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 planning A7 powered by fuel cell?

Back in March, Volkswagen AG CEO Martin Winterkorn voiced his doubts about the cost and infrastructure associated with building hydrogen fuel cell vehicles, but according to Autocar, that isn't stopping Audi from developing a fuel-cell version of the Audi A7. While we're inclined to take this report with a grain of salt, this wouldn't be the first time a VW executive has made seemingly damning statements about electric powertrains that later proved to be incorrect.
After speaking with Audi technical chief Wolfgang Dürheimer, Autocar reports that Audi is building a fuel cell A7 that is expected to be ready for testing by August. Like the electric E-Tron and natural-gas-powered G-Tron models, the hydrogen fuel cell Audis could, if produced, carry their own "tron" nomenclature.

Electric 1960 Auto Union 1000S has vintage looks, modern power

If you want to buy a classic car but somehow feel a twinge of guilt about the old engine polluting too much, then it's worth taking a look at this 1960 Auto Union 1000S on eBay Motors. The owner removed the original three-cylinder, two-stroke and installed a fully electric powertrain. In place of the internal combustion engine, there's an Azure Dynamics three-phase AC24 motor to spin the front wheels, and it even has regenerative braking. Lithium-ion batteries replace the rear seat and extend into the trunk to supply 21.5 kWh of energy storage. The seller claims the Auto Union weighs 2,400 pounds, so the powertrain might be rather lively in such a light car. From the outside, this Auto Union is immaculate. The owner's body-off restoration includes powder coating the chassis and suspension and repainting the exterior in Ascot Grey with the white roof. The color scheme looks perfect on cars of this era. The interior now has a digital instrument cluster in the center of the dash. We could see this change upsetting some purists because of the clash between original and modern. However, the reupholstered fabric seats look amazing. The owner has covered 15,000 miles since the restoration, so any powertrain bugs have been worked out in that time. As of this writing, the bidding is at $15,100 with 28 bids and the reserve is not yet met. The auction ends Sunday, April 10. While the seller provides great photos with the sale, you can see the EV in motion below in a video Audi created about it in 2014.
