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.

Next-gen Audi RS4 coming, might make it to America

Let us be frank: The second-generation Audi RS4 was one of the best, most exciting cars of the past decade. A four-door sedan with a 4.2-liter V8, all-wheel drive, and a six-speed manual transmission? What wasn't to like? While you can still get a taste of the B7 RS4's character with the current RS5, it isn't quite the same. That's why we're giddy about a new report from Car and Driver, which claims that not only is a new RS4 on the way, but that it could, maybe, possibly return to the United States. As previously reported, the fourth-generation RS4 will go back to a twin-turbocharged V6, after two generations of unassisted V8s under the hood. As per RS4 tradition, it will also be limited to a five-door Avant body style, because "that is what people expect from the RS4," Quattro GmbH boss Heinz Hollerweger told Car and Driver. An RS5 Sportback could also be in the offing, which might remain more true to the character of the first US-market RS4. The US question, though, remains an iffy one, largely because of the Avant shape. Audi has reduced the number of wagons it's offered in the US over the years, dropping the A4 and A6 Avant, although the former is sort of still offered in the form of the Allroad. But that position might be enough to keep the next-gen RS4 off our shores, although as the Quattro boss told CD the US market is changing and "there is more demand there [for wagons], so maybe that will change." Well, Herr Hollerweger, we're here to tell you that America loves wagons, and that you should put the next-gen RS4 on sale over here post haste. Danke.

Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.
