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 RS3 spy shots foreshadow an ultra-hot hatch

Not all vehicle prototypes and mules require heavy camouflage - sometimes they can be hidden in plain sight. That's probably what Audi was hoping for while testing its new RS3 wearing S3 duds, but thanks to some visual and audible telltales, our spy photographers were able to recognize this as a precursor to the marque's ultra-hot hatch testing near the Nürburgring.
Our photographer noticed the signature exhaust note of a five-cylinder engine, which suggests the RS3 could borrow its motivation from the excellent TT RS. Producing at least 340 horsepower, this 2.5-liter turbo powerplant could be the perfect answer for the new A45 AMG from Mercedes-Benz. The big brakes on this RS3 mule give us our best idea about the car's high-performance intentions, with Audi RS wave brake rotors and six-piston calipers peering out from behind the oversized wheels.
In production form, the RS3 should have a much different appearance from what you see here, with sportier design cues including oval-shaped dual exhaust outlets and a more aggressive front fascia. While we're still waiting for our first taste of the S3 in the North America, we'll be holding our breath for the RS3 to make its way here, as well.

2015 Audi A3 Sportback E-Tron

A little more than a year ago, I drove an Audi A3 E-Tron prototype - an early concept electric vehicle built on the outgoing second-generation A3 platform. While I was impressed with the technology, its 3,800-pound weight, 10-second 0-60 time and 90-mile range will likely put it only mid-pack, at best, among its future competitive set. But Audi promised bigger and better things would come.
I didn't have to wait long. Immediately following the Los Angeles Auto Show, Audi asked me come drive its all-new successor built on the company's third-generation A3 chassis. Compared to last year's model, the new plug-in hybrid electric vehicle (PHEV) boasts a lighter curb weight, quicker acceleration and six times the range. Calling it improved is an understatement. Best of all, it's heading to production.
Technically speaking, the 2015 Audi A3 Sportback E-Tron is a parallel hybrid, meaning its electric motor is sandwiched between a combustion engine and an automatic transmission - either, or both, is capable of powering the front wheels. The gasoline-powered engine is a direct-injected and turbocharged 1.4-liter four-cylinder, rated at 150 horsepower. The transmission is a six-speed dual-clutch gearbox. A 75-kW electric motor sits between the two. Water is used to cool the gasoline engine, the electric motor and the battery pack - there are three independent closed loops.
