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 reveals revised RS5 DTM for 2014

There existed an era in German touring car racing between when the DTM series was revived in 2000 and when BMW rejoined in 2012. During that twelve-season span, the wins were pretty evenly divided between Audi and Mercedes-Benz, the only two manufacturers who took part. Audi won six drivers' titles in that time and Mercedes won six (although Benz won considerably more constructors' titles).
Now that BMW is back in the race, though, it's an entirely different game. BMW has won the lion's share of the races in the past two seasons, taking both titles in 2012 and the constructors' title last season. The winning driver last season, though, was driving the RS5, making Audi the only one that really stands a chance of putting up a fight against BMW. It undoubtedly hopes to extend that challenge in the coming season, and this is the car with which it aims to do so.
Taking on the Mercedes-AMG C-Class Coupe DTM and the new BMW M4 DTM will be the revised RS5 DTM you see here. Bearing a stronger resemblance to the road-going RS5 you can buy, Audi's new DTM challenger benefits from a revised aero package with more streamlined side mirrors, closed rear wheel arches and reprofiled side sills. The V8 engine carries over (much as it did from the previous A4 DTM and A5 DTM) with 456 horsepower driving the rear wheels through a six-speed sequential gearbox.

Audi reveals updated RS7 Sportback in Europe

It was just a couple of weeks ago that Audi revealed a few mild updates to its A7. It even ported those changes over to the warmed-up S7 performance version. All that was missing was the full-steam RS7, and that's precisely what we have here.
Now before you get all excited, note that the new RS7 packs the same powertrain as the model it succeeds, but then again, the existing RS7 hardly lacked in the power department. The 4.0-liter twin-turbo V8 still churns out 560 horsepower and 516 pound-feet of torque, transmitted to all four wheels through an eight-speed automatic. Revealed initially for the European market (with US details presumably to follow), the 0-62 kilometers per hour time is quoted at 3.9 seconds, so the 0-60 mph time ought to match the 3.7 seconds of the preceding model.
What has changed are the subtle tweaks Audi has made to the exterior and equipment upgrades inside. The grille now features has a horizontal section at the bottom with the Quattro logo emblazoned across like all other recently revised RS models, flanked by new headlights (Matrix LED units for the European market). Inside the cabin the air-con vents and shift paddles have been reshaped, and the new MMI system ports over from the new A7 and S7 with 4G LTE connectivity and a Bang & Olufsen sound system.
