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:

VW won't let emissions scandal keep it from racing

The Volkswagen Group may have its hands full dealing with the diesel emissions scandal. But that doesn't mean it will be curbing its considerable racing programs. At least not in any significant way. This according to Matthias Muller, who recently moved up from his previous position as Porsche CEO to preside over the entire group. Speaking with Autosport at the World Endurance Championship finale in Bahrain this past weekend, Muller emphasized the importance of racing to the company. "The motorsports programs are not in danger of being dropped or significantly reduced because motorsports is very important for the group and the brands," said Muller. "Basically we do not question our motorsport efforts." Of all the brands under the group's umbrella, several have prominent, top-level factory works racing programs, and others support customer racing teams. The Volkswagen brand has emerged as the dominant force in the World Rally Championship, securing both titles over the past three years. Both Porsche and Audi compete in the top tier at Le Mans and in the World Endurance Championship, trading places in the winner's circle. Audi also competes in DTM, and alongside Lamborghini, Bentley, and Porsche, and also offers GT3 and GTE racing cars to private customers. Lamborghini, Porsche, Audi, and Seat (once the leader in touring cars) all run their own spec racing series as well. Skoda continues to compete in lower-level rallying, leaving only Bugatti to draw on its prominent pre-war grand prix racing history. To hear Muller tell it, those racing programs – or at least the top-levels ones among them – aren't going away anytime soon. But there may still be some tweaks here and there, and we shouldn't expect any new programs to be launched in the near future. Porsche, for example, is anticipated to wind down its factory involvement in GT racing, after winning both the drivers' and manufacturers' titles in the WEC GTE Pro class this year in addition to its LMP1 victories. Instead it will focus on preparing new racing versions of the 911 for client racing teams. The auto giant was also reportedly close to branching out into Formula One in partnership with Red Bull. But after negotiations were interrupted by emergence of the diesel emissions scandal, that deal fell apart. It remains unknown which brand might have been represented in the F1 engine-supply program.

BMW reclaims US luxury sales crown from Mercedes

The numbers, they are in: BMW has reclaimed the luxury-sales crown from Mercedes by a margin of 9,347 cars. Mercedes donned the king's headgear in 2013 after a strong final quarter of 2013 when the new CLA and S-Class poured out of dealerships. This year, led by the 3 Series/4 Series and X5, BMW sold 339,738 units – a 9.8-percent increase year-on-year. Mercedes, led by the C-Class and M-Class, saw its sales go up by 5.7 percent to 330,391 units. We'll have to wait a bit to see if there's another registrations-vs-sales challenge as in 2012, when BMW was anointed US luxury ruler. Behind them, a dark horse named Lexus nudged closer to the leading Teutons, selling 311,389 cars. The Japanese luxury automaker also had the biggest gain among the top three, its sales rising by 13.7 percent compared to 2013. Audi had the biggest sales of anyone among the top five, though, with a 15.2-percent gain to 182,011, which moved it a spot ahead of Cadillac; the Wreath-and-Crest brand dropped 6.5 percent to 170,750. Acura (167,843), Infiniti (117,300), and Lincoln (94,474) took the final positions. Speaking of Lincoln, sales at the once-mighty luxury marque stand as the mightiest jump of any on this list, up 15.6 percent. That's the power of Matthew McConaughey... and better cars and a new crossover, sure. So now that we're back to Round One of 2015, in case no one else has said it yet: "Ok, fight!"
