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 sets diesel records on road and track

Ever the proponent of diesel propulsion, Audi has claimed two very different kinds of records in Europe with its finest oil-burners. The more exciting of the two was achieved recently at the Sachsenring, where the Audi RS5 TDI Competition Concept posted the fastest diesel-powered lap time ever recorded on the track. As you may recall, Audi revealed the RS5 TDI Concept last year, swapping the gasoline-burning 4.2-liter V8 in the production RS5 coupe for a 3.0-liter V6 diesel with two turbochargers and an electric supercharger. The result was 385 horsepower and 553 pound-feet of torque, but Audi's been working on the prototype over the course of the past year. In the new Competition version, output is up to 435 hp and 590 lb-ft, and despite the inherently heavier diesel engine, it actually weighs 531 pounds less than the production model. That helped the RS5 TDI Competition lap the circuit in 1:35.35, besting the previous diesel lap record by 1.87 seconds, and adding to the Hockenheim record it took previously. Around the same time, another team set out from Maastricht in the Netherlands in an Audi A6 TDI Ultra and drove it for 28 hours straight, hitting 14 countries and logging 1,158.9 miles on a single tank of diesel. The achievement, certified by Guinness World Records, was completed in a showroom-stock vehicle, with automotive journalist Andrew Frankel and racing driver Rebecca Jackson splitting driving duties. They achieved an average of 75.9 miles per gallon – much better than the advertised rating of 67 mpg – as they cruised through from Holland to Hungary, passing along the way through Belgium, Luxembourg, France, Switzerland, Lichtenstein, Austria, Germany, Italy, Slovenia, Croatia, Bosnia, and Serbia. Record: Audi RS 5 TDI competition concept drives to record time on the Sachsenring track - Audi sets new lap record for cars with diesel engines - Superior technology platform with 435 hp and 800 Nm (590.0 lb-ft) - Electric compressor: overcomes turbo lag, enhances sprint performance Audi has set a new record time on the Sachsenring for cars with a diesel engine. The Audi RS 5 TDI competition concept rounded the 3.6 km (2.2 mi) race course in a time of 1 minute 35.35 seconds. The technology platform draws its power from a 3.0-liter V6 biturbo TDI with 320 kW (435 hp) of power and 800 Nm (590.0 lb-ft) of torque. The highlight is an electrically driven compressor.

Ferdinand Piech (1937-2019): The man who made VW global

Towering among his peers, a giant of the auto industry died Sunday night in Rosenheim/Upper Bavaria, Germany. Ferdinand Piech, a grandson of Ferdinand Porsche, who conceived the original Volkswagen in the 1930s, was the most polarizing automotive executive of our times. And one who brought automotive technology further than anyone else. Ferdinand Porsche had a son, Ferdinand (called "Ferry"), and a daughter, Louise, who married the Viennese lawyer Anton Piech. They gave birth to Ferdinand Piech, and his proximity to two Alfa Romeo sports cars — Porsche had done some work for the Italians — and the "Berlin-Rome-Berlin" race car, developed by Porsche himself, gave birth to Piech's interest in cars. After his teachers in Salzburg told his mother he was "too stupid" to attend school there, Piech, who was open about his dyslexia, was sent to a boarding school in Switzerland. He subsequently moved on to Porsche, where he fixed issues with the 904 race car and did major work on the 911. But his greatest project was the Le Mans-winning 917 race car, developed at breathtaking financial cost. It annihilated the competition, but the family had had enough: Amid growing tension among the four cousins working at Porsche and Piech's uncle Ferry, the family decided to pull every family member, except for Ferry, out of their management positions. Piech started his own consultancy business, where he designed the famous five-cylinder diesel for Mercedes-Benz, but quickly moved on to Audi, first as an engineer and then as CEO, where he set out to transform the dull brand into a technology leader. Piech killed the Wankel engine and hammered out a number of ambitious and sophisticated technologies. Among them: The five-cylinder gasoline engine; Quattro all-wheel drive and Audi's fantastic rally successes; and turbocharging, developed with Fritz Indra, whom Piech recruited from Alpina. The Audi 100/200/5000 became the world's fastest production sedan, thanks to their superior aerodynamics. Piech also launched zinc-coated bodies for longevity — and gave diesel technology a decisive boost with the advent of the fast and ultra-efficient TDI engines. Less known: Piech also decided to put larger gas tanks into cars. Customers loved it. Piech's first-generation Audi V8 was met with derision by competitors; it was too obviously based on the 200/5000.
