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.

Fast sedans and loose Tweets | Autoblog Podcast #555

On this week's Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Reese Counts. Reese has been traveling a lot, and the two discuss his recent first drives of the 2019 Mercedes-AMG GT four-door and the 2019 Audi Q3. The pair also talk about the 2018 BMW X2 that's been in the office this week. Also on the agenda is the SEC's lawsuit against Elon Musk, Ola Kaellenius replacing Dieter Zetsche at Mercedes-Benz, Cadillac's move back to Detroit and the upcoming reveal of the 2019 BMW 3 Series at the Paris Motor Show.Autoblog Podcast #555 Get The Podcast iTunes – Subscribe to the Autoblog Podcast in iTunes RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown 2019 Mercedes-AMG GT four-door 2019 Audi Q3 2018 BMW X2 Elon Musk lawsuit New Mercedes-Benz CEO Cadillac is heading back to Detroit The new 3 Series debuts next week Feedback Email – Podcast@Autoblog.com Review the show on iTunes

A luxury crossover for people who like to drive | 2018 Audi Q5 First Drive

1.6 million. That's how many Q5s Audi has sold since the model's 2008 debut, making the agreeable but stylistically neutral sport-ute the best-selling premium SUV on the planet. One in four Audis sold is a Q5, which is a big part of why the German carmaker made significant improvements intended to ensure the 2018 Audi Q5 is another success story. For starters, the Q5 has swollen in size. Not by much – we're talking 1.3 inches in length, half an inch in wheelbase, and incrementally more height – but enough to boost rear legroom by 0.39 inch and add 0.31 inch to rear headroom. If you're worried that curb weight has bloated in direct proportion to the larger footprint, fear not: The 2018 model is actually up to 198 pounds lighter than the model it replaces, thanks to a carefully modulated blend of high tensile steels and aluminum in the chassis, and incremental weight savings throughout. Two turbocharged engines are available: the Q5's 2.0-liter TFSI engine producing 252 horsepower and 273 pound-feet of torque (doing the 0-to-62-mph sprint in 6.4 seconds), and the SQ5's 3.0-liter TFSI mill that turns 354 hp and 369 lb-ft (capable of whisking it to 62 mph in 5.2 seconds). The 2.0-liter meets a new seven-speed dual-clutch S tronic transmission, while the beefier 3.0-liter gets a conventional eight-speed torque-converter-equipped gearbox to handle the higher torque. Audi's new Quattro ultra setup (already seen in the A4 and Q7) offers fully variable torque distribution that helps achieve 20/27 mpg with the 2.0-liter and 18/26 mpg for the 3.0-liter. The system can de-couple the rear axle via an electronic clutch, which improves fuel economy; with 100 percent of torque directed to the front wheels during straight-line driving, the parasitic losses of running power needlessly through the rear differential are avoided, while a second clutch controls front/rear torque distribution. Audi says the ultra setup works proactively, not reactively, using torque vectoring to distribute power and anticipating changes in vehicle dynamics 500 milliseconds before the torque is redistributed. While there are numerous tech updates under the skin, the body itself is very familiar. In person, the Q5's looks are tweaked ever-so-slightly thanks primarily to a curvier, crisper character line that is so sharp, it casts its own shadow under certain lighting conditions. Inside, a Q7-like upgrade gives the cabin a more sophisticated feel.
