2014 Audi A6, A7 and Q5 TDI diesel models get pricing and fuel economy figures [w/videos]

Last year, Audi announced that it was expanding its lineup of TDI models for 2014 with the Q5, A6 and A7 joining the diesel-burning Q7 and A8 L models already in existence. The Q7 TDI has been out for a few years now and we recently drove the A8 L TDI, but now Audi has released the pricing, performance and fuel economy details for the 2014 Q5 TDI, A6 TDI and the ever-stylish A7 TDI. Down the road, Audi has also promised a TDI version of the next-generation A3 that will debut for 2014.
Until the new A3 TDI shows up, the Q5 will be the most affordable diesel model in Audi's lineup, with a starting price of $46,500 to go with fuel economy estimates of 24 mpg city and 31 mpg highway. The closely related A6 and A7 will get identical fuel economy numbers of 24 city and 38 highway in diesel form, with the A6 TDI starting at $57,500 and the A7 TDI starting at $66,900. In the three new TDI applications, Audi's 3.0-liter V6 produces 240 horsepower and 428 pound-feet of torque, and all models are paired with an eight-speed automatic transmission. Scroll down for videos (stock running footage) and more information on the Q5 TDI, A6 TDI and A7 TDI, all of which go on sale in late summer.

Delphi thrilled with results from autonomous car's cross-country trip

In the first trip across the United States ever made by an autonomous car, engineers from Delphi Automotive were surprised to learn that, in some cases, their vehicle behaved a lot like a human driver. "The car was scared of tractor trailers," said Jeff Owens, the company's chief technology officer. "The car edged to the left just a little bit when it would pass trucks, and that was an interesting observation." Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions. In the course of the cross-country drive, drivers actually controlled the car only for about 50 miles, and those cases were limited to on-and-off ramps and the occasional construction zone where lanes were not marked or only sporadically marked. The purpose of the trip was to glean information on how the autonomous car worked in a real-world environment. Google and others have tested autonomous cars and autonomous features in select real-world environments before, but Delphi's adventure was the first to trek into a test with such varied challenges over a nine-day trip that began near the Golden Gate Bridge on March 22. There are some things the engineers have already learned, like the fact the camera systems had the occasional blip when the sun-angle was low. And there are some things to still be learned, as they pour over three terrabytes worth of data from cameras, radar and lidar sensors in the weeks ahead. "It's going to take us a couple weeks to digest all this," Owens said. "But we had all the data from tests. It was time to put this on the road." Built into an Audi SQ5, the vehicle was striking, if only for the fact it looked like a normal car. Many other autonomous vehicles have quirky sensors atop the roof or other features that make them stand out as experiments. Delphi arranged this one to look as much like a normal car as possible, right down to stowing an army of computers under cargo mats, so the rear contained as much trunk space as the production model. If a fellow motorist didn't know where to look -- or take the time to notice the person in the driver's seat didn't have their hands on the wheel -- there was no reason to suspect this was anything other than a regular car.

AMS Alpha 10 Audi R8 First Drive [w/video]

Horsepower is a relative number. Compared to the 1,500 hp in the last AMS car we drove, the face-melting Alpha 12 GT-R, 900 seems pretty tame. But by any rational standard that's a crazy amount of power, the kind that's hard to grasp in practical terms. When AMS Performance called us and offered a test in the 921-hp Alpha 10 Audi R8, saying yes was easy. Figuring out how to demonstrate that much thrust was the tricky part. Our solution was to head to the drag strip. What better way to show off the wicked alterations wrought by AMS president Martin Musial and his team than a video showing the car do the Star Trek warp speed effect through the quarter mile? AMS has a history of building quick drag strip cars, like the aforementioned GT-R and a series of Mitsubishi Lancer Evolutions. Vice president Arne Toman even owns the world's fastest Hearse. We should have taken the broken scoreboard at Milan Dragway as an omen. Wiped out by a lightning strike, both displays have since been replaced. Before our test both Musial and Toman explained that the Alpha 10 R8 wasn't built with drag racing in mind. But, being good sports, both met us at the track in southeast Michigan, unloaded the R8 from its trailer, and let us run through the timing lights over and over. The best time that day was 11.0 seconds at 136 mph, uncorrected. One of the many amazing things about the Alpha 10 Audi R8 is that it's essentially a bolt-on system. That's fast, but not what you'd expect for 786 horsepower at the wheels. And, honestly, we're not disappointed. First, a 4,200-rpm rev limiter was set too low to launch on the sticky drag strip. Put another way, that drag strip time is almost a street start. For what it's worth, Musial and Toman didn't seem concerned about the numbers. Like we said, they present the Alpha 10 as an all-around performance car, and we believe them. Now, if you go to AMS with the drag strip in mind, Musial and his staff can program whatever launch rpm you desire. (You're on your own for clutch replacements.) A reflash of the engine controller is part of the Alpha 10 package. Drop off a stock R8 V10 at AMS (or any of its 70-plus dealers), and they'll pull out the suitcase-shaped muffler that sits behind the engine. A pair of turbochargers, small mufflers, and two heat exchangers attach to the stock exhaust system mounts, while a giant water-to-air intercooler sits on top of the engine.
