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 Q7 E-Tron confirmed?

Rumors out of Australia say we'll be seeing a new variant of the Audi Q7 when the next-generation models bows in a few years. Joining the diesel and gas range will be the second production member of Audi's E-Tron family, which was introduced by the R8 E-Tron, but will actually see production in the form of the A3 E-Tron.
Speaking with Audi's managing director in Australia, Andrew Doyle, Car Advice asked what the future held now that the electrified R8 had effectively been shelved. "I don't see it [R8 E-Tron] as a major thing for us. We'll launch [locally] with A3, followed by Q7..."
The new Q7 will share its platform with the Volkswagen Group's two other large SUVs, the Porsche Cayenne and Volkswagen Touareg. But, as Car Advice is quick to point out, the Porsche and VW variants are slated for arrive next year - the second-generation Q7 won't arrive until 2015. Doyle refused to explain the discrepancy.

2017 Audi S4 Avant is what forbidden fruit looks like

Take a good look at this lemon yellow Audi S4 Avant at the Geneva Motor Show, because you're not going to see one on the road in the US. That's really a shame, too, because for a family that wants to combine performance and utility, this seems like a great package. The S4 Avant takes the wonderful aspects from the latest S4 Sedan and adds just a little more to sweeten the deal. Drivers still get a turbocharged V6 and eight-speed transmission. Plus, Audi's famous all-wheel drive system and torque vectoring provide tons of traction whether motoring through a snow storm or taking a corner. In addition, customers get up to a massive 53.3 cubic feet of cargo space in the wagon, versus 17 cubic feet in the sedan. The only downside of the extra room is that the 0-62 sprint takes 4.9 seconds in the long roof versus the 4.7 seconds of the sedan. We'd take that trade-off. The Avant even looks better. Neither version is ugly, but the longer roof flows beautifully to the raked rear hatch. The result looks more elegant than the four-door. Unfortunately, these advantages simply add to the S4 Avant's status as very sweet forbidden fruit. American tastes might turn from crossovers to wagons someday, but until that unlikely prospect happens, enjoy these great shots of an enviable vehicle.

Its newly developed turbo V6 engine outputs 260 kW (354 hp). New solutions in networking and assistance systems round out its features. Audi is transferring many technologies from the full-size class into the mid-size class. Lightweight and strong: the 3.0 TFSI The strong heart of the two new S models from Audi is a newly conceptualized 3.0 TFSI engine. The direct gasoline injection engine with turbocharging has an output of 260 kW (354 hp) and produces a hefty torque of 500 Nm (368.8 lb-ft) from 1,370 to 4,500 rpm. In terms of power and torque, it surpasses the previous model while achieving considerably lower figures in weight and fuel consumption. The turbo V6 engine accelerates the Audi S4 from 0 to 100 km/h (62.1 mph) in 4.7 seconds, and on up to an electronically governed top speed of 250 km/h (155.3 mph). The standard sprint takes two tenths of a second longer in the S4 Avant.
