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.

Audi's latest design is a table clock

Audi and Porsche have more things in common than we can count. They're both German, of course, and have both enjoyed considerable winning streaks at Le Mans. Both have a tendency to put their (often turbocharged) engines at one extreme of the car or another, driving either the closest wheels or all four. Both tend to follow a brand-wide evolutionary design approach, focusing their energies instead on the engineering that goes under the bodywork. Both now find themselves under the same corporate umbrella, and now that they are, Audi has followed Porsche's lead in setting up its own design consultancy.
Like Porsche Design, Audi Design is now taking on projects for all manner of clients, from pianos to foosball tables. In this latest collaboration, Audi has designed a table clock for Munich-based watchmaker Erwin Sattler. The table-top clock houses a high-frequency mechanical movement in a foot-tall glass case that lets you see the intricate clockwork, held in place by two ruthenium clasps.
Unveiled in Switzerland at the Baselworld watch and jewelry show, the clock is now available to order. But while prices haven't been announced, don't expect it to come cheap: other Erwin Sattler table clocks typically sell for upwards of $10,000, and we wouldn't expect the new design to come at a discount.

Audi A5 and S5 freshen up for 2017

UPDATE: A previous version of this story mischaracterized the 2017 S5's engine configuration. The article has been updated. Well, here's the new Audi A5 and S5. They look a lot like the old ones, but just a tiny bit better. In other words, the redesigned coupes received the same treatment as their four-door counterparts, the A4 and S4. While the German press materials mention both gas and diesel engines, we expect the A5 to carry on in the US with petrol power only. Like the current A5, a 2.0-liter, turbocharged four-cylinder will serve as the base engine, but will probably get a similar power bump as the A4 – Audi hasn't released official figures yet. The four-door had its base output bumped from 220 horsepower and 258 pound-feet of torque to 252 hp and 273 lb-ft of torque. The S5 is a more interesting proposition than the S4. Where the old S5's 3.0-liter, supercharged V6 produced 333 hp and 325 lb-ft of torque, the new, turbocharged, 3.0-liter six-cylinder pumps out 354 ponies, according to the global press materials. That figure, fans of the old 4.2-liter V8-powered S5 will note, is identical to the original S5 that came out for model-year 2008. Torque figures aren't available yet, but we'd bet on at least a small increase in torque. Still, the increase in power is good for a 4.7-second run to 62 miles per hour, a 0.2-second improvement over the current car's 0-60 time. Audi claims it will offer the A5 with both six-speed manuals and seven-speed dual-clutch transmissions, but we wouldn't be so sure about that stick here in the US. The only available gearbox on the A4 is a seven-speed S-Tronic – coupes are inherently more sporting than sedans, but we aren't sure that's justification for Audi to offer a manual-trans A5 here in the US. Audi only mentions an eight-speed automatic for the S5. So no, the German press materials aren't a good indicator of the US-market A5. What we can rely on, of course, are the official images. The original A5/S5 was a handsome car, but Audi's designers have done a swell job styling the 2017 model. It looks good, and is somehow even more refined than last year's car. Audi's new corporate grille works well on a coupe body, although the powerful creases in the hood might be a little too powerful. The tail is lovely, like a prettier A3. The bodies are better looking, but they're also lighter and more aerodynamic, too. The A5's coefficient of drag is down to a slippery 0.25, while Audi's engineers lipo'd 132 pounds of fat.
