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.

VW confirms development of 10-speed dual clutch, 134-hp/liter diesel

Each year, the Vienna International Motor Symposium showcases some of the up-and-coming technologies automakers are engineering for the use in passenger cars, and Volkswagen AG CEO Martin Winterkorn revealed some big developments VW is working on for its future products. Winterkorn discussed a multi-faceted approach that VW is looking to reduce its fleet fuel consumption and exhaust emissions.
Some of the bigger news he discussed included a "high-performance" diesel engine that will produce 134 horsepower per liter and a 10-speed DSG automatic transmission. While no specific applications were mentioned, we can only hope this is for the Audi R4 we keep hearing about.
Another topic he touched on that caused us to perk up our ears was had to do with VW's plug-in hybrid technology. While we know the PHEV versions of the Audi A3 and Porsche Panamera are on the way, Winterkorn also said that these two models will be followed up by Golf, Passat, Audi A6 and Porsche Cayenne plug-in models. Scroll down for a press release highlighting the automaker's future fuel-saving initiatives.

Audi R8 LMX has frickin' lasers for headlights

It might look like just another Audi R8, but Ingolstadt tells us this one is different: it is the limited edition Audi R8 LMX (click image above to enlarge) with laser-enhanced LED high-beam headlights. Audi introduced the laserlight technology on its R18 E-tron Quattro LMP1 race car and then promised a production version of it at this year's Consumer Electronics Show. The eyes on the R8 LMX employ the same method when traveling above 37.3 miles per hour, utilizing a tiny laser module in each headlight that, after conversion to white light, can throw a beam about 1,640 feet down the road.
Because no one should ever stop at lasers, buyers of the limited-to-99 examples of the R8 LMX will also get a more powerful engine, with 570 horsepower erupting from the mid-mounted V10; that's ten more horses than came with the R8 V10 GT introduced last year, but the 0-62 mile-per-hour time hasn't budged from 3.4 seconds. It comes in coupe form only, dressed in Ara Blue paint with carbon accents all around, exclusive wheels, red brake calipers, and a black Nappa leather interior with contrasting blue bits.
The order book is open now, and deliveries will begin this summer for those willing to lay down 210,000 euros for the privilege of using one of Superman's powers for good, as standard (the BMW i8 has laser-equipped high beams, but as an option). We won't see them here, though, for as with Matrix Beam lighting and Audi's sequential turn signals, US laws forbid such shenanigans. The press release below has more info.
