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.

Porsche offering 250-hp 718 Cayman, Boxster in China

Porsche is studying a new approach in the lucrative Chinese market – less power. Automotive News Europe reports that the famed German manufacturer will sell less powerful versions of the 718 Cayman and Boxster in the People's Republic. In fact, the new cars are already on Porsche's Chinese consumer page. The hope, 718 chief Jan Roth told Automotive News Europe, is to replicate the success Porsche's sister company Audi has had with the TT. "A lot of the TTs that Audi sells in China, the smaller displacement 1.8-liter versions with rear-wheel instead of all-wheel-drive, are priced below that, Mercedes too," Roth said. We're guessing the comments about rear-wheel drive and a 1.8-liter engine are either typos or something was lost in translation, because Audi's Chinese website only lists a 2.0-liter engine, and most gearheads know the TT rides on a front-drive platform. Audi's success is largely down to price – 542,800 yuan ($81,549, at today's rates) for a base TT. Roth called 600,000 yuan "a magical threshold for customers in China." To hit that price point, Porsche is dropping the 718's 2.0-liter, turbocharged four-cylinder – offered North America and Europe with 300 horsepower in base form – to 250 ponies. The Cayman starts at 588,000 yuan ($88,340) while the Boxster is 598,000 yuan ($89,842). The 350-hp Cayman S will carry on unchanged. According to ANE, Roth said Porsche's Chinese strategy could drive 718 sales up to 4,500 units a year by 2017, nearly double the 2,500 Boxsters and Caymans sold in 2015. Could a similar lower-tiered strategy work in the US? We'll need to put on our speculation hats. In the US, the base car is about 81 percent of the price of the 350-horsepower S model. If Porsche were to offer the same discount for the hypothetical, 250-hp 718s, it could set the starting prices at $43,659 for the Cayman and $45,360 for the Boxster. That lines up neatly with the $43,500 TT Coupe, but this theoretical 250-hp Boxster would fall about $1,640 less than Audi's soft top. We shouldn't forget Porsche's expansive options catalog – we doubt there'd be a lot of sub-$50,000 718s on dealer lots. But still, slashing over $10,000 off the price of a $54,000 car is a big ask – Porsche would almost have to de-content such a lower-tier model. But – and this is a Kim K-sized but – moving the 718 downmarket would open the brand to a new range of consumers. Not only would these new cars be the cheapest sportscars from Porsche money could buy.

2017 Audi A4: Allroad vs. sedan: We explain the differences

We're rotating 2017 Audi A4 models through our long-term fleet. First came the sedan, followed by the Allroad. They briefly overlapped in our garage. The Allroad is a slightly lifted 'estate' version of the sedan, but the differences go beyond that. We go into great depth in the video above. As you'll discover, there are small tweaks to the trim and styling, and larger changes involving the cargo space and pricing. Michael Austin and John Beltz Snyder explain it. Still need more info?
