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 races ahead with new R8 LMS [w/video]

The biggest news from Audi at the Geneva Motor Show may very well be the reveal of the all-new, second-generation R8 supercar. But the road-going version isn't the only one it's rolling out at the Swiss expo, where it's joined by the new competition-spec R8 LMS. Set to hit race tracks around the world next season, the new Audi R8 LMS picks up where the current one leaves off, having taken 26 GT3 Championship victories and seven 24-hour race wins between 2009 and 2014. That's a heck of a mantle to assume, but the new model looks like it'll be up to the task. Based on the new road-going R8, the new LMS is built to 2016 GT3 regulations and in many ways even exceeds them. In fact, Audi says it meets the more stringent crash requirements for the LMP1 class, and includes its state-of-the-art Audi Protection Seat PS 1 from the R18 E-Tron Quattro. It also incorporates the emergency hatch Audi built in to its DTM racers. Of course, there's more to the new R8 LMS than safety. Despite the addition of those features, the whole package is a good 55 pounds lighter than the outgoing model, thanks to the lightweight spaceframe chassis and the increased use of carbon-fiber components – all the while offering more torsional rigidity. Power still comes from Audi's celebrated 5.2-liter V10 engine producing 585 horsepower, but is now mated to a new six-speed sequential gearbox and benefits from an entirely new electrical system, improved airflow and optimized aerodynamics. All that and more ought to help the new R8 LMS and its customer racing teams achieve the success they're after once it makes its competitive debut at the Nurburgring 24-hour race in mid-May 2016.

As one of the first automobile manufacturers to do so at the beginning of the 2015 season, the brand with the four rings is presenting a race car that already meets the requirements of the new GT3 regulations to be introduced in 2016. The new Audi R8 LMS is lighter and safer than ever before. It features even more race car technology, clearly improved aerodynamics and, as a result, provides customers with an efficient concept. Back in spring of 2014, Audi began testing the new R8 LMS that is following in big footsteps.

Audi reveals even more efficient 2015 R18 E-Tron Quattro

We've seen two of this year's LMP1 manufacturer challengers – Porsche's updated 919 Hybrid and Nissan's GT-R LM Nismo. Audi has finished cooking up the successor to its Le Mans champion and unveiled the fifth-generation R18 E-Tron Quattro, even better than before. The bodywork monocoque is carried over, but the body around it has been reshaped to improve airflow from front to rear with a new hood, front fenders and wheel arches, and radiator configuration. The engine cover behind the cockpit is shrunk more closely around the engine, and there are new headlights. The hybrid system can expend double the energy per lap this year, putting Audi in the four-megajoule class under the energy-use regulations. That extra energy will come from 17-percent more capacity built into the flywheel storage system and an electric motor good for 272 horsepower. The revisions haven't increased the weight of the car, pegged to the minimum allowed at 870 kilograms. They have, however, forced changes to the TDI engine, which has to use 2.5-percent less fuel per lap to offset the increased hybrid output. The 558-hp V6 has been optimized such that it "managed to more than compensate for the loss" of fuel allowed, and Audi expects "significantly" lower lap times this year and less fuel used. We're still waiting to see what Toyota has done to its World Endurance Championship-winning racer, but we're already looking forward to this year's Le Mans. It's going to be cracking. You'll find a press release below the videos with more info on the Audi.

In the FIA World Endurance Championship (WEC) and in the Le Mans 24 Hours as the season's pinnacle event, Audi is going to compete with a hybrid sports car in the 4-megajoule class. A twofold quantity of hybrid energy, fundamentally revised aerodynamics, the next step in lightweight design and a lot of detailed work characterize the fifth generation of the Audi R18. "The possibilities of the revolutionary regulations that have been in effect for LMP sports cars since 2014 are far from having been fully used.
