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.

Watch VW Group Night kick off the Frankfurt festivities

The Frankfurt Motor Show is Volkswagen's home affair. As a result, the whole of the automaker group makes a big splash, even before the show doors open. We'll be live from the Frankfurt floor starting early tomorrow morning, but tonight we're posted up in the stands at the always-entertaining Volkswagen Group Night. To give you a taste of what it's like to be there, we're going to be shooting some man-on-the-scenes video as the night progresses. Below you'll find videos of all the best that VW Group brands – Audi, Lamborghini, VW, the lot – have to offer, as quick as we can upload them. So, enjoy the Short Cut Videos you see here. And stay tuned as we add more to the tally, below. And, of course, be sure to check in on Autoblog early and often tomorrow, when we bring you official debuts of new production vehicles and concept cars, a ton of new video content, live image galleries, and lots more.Seat Leon Cross Sport Bentley Bentayga Lamborghini Huracan LP 610-4 Spyder Volkswagen Multivan PanAmerican Edition Bugatti Vision Gran Turismo Concept Audi E-Tron Quattro Concept Audi A4 Ducati Monster 1200 R Volkswagen Tiguan Skoda Superb Combi Porsche 911 Carrera S Coupe and Cabrio Volkswagen Tiguan GTE Porsche Mission E Concept Volkswagen Group Night Finale Green Frankfurt Motor Show Audi Bentley Bugatti Lamborghini Volkswagen SEAT Skoda Videos Original Video Frankfurt 2015

2018 Audi RS3 Sedan to make US debut in 2017 [UPDATE]

UPDATE: We've heard back from Audi, and the statement was as expected. According to spokesman Mark Dahncke, there's "nothing we can share at this time." We really want the Audi RS3 to come to the US market, and based on a report from Car and Driver, it doesn't sound like we'll be stuck waiting that long. The report claims the new compact rocket sedan will debut next year as a model year 2018 vehicle. Beyond that date, C/D's report expands on some of the details we reported on in our RS3 Sedan report from February. It backs up the claim about a 2.5-liter, turbocharged five-cylinder, but instead of a 400-plus-horsepower engine, C/D's report says it'd be "close to" 400 hp. That power would come from a turbocharged, 2.5-liter five-banger that's distinct from the unit currently offered in the Euro-market RS3 Sportback and the last-generation TT RS (the new 2.5 would first debut in that car's replacement). The new powerplant would be paired with Audi's seven-speed S-Tronic. According to C/D, all this powertrain goodness will allow the new RS3 to hit 60 in four seconds flat and run up to 174 miles per hour. If correct, that means Audi's newest high performer will be a tenth of a second faster to 60 and have an extra seven mph on the high end than the most potent Mercedes-Benz CLA45 AMG. And while the two-door BMW M2 isn't necessarily a direct competitor – because coupe – it's worth pointing out that the RS3 will be 0.2 seconds faster to 60 and have an extra 19 mph to its top speed. While C/D's report cites a "highly reliable source" for its information, we've naturally reached out to Audi to confirm as much as possible. We'll update this post as soon as Audi's PR team gets back to us. The company basically gave the usual "No comment." Related Video: News Source: Car and Driver Rumormill Audi Luxury Performance Sedan
