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 SQ7 coming, will have electric turbo

Formula 1 and endurance racing are already harvesting energy from turbos on the track, and now it's apparently time for a similar idea of boosting the efficiency of forced induction to hit the streets in a high-performance, diesel SUV.
In a recent interview with the UK's Autocar, Audi technical boss Dr. Ulrich Hackenberg let the big news slip. "The new Q7 will be available in the market next year but the electric turbo will come a bit later in the Audi SQ7 available in 2016," he said. The e-turbo system was already rumored for the premium SUV but for the standard model, not this just-announced performance version.
Audi has been experimenting with the e-turbo system for a little while, as an electrically driven supercharger. It showed up on the RS5 TDI concept that used a 3.0-liter, twin-turbocharged diesel V6 plus the electric system to diminish turbo lag. In that application, it provided an impressive 385 horsepower and 553 pound-feet of torque and an alleged sprint to 62 miles per hour in 4 seconds. Although, Dr. Hackenberg didn't make it clear if this was the exact layout for the SQ7.

The 2018 Audi RS3 sedan priced above the BMW M2 and Mercedes CLA45 AMG

Today, Audi finally released pricing for the 2018 RS3 sedan and it's not quite the performance bargain you may have been hoping for. The RS3 sedan, available for the first time in the US, will start at $55,875 when it hits dealer lots later this year. That's thousands more than the competition from BMW and Mercedes-Benz, though it's not quite a straight one-to-one comparison. View 23 Photos For reference, a BMW M2 starts at $53,495 while a Mercedes-Benz CLA45 AMG will set you back at least $50,875. With an all-new 400 horsepower inline-5 under the hood, the RS3 is packing more punch than its German rivals, and, unlike the M2, sends power to all four wheels. Standard features include LED lighting, Audi pre sense basic, and blind-spot monitoring. Other standard equipment hasn't been announced yet, so it's difficult to make a straight comparison to the M2 and CLA45 AMG. The RS3 sedan will make its North American debut next week in New York. While the car will hit full production for the 2018 model year, there will be a limited number of 2017 RS3s produced. At $55,450, the 2017 model is slightly less expensive than the 2018 RS3. That small batch will be preconfigured with carbon trim, Audi virtual cockpit with MMI Navigation plus, a Bang & Olufsen sound system, 19-inch, five-arm-blade design wheels, red brake calipers, and the RS sport exhaust system with black tips. Sounds like a good deal if you've already got your heart set on the latest from Audi Sport. Related Video:
