Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.

2017 Audi Q7 Second Drive

One morning, I'm driving down the Malibu coast, top-down in a two-seat sports car. Twelve hours later, I'm on a straight road, in traffic, and piloting a seven-seat SUV. I think this is how new parents feel. There's no other word but "parental" to describe how three-row crossovers, like this 2017 Audi Q7, make me feel. Whether it was the Honda Pilot that was actually kind of tossable, or the plush Kia Sorento, one glance in the rear-view mirror at five headrests makes you wonder if someone isn't waiting for you outside an elementary school. The Q7, however, has always been a luxury car first. And this second-generation model is crammed with technology and convenience features to make life more effortless, as if it was designed for a person who lives in Bel Air but also must take the kids to horse-riding lessons on the one weekend it rains in Southern California. Autoblog already tested a European example, but I'm now getting the chance to finally drive it Stateside. When it comes to the Q7's appearance, I always seem to have a minority opinion. The old one looked like a bus when plenty of people said it looked beautiful. This new one has been widely criticized for looking like a wagon, but I don't see a lot wrong here. At some angles, it's reminiscent of the old 5000 Avants from the '80s – probably not a coincidence, since the Q7 is Audi's most prestigious wagon right now. Even Audi admits it pulled from the '80s with styling cues along the rear quarter panels and the ever-larger "Quattro" badges. While the shape grows on you, it isn't going to stop people seeing it and thinking it's a Q5. The new Audi Q7 has an incredible sense of elegance about it. The most ambitious design touches are the arrows in the LED lights, front and rear, but they're ultimately dwarfed by the size of the car. What's more, the string of white, silver, and gray cars on hand at our test aren't exactly striking, and the optional 20-inch wheels are boring in design. You could also call this "quiet luxury." Or perhaps stately. The new Audi Q7 has an incredible sense of elegance about it, never feeling ponderous like a truck and always feeling secure like a large luxury sedan. As the first application of the Volkswagen Group's MLB Evo platform, it really is a large luxury wagon. Which is the exact image the company seems to be running from.

The Audi RS5 takes aim at the BMW M4 and Mercedes-AMG C63

The current generation of the Audi A5 has soldiered on for the past 10 years, an eon when it comes to automobiles. Though we've seen and driven its replacement, the new car hasn't quite made it to market. As with most of Audi's lineup, the car is expected to come in three versions. While the full reveal and first drive reviews of the A5 and S5 took place late year, until now we haven't had a peek at the range topper Audi RS5. It sits on Audi's B9 platform shared with the Audi A4 sedan. Essentially, it's Audi's equivalent to the BMW 4 Series or the Mercedes-Benz C-Class coupe. In the case of the RS5, compare it to the BMW M4 and the Mercedes-AMG C63. Like its rivals, the RS5 sits longer, lower, and wider than its sedan stablemate. The RS features aggressive front and rear fascias and a set of unique wheels. While the styling of the new model may look evolutionary, it is indeed all-new inside and out. The two cars in these photos are wrapped in camouflage that covers everything below the beltline. The general shape of the bodywork looks the same, but the front and rear are slightly restyled. The front now has larger air intakes in the corners and a lower chin spoiler. Out back, the dual single-exit exhaust pipes give the RS model away. The S5, like all S models, features quad exhaust tips. The rear bumper is slightly modified, but all in all it's not far off from the A5 and S5 models. Audi's styling is always conservative, so this should come as no surprise. There's no word as to what's resting under the hood, but look for forced induction and six cylinders, possibly pulling something from the Porsche Panamera. As with every other Audi performance car, power will be sent to all four wheels through the latest generation of the Quattro all-wheel drive system. Look for a full reveal in the next few months, possibly as soon as March at the Geneva Motor Show. Related Video:
