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:

2017 Audi S4 First Drive

For all its power and easy performance, the best thing about the last Audi S4 was its uncanny ability to act like a normal (but very high-spec) A4 for most of its life. Then, when you needed or wanted a bit more speed or a bit more grip, you pushed a button or opened the tap and it became something else. It became a thing with more grip, more poise, more focus, and more gristle, but the changeover between the two S4 characters was seamless. That doesn't seem to be the case with the new one. The latest, B9 A4 has been well received and is probably the best mid-sized premium car out there, so that should have left the S4 a simple job to become the best warmed-up premium mid-sizer. It hasn't quite happened like that. The spec sheet suggests the S4 should come out on top in the fight with the BMW 340i and the Mercedes-AMG C43, but the numbers aren't everything. The engine seems impressive on paper; the all-new EA838 3.0-liter turbocharged V6 was jointly developed with Porsche (and it's closely related to Porsche's next V8, with which it will share non-internal bits like the camshaft chain). The 60-degree V6 weighs 31 pounds less than the old S4's supercharged V6, and it's replete with variable valve timing and lift, centrally mounted fuel injectors, and both direct and indirect fuel injection. That gives it 354 horsepower at 5400-6400 rpm (up 6.5 percent) and 369 pound-feet of torque from 1,370 to 4,500 rpm. That gives it a peak 44 lb-ft higher than the old one, spread across a band 600 revs broader. At 2,000 rpm, where drivers live every traffic light, it has another 74 pound-feet. That's enough motivation to move to 62 mph in 4.7 seconds. There's a new all-wheel-drive system that usually shoots 60 percent of the torque to the back but can ramp that up to 85 percent when it needs to, or it can swing it around to fire more than 70 percent to the front axle. The category benchmarks suggest turbocharged 3.0-liter gasoline sixes are the thing to have, with the Mercedes-AMG C43 using one, the 340i BMW having one (though it's straight), and Maserati's Ghibli also using one. The oddball is Jaguar's XE S, which uses a supercharger. You know, like Audi just ditched. The S4 trumps all but the C43 on power (the nine-speed Benz has 362 hp). While it ties the Ghibli for torque, it again trails the Benz (by 15 lb-ft) though its torque peak hits far earlier (the Benz waits until 2,000 rpm).

Toyota, Lexus dominate KBB's Best Resale Value Awards

Toyota and Lexus stormed the 2014 Kelley Blue Book Best Resale Value Awards, winning a combined 18 categories including best brand and best luxury brand. This marks the third year in a row that both automakers have won the Brand and Luxury Brand resale value awards. In all, Toyota won 11 categories and Lexus won seven.
Honda made a good showing, as well, winning two segments (Accord Plug-In Hybrid and Civic Si) and putting one car on the top-10 Best Resale Value list (CR-V). Chevrolet did even better, winning two segments (with the V6 Camaro and the Corvette) and placing three cars on the top-10-overall list (again, the Camaro and Corvette, plus the Silverado 1500).
The other winners came from Jeep, Dodge, Infiniti, Subaru and Audi. To give you a clearer picture of the Toyota and Lexus domination, their 18 mentions represents more than half of the 34 awards (including the top-10-overall list).
