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 Traffic Light Assist helps you hit every green light

Before taking a ride in Audi's impressive Piloted Driving A7, we took a short spin up and down the Las Vegas strip to check out a smaller, but intriguing piece of Audi driver assistance technology called Traffic Light Assist that promises to help drivers make every green light.
Using both live and predictive data beamed into the vehicle's navigation unit via onboard wifi, TLA doesn't need a single camera to tell you when the light is going to change. Local data sources provide information about traffic light patters, and the in car system uses that data and the motion of the car to predict exactly how long it'll be until the green light goes red.
In practice, the system shows a traffic light icon in the central display (a head-up display would be a nice option), along with a countdown timer that reads the number of seconds before a light changes from red to green. Additionally, the system corrects (nearly instantly in our demo) for changing lanes and resultant changing signals; changing a straight-through traffic lane to a left-turn lane and signal, for instance.

VW Group plan puts Porsche in charge of a 'super-premium' division

An Automobile report looks into what's happening on the organizational and technical sides of the Volkswagen Group, and what those changes could mean for the premium brands. The wide-angle view is that Porsche appears to have been anointed to "coordinate the future activities" at Audi, Bentley, Bugatti and Lamborghini. Audi would cede Lamborghini guardianship to Stuttgart, and Ducati — via a new concern called Ducati Enterprises — would become the shepherd for VW's other Italian investments. Executives target Jan. 1, 2019, to complete the reshuffle. VW wants to save a boodle by tying up four of its five top-tier brands, and putting the one with the highest ROI in charge. Porsche, within its own house, wants to reduce expenditures by $2.3 billion per year over for four years, the savings already earmarked for improving internal processes like R&D and production. Having Porsche share those gains as well as lead development of platforms, components and future-tech strategies for the sister sports car brands could benefit everyone. In the near-term, the brands have their own plans: Bugatti CEO Stephan Winkelmann is said to want a Chiron Superleggera, a roofless and "completely reskinned" Chiron Aperta, and a track-only Chiron SS. The Superleggera could take the Chiron Sport's and Divo's Jenny Craig routines even further. The Aperta seems a natural successor to the Veyron Grand Sport, a natural evolution of the recently introduced Sky View roof, and a reskin might include numerous Divo cues. It's also said Bugatti's considering "an all-electric high-end model" in conjunction with Porsche, Rimac, and Dallara, but name one supercar or hypercar manufacturer that isn't considering a lightning-fast EV. Lamborghini, deep into work on follow-ups for the Huracan and Aventador, might get a bit of a bump with the new plan. The carbon "monofuselage" for the next V12 flagship is said to be too far developed and too complex to scrap. It puts two electric motors on the front axle, batteries in the middle, and a naturally aspirated V12 with around 770 horsepower plus another e-motor with 402 horsepower in back. The Huracan is said to get a version of the same carbon architecture at the moment, but the corporate reorganization might press pause on it. Automobile says options include continuing the Huracan/ Audi R8 twinning, but that depends on Audi saying "Ja" to a third-gen R8 with Lamborghini bones.
