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.

Mercedes may be working on a new electric car dubbed 'Ecoluxe'

Automobile has a lengthy piece this month on how the four German mass-market luxury manufacturers each plan to go after Tesla with their own electric vehicles. It was written by Georg Kacher, the magazine's European bureau chief, and the English version came a month after he wrote the German-language original for Autobild. Tesla isn't exactly a threat to the Germans, but, according to the report, the Model S is planting the right kinds of seeds in niches that are important to the luxury players. The thinking is that - in addition to needed electric vehicles anyway for stricter US regulations - it's better to start designing the machinery now. The article posited Porsche's attack would rest on the coming Panamera platform, but a big hurdle would be battery placement. Unable to find one large space for a lithium-ion pack, engineers would instead put batteries everywhere they could, for a supposed tally of some "108 battery pouches" throughout the body. A few days after the Automobile piece, however, Porsche publicly said it had no intention of challenging the Model S, because the enthusiastic driving the brand is known for doesn't jive with useful range. In Kacher's retelling, Mercedes' plans are even more ambitious, supposedly taking aim at the Model S and the coming Model X. It would do this with an investment in excess of $2 billion in a program called "Ecoluxe" – Mercedes has no brand division akin to BMW's i and Audi's e-tron. The new brand would create a four-strong family of bespoke electric vehicles: a smaller platform with a wheelbase around 106 inches and a larger one with a wheelbase around 118 inches. In addition, the range would have "provisions for rear-wheel drive, all-wheel drive, and rear-wheel steering." The numbers are impressive: seating for seven in the larger vehicles, both longer than 16 feet, front and rear storage areas, ratings of up to 610 horsepower and production capacity of 80,000 units per year. When would we see such creatures? Perhaps as soon as 2019. We do know that if Tesla can knock the Model X over the outfield fence, automakers are going to have to do something. We don't know what the chances are that Ecoluxe is Mercedes' first move - but such a plan could help explain the weird Mercedes concept spied in October.

Next Audi R8 to be up to 130 pounds lighter

"Simplify and add lightness," as Lotus founder Colin Chapman said. In a world where even supercars are subject to environmental, efficiency and emissions standards, lighter vehicles are being looked on as a sort of panacea - make it lighter, and it's automatically faster, more agile, easier to brake and better on gas.
Knowing this, it comes as no shock that Audi is looking at ways to lighten up its next-generation R8, with the brand's head of technical development Ulrich Hackenberg targeting a 110- to 130-pound diet for the mid-engine rocket. This supports previous reports regarding the focus for the next R8. Motor Trend reports that aluminum and carbon fiber feature heavily in plans for the next R8, which should go a long way toward slimming down even the lightest of R8s, the 3,678-pound V10 Plus model.
There's more over at Motor Trend, including the buff book's attempts to get Hackenberg to discuss powertrain options for the next R8.
