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.

VW Group recalls 27k Touaregs, Audis and Porsches for fuel leak

The Volkswagen Group is one of the most expansive in the entire industry, and shares parts across more product lines than we could wrap our heads around. So when the German megalith finds a fault in one of its components, it has the capacity to spread like wildfire. The latest set of recall notices from the National Highway Traffic Safety Administration covers vehicles from the Volkswagen, Audi and Porsche divisions. The problem revolves around the fuel injection system, which could potentially leak and cause a fire. The recall affects – deep breath now – the 2012 VW Touareg Hybrid, the 2011-12 Porsche Cayenne S Hybrid and Panamera S Hybrid, 2011-12 Audi S4, S5 and Q7 and the 2012-13 Audi A7. All told, that amounts to 27,376 units, the owners of which can expect to hear from the manufacturer to have the fuel rails replaced, along with their corresponding seals (having nothing to do with marine mammals writing letters). RECALL Subject : Fuel Injection System Fuel Leak Report Receipt Date: JAN 20, 2015 NHTSA Campaign Number: 15V019000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 26,008 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2011-2012 Audi S4, S5, Q7, 2012 Audi A6, Volkswagen Touareg Hybrid, and 2012-2013 Audi A7 vehicles. In the affected vehicles the fuel injection system may experience a fuel leak. CONSEQUENCE: A fuel leak in the injection system in the presence of an ignition source, increases the risk of a fire. REMEDY: Volkswagen will notify owners, and dealers will replace the fuel rails and corresponding seals, free of charge. The recall is expected to begin March 10, 2015. Owners may contact Audi customer service at 1-800-822-2834 or Volkswagen customer service at 1-800-893-5298. Volkswagen's numbers for this recall are 24AP for Audi customers and 24BK for Volkswagen customers. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov. ### RECALL Subject : Fuel Injection System may Leak Report Receipt Date: JAN 20, 2015 NHTSA Campaign Number: 15V016000 Component(s): ENGINE AND ENGINE COOLING Potential Number of Units Affected: 1,368 Manufacturer: Porsche Cars North America, Inc.
