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 Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

Audi shows off the Prologue Avant Concept as a plug-in hybrid

The Audi Prologue Avant Concept goes in a different direction than the Prologue coupe, in more ways than just its five-door wagon body. The coupe was first shown at the LA Auto Show with a 4.0-liter, twin-turbo V8, then went redux at CES as a hybrid with a total of 677 horsepower and 701 pound-feet of torque. The only-slightly-larger Prologue Avant sticks with the hybrid but gets the system from the Q7 E-Tron quattro, meaning a 3.0-liter, twin-turbo V6 TDI with 353 hp and a 100-kW electric motor strapped to the eight-speed transmission. Total output is 455 hp and 553 lb-ft, pure electric range is 33 miles, and 0-62 miles per hour comes in 5.1 seconds. The forward section of cabin with its screen-based Tie Fighter displays and controls comes over from the coupe, as well as the four individual seats, but the Avant lavishes attention on rear passengers in ways not possible in the two-door. They also get a screen on the pass-through center console for convenience controls, and detachable OLED screens - a la the detachable tablets in the Q7 - with which they can send information to the front occupants. As a traditional Audi avant is to a coupe relative, the Prologue Avant is all about bringing the family along on the digital highway. We'll see it at the Geneva Motor Show next week, and Audi is again talking up how the design language will migrate to production cars. It also makes noises in the press release below about near-production many of the technologies are in the concept, so it looks like there could be all sorts of Easter Eggs on the way from the Ingolstadt brand.
