The skinny on Delphi's autonomous road trip across the United States [w/videos]

Rolling out of an S-shaped curve along Interstate 95, just past Philadelphia International Airport, the final obstacle between the autonomous car and its place in history appeared on the horizon. So far, the ordinary-looking SUV had traversed the United States without incident. It had gone through tunnels and under overpasses. It circled roundabouts and stopped for traffic lights. Now, on the last day of a scheduled nine-day journey, it was poised to become the first autonomous car ever to complete a coast-to-coast road trip. First, it needed to contend with the Girard Point Bridge. Riding in a rear seat, "I saw that bridge coming, and I thought, 'Oh my gosh, this is going to be a grab-the-wheel moment," said Kathy Winter, vice president of software at Delphi Automotive. The car, an unassuming Audi SQ5 nicknamed Roadrunner, had been well-tested. Back in January, a few inebriated pedestrians fell flat in front of the car during a demonstration in Las Vegas. It was the quintessential worst-case scenario, and the car admirably hit the brakes. More than drunken louts, bridges present a sophisticated challenge for the six radar sensors that feed data to the car's internal processors. Instead of sensing solid objects, radar sensors can read the alternating bursts of steel beams and empty space as conflicting information. "They're a radar engineer's worst nightmare," said Jeff Owens, Delphi's chief technology officer. Girard Point Bridge, a blue skeleton of girded steel that spans the Schuylkill River, might be a bigger challenge than most. Traveling across the lower level of its double decks, the autonomous car's radar sensors had to discern between two full sets of trusses. Cross the Schuylkill, and Delphi's engineers felt confident they'd reach their destination: the New York Auto Show. For now, the sternest test of the trip lay directly in front of them. A Data-Mining Adventure Until that point, the toughest part of the journey had been finding an open gas station in El Paso, TX. Trust in the technology had already been established. The main reason Delphi set out on the cross-country venture with a team of six certified drivers and two support vehicles was to capture reams of data. What better way to do that than dusting off the classic American road trip and dragging it into the 21st century? They did exactly that, capturing three terabytes worth of data across 3,400 miles and 15 states.

Audi tops Consumer Reports' brand rankings while Tesla leads domestics at eighth

Tesla supplanted General Motors' Buick division as the top-ranked US automaker in Consumer Reports annual brand rankings, though the electric-vehicle maker finished eighth among global automakers. Buick had finished atop CR's domestic car-brand list for three years before Tesla leapfrogged it. Scores were calculated from a combination of performance, owner satisfaction, and reliability. CR noted that Buick scored big on reliability but not so high on performance, while Tesla appeared to present the opposite case. Volkswagen's Audi division repeated as the best overall brand for the second straight year, beating out VW's Porsche unit, BMW, Toyota's Lexus division, and Subaru. Kia and Mazda followed those brands, while Honda finished ninth, between Tesla and Buick. Consumer Reports took results from 31 brands. Reliability issues related to the Toyota Tacoma helped drop that Japanese automaker out of the top 10. Take a look at CR's results for its Annual Brand Report Card here. That Tesla, Audi, and Porsche placed so high is topical, given some of the issues plaguing those automakers. Audi, Porsche, and their parent VW have been coping with the effects of the diesel-emissions scandal that broke back in 2015. The scandal has cost Europe's largest automaker billions of dollars, and forced VW to put a stop-sale on diesel-powered cars in the US in late 2015. And while the Tesla Model S improved from the "worse-than-average" label CR gave it in its 2015 Annual Auto Reliability Survey, the problematic falcon-wing doors on the Tesla Model X SUV pulled that model's reliability scores lower last year. Additionally, the Model X's climate-control system and door locks have also caused issues. Toyota and Lexus finished atop CR's reliability rankings last year. Related Video:

Next-gen Audi A5 shows its heavily camouflaged face

The new Audi A4 is set to launch at the Frankfurt Motor Show in September, so it shouldn't come as too big of a surprise that an updated A5 is on the way, as well. Our spies just caught the coupe testing for the first time while wearing heavy camouflage from nose to tail. Despite the concealment, some details are possible to make out, especially when comparing the two-door design to the previously spied A4. Audi is further differentiating the designs, and the A5's front end is significantly changed based on these photos. The headlights appear larger and more acutely angled than the narrower units on the sedan. Also, the lower bumper gets square intakes at each corner and the shape creates an additional opening in the center for the coupe. In profile, it's easy to notice the quicker sloping roof and smaller side windows. Only the rear end of the two models seem to share many significant cues. The new A5 reportedly rides on the same MLB Evo platform as the upcoming A4 to shed around 200 pounds. The two models might not launch at the same time, though, and the coupe could join the lineup somewhat later. S5 and RS5 variants are expected to join the range further down the line, too.
