:00] You're going along and you're touring on the highway and you know that a really great road is coming up. The car should be able to get off on that road and handle like something much lighter and still have that great cruising character. That's one of the reasons why I've always liked the entire Audi A7 line, but especially this S7 because the A7 itself in all of its guises is really a pretty great cruiser and a really practical all-around car with the space in the hatch [00:01:30] and reasonable room in the back seats. The S7 with the turbocharged 4.0-liter V8 making 420 horsepower and 406 pound-feet of torque really amps up the sportiness. Now don't get me wrong, the S7 is far from a sports car. It's not very light. It's got a long wheelbase. It is nimble, especially with Quattro, but it doesn't feel especially nimble. It doesn't want to change directions super quickly. It splits the difference between the two. That being said, [00:02:00] when you get up to some of your favorite roads, it doesn't disappointment you either because of all the power and grip and some pretty decent sporting character available. Of course one thing that you do lack in a big GT like this S7 vs.
