Stanford goes from Pikes Peak to Thunderhill with autonomous Audi TTS

In the years since Stanford University engineers successfully programmed an Audi TTS to autonomously ascend Pikes Peak, the technology behind driverless cars has progressed leaps and bounds. Back then the Audi needed 27 minutes to make it up the 12.42-mile course – about 10 minutes slower than a human driver. These days, further improvements allow the vehicle to lap a track faster than a human. The researchers recently took their autonomous TTS named Shelley to the undulating Thunderhill Raceway Park, and let it go on track without anyone inside. The Audi reportedly hit over 120 miles per hour, and according to The Telegraph, the circuit's CEO, who's also an amateur racing driver, took some laps as well and was 0.4 seconds slower than the computer. To make these massive technological advancements, the Stanford engineers have been studying how racers handle a car. They also hooked up drivers' brains to electrodes and found the mind wasn't doing as much cognitively as expected. It instead operated largely on muscle memory. "So by looking at race car drivers we are actually looking at the same mathematical problem that we use for safety on the highways. We've got the point of being fairly comparable to an expert driver in terms of our ability to drive around the track," Professor Chris Gerdes, director of Stanford's Revs Program, said to The Telegraph. With progress coming so rapidly, it seems possible for autonomous racecars to best even elite drivers at some point in the near future. Related Video:

Audi re-illuminates Sport Quattro with Laserlight concept for CES

Automakers typically spend months working on a concept car, then unveil it at a car show and move on to the next. But Audi has demonstrated a propensity at refining the same concepts and bringing them back for more. Just look at how many time Audi iterated its E-Tron concept, and how many diesel R8s it toyed with. It brought the Italdesign Parcour out of retirement and rechristened it the Audi Nanuk, and it's been doing the same with the Quattro concept for the past several years. The German automaker rolled out the first Quattro concept back in 2010, and followed up with the reborn Sport Quattro concept less than a year ago. And now it's preparing to unveil yet another.
Called the Sport Quattro Laserlight concept, this time it's not as radical a departure from the Sport Quattro concept as that was from the first Quattro concept. In fact, there's really only one vital difference. That'd be the laser headlights "that leave all previous systems in the dark," according to the press release below. The system uses matrix LEDs around the outside of the element as low beams, and lasers on the inside for high beams. Measured in mere microns, the laser diodes are significantly smaller than LEDs, while lighting up the road ahead for nearly half a kilometers (1,640 feet), providing twice the lighting range and three times the brightness of LED high beams.
Otherwise the concept car you see here and which Audi will display at the Consumer Electronics Show in Las Vegas next week is essentially the same as the one it showed in Frankfurt this past September. It's got the same measurements, wearing the same CFRP bodywork, with the same interior and the same 700-horsepower hybrid powertrain, only the yellow exterior has been repainted Plasma Red and the black interior redone in a more low-key Slate Grey, as you can see from the high-res image gallery above.

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.
