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.

Audi pins hopes on 2016 R18 Le Mans prototype

Down but not out, Audi is carrying forward its endurance racing program with the new R18 you see here. Unveiled on Saturday at the Audi Sport Finale end-of-season event in Munich, the new LMP1 is billed as the company's its most powerful and efficient race car yet. And it has been thoroughly redesigned to bring the Four Ring brand back to the winner's circle. Though technical details remain a closely guarded secret, Audi says that the latest evolution of the R18 (now apparently labeled sans the E-Tron Quattro) benefits from revised aero, lightweight construction, and "a modified hybrid system with lithium-ion batteries for energy storage, plus an efficiency-optimized TDI engine." That spells the end of the mechanical fly-wheel setup of the previous version, but sticks to the diesel fuel that Audi has championed instead of the gasoline favored by rivals Porsche and Toyota. With all its revisions, Ingolstadt undoubtedly hopes this latest version will perform better than the last. This past season was the worst Audi has endured since 2009. Its sister company Porsche beat it to both the drivers' and manufacturers' titles in the FIA World Endurance Championship and to the winner's circle at the 24 Hours of Le Mans. That marked the second straight year of defeat in the championship, following Toyota's domination last season, and marked only the third time Audi was defeated at Le Mans since 2000, following Bentley's win in '03 and Peugeot's in '09. In order to avoid costly inter-agency arms race, Audi and Porsche have agreed to each field two entries instead of three in both the championship and the headline race in Western France. Audi has yet to confirm its driver lineup, but Porsche has revealed its lineup consisting of defending champions Timo Bernhard, Brendon Hartley, and Mark Webber in one car, and Romain Dumas, Neel Jani, and Marc Lieb in the other. That leaves out the Le Mans-winning trio of Nico Hulkenberg, Nick Tandy, and Earl Bamber, with the former already counted out due to an F1 conflict. More powerful and efficient than ever before: Audi R18 celebrates world premiere in Munich - New hybrid race car for the 2016 Le Mans 24 Hours - Unchanged driver line-up in the DTM - High demand for new Audi R8 LMS GT3 sports car The brand with the four rings will be entering the 2016 motorsport season with the most powerful and efficient race car Audi has ever built.

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.
