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.

The Audi RS3 LMS looks hot and ready

Audi had several reveals this week at the Paris Motor Show, but nothing was more batty than the new RS3 LMS race car. Audi's latest hot homologation car starts with the all-new RS3 sedan, removes all of the unnecessary bits and adds all the racing-spec equipment you could want. The result is a full-prepped, relatively affordable factory race car. That relatively affordable part is very important. Audi Sport, the division behind the R8 LMS as well as the R and RS road cars, designed the RS3 LMS for the still-new TCR FIA-spec racing series. The cars will cost about $112,000 USD for the club sport version and $145,000 with the six-speed sequential transmission. Not bad for a fully FIA-friendly factory machine. The new TCR series races follow other FIA series like Formula 1 and WEC. <p>Your browser does not support iframes.</p> All that cash get's nets you a pretty badass looking car, especially in Audi's black and red paint scheme. As you can see in the photos, the RS3 LMS is far wider than the standard sedan, which is fairly compact by modern standards. The requisite giant rear wing is present, as is the big front splitter. The RS3 LMS ditches the new road car's dual exhaust for a cool looking single, center-exit pipe. Inside, it's all bare metal and plastic, ditching any semblance of road-going civility. Under the hood, the RS3 LMS loses the new 2.5-liter turbocharged inline-five and replaces it with Volkswagen's 2.0-liter turbocharged four. In this application, the engine pumps out a healthy 330 horsepower. Audi claims a 0 to 60 mph time of 4.5 seconds. Audi says customer deliveries will start in December, so look for the new car on track starting in 2017.

Audi calls R18 E-Tron Quattro its 'most complex race car'

Technically speaking, Audi's R18 E-Tron Quattro is quite technical. The German automaker says the diesel-hybrid is the "most complex race car" it's ever created. And we'll take their word for it. The Audi, which pairs a V6 turbodiesel powering the rear wheels with two electric motors, is all about connectivity, giving the car's crew the opportunity to constantly monitor the vehicle while it's racing. The car sends in a host of data each lap to the crew's computers, and the vehicle's telemetry system constantly keeps tabs on things like hybrid energy levels, cockpit temperature and boost-pressure levels. In all, the amount of data parameters is more than 100 times greater than in 1989, when Audi first tested a race car equipped with automatic data transmission capabilities. Audi first released specs on the updated version of the R18 E-Tron Quattro late last year, trumpeting the vehicle's advantages in competing in the LMP1 class of the 2014 World Endurance Championship (WEC). Audi made the car a little narrower and a little taller and it complies with a new WEC regulation requiring the front end set off by a new wing. Take a look at Audi's most recent press release below. AUDI R18 E-TRON QUATTRO WITH COMPLEX ELECTRONIC ARCHITECTURE • Telemetry connection between race car and pit lane • Permanent acquisition of far more than 1,000 parameters • Various electronic control units interlinked by a multitude of CAN Bus systems Ingolstadt, May 5, 2014 – The Audi R18 e-tron quattro is the most complex race car created in Ingolstadt and Neckarsulm to date. This not only applies to the mechanics. The electronics of the most recent LMP1 race car with the four rings is more sophisticated than ever before. The age of electronic data transmission from the race car on track began for Audi in 1989. At that time, an Audi 90 quattro in the IMSA GTO series radioed eight parameters to the garage where engine speeds and a few pressures and temperatures were plotted on printouts – a tiny step from today's perspective, but one that provided important insights at the time. Today, an Audi R18 e-tron quattro on more than a thousand channels, in cycles that in some cases only amount to milliseconds, generates data of crucial importance to a staff of engineers at Audi Sport. At Le Mans, the engineers constantly monitor their race cars for 24 hours.
