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.

Recharge Wrap-up: Chevy Spark EV in Canada, Audi to use Valeo electric supercharger

The Chevrolet Spark EV will become available to retail customers in Canada. "We're expanding our electric vehicle offerings to our customers by offering the 2016 Spark EV for retail sales in the growing EV markets here in Quebec as well as in Ontario and BC," says Chevrolet's Chris Hay.

Four recreational vehicle companies in Texas have settled with the EPA over illegal import and sale of off-road vehicles. The 4,000-plus Hammerhead brand vehicles in question were imported without the proper certification, a violation of the Clean Air Act. Some vehicles lacked proper emission control equipment or were manufactured by a company not listed on the certificate application. The settlement totals $560,000 in civil penalties for the companies involved. Read more from the EPA. The Iowa Supreme Court has upheld the state's natural gas tax, which was challenged by the ethanol industry. Ethanol producers, which use natural gas to make ethanol, argued the complicated tax was unconstitutional, as it forced certain plants to pay more than their competitors. Taxes vary by location, and some plants have to tap into interstate pipelines at much higher tax rates rather than get it from a local utility. Now, ethanol producers will work to change the law. "My hope is that people understand that, something may be constitutional but that doesn't make it good public policy," says Iowa Renewable Fuels Association Executive Director Monte Shaw.

Valeo says Audi will launch a vehicle using its electric supercharger next year, with other reports suggesting that car will be the Audi Q7. The company says other unspecified automakers will also use the technology in their vehicles. While the electric supercharger adds to the vehicle's cost and electric energy use, it can improve fuel economy by as much as 20 percent. Read more at Automotive News Europe.

Audi RS3 Sportback is the hottest hatch

Fans of compact, European vehicles that mix luxury and performance should be in paradise right now. There's already the 320-horsepower M235i from BMW and the 355-hp CLA45 AMG (or A45 elsewhere) from Mercedes-Benz, but you can now add one more to the list. Meet the Audi RS3 Sportback, which boasts 362 hp and five doors, too. With propulsion coming from Audi's turbocharged 2.5-liter five-cylinder that makes 343 pound-feet of torque (465 newton-meters), the RS3 Sportback can scramble to 62 miles per hour in 4.3 seconds. Top speed is limited to 155 mph, but buyers can opt to raise that top end to 174 if desired. The inline-five is mated to a seven-speed S-tronic dual-clutch gearbox, sending power to the ground via Quattro all-wheel drive with torque vectoring, which can send between 50 and 100 percent of the power to the rear wheels as needed. To cope with the boosted output, the suspension has been lowered by an inch compared to the standard A3 Sportback, and magnetic dampers are a further option. Buyers can also tick the box for carbon-fiber-ceramic brake rotors at the front. The RS3 goes on a diet its latest iteration, too, weighing 121 pounds less than its predecessor. While buyers get potent power, Audi keeps the looks understated. The exterior wears a front airdam with larger openings and some aluminum flourishes, and a diffuser at the back gets some more matte trim. A roof spoiler and aluminum look for the mirror housings add a few other touches to catch the eye. Inside, all versions get sport seats covered in Nappa leather and a flat-bottom steering wheel wrapped in leather and Alcantara. But for the really sporty look, buyers can spec optional RS buckets with a carbon shell that weigh 15 pounds less than the standard units. European deliveries of the RS3 Sportback begin in the summer. Autoblog reached out to Audi spokesperson Mark Dahncke who told us there are currently "no plans to bring it to the US." Scroll down to read Audi's full announcement of this five-door hot hatch.
