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.

Entry-level Audi R8 to go turbo after all?

Would you be shocked if we told you that the better version of the Audi R8 offered a V8 engine rather than a V10? There was something inherently lovable about the company's 4.2-liter V8. Maybe it was the noise or the high-revving nature or some combination of the two, but the R8's original engine is a darn hoot. Sadly, the V8's days appear numbered in the brand's flagship model, according to a new report from Car, which claims Audi will ditch the beloved, off-angle 4.2-liter for a 2.9-liter, twin-turbocharged V6. The rumor cites sources in Ingolstadt who claim the new engine will develop 450 horsepower, up 20 ponies on the current entry level engine. We'd expect a commensurate increase in fuel economy too, befitting of a smaller, force-induced engine. Still, this is counter to what we've heard before. But, if the report proves true, the R8 will join the ranks of turbocharged supercars like the Ferrari 488 GTB and California. It's unclear when such a switch would be made, but according to Car, we can place the blame squarely on China. The country has been combating large-displacement engines since 2008, attaching massive taxes on vehicles with anything larger than a 3.0-liter engine. It's China's position, Car reports, that led to the death of another beloved, naturally aspirated V8, Mercedes-AMG's 6.2-liter model. First the venerable M156 and now Audi's 4.2-liter V8? Just stop this silliness China. Related Video:

2016 Audi S6 Quick Spin [w/video]

Back in my salad days, when I was rocking a the greatest Civic Si of all time, the occasional pair of leather pants, and a yen for malt liquor and grass (both of which quickly put an end to the leather pants), a car like the 2016 Audi S6 would've made my head explode. "What's that?" I might have asked. "A roomy four-seat Audi with more than 400 horsepower and all-wheel drive, that looks like it was sculpted by Ralph McQuarrie? Pushing 30 mpg and under five seconds to 60 miles per hour? The hell you say." And that's even before Future Me showed Skinny Me an interior full of carbon fiber and aluminum, God's own quilted-leather sport buckets, and a 'radio' that would've made my Dreamcast look like an Atari 6400. (If you haven't picked up on the vibe yet, I was kind of a weird nerd in the late '90s.) Gentlemen, we live in the future; I just drove a mid-cycle-refresh Audi that proves it. Driving Notes The 4.0-liter, turbocharged V8 is tailor-made for smoothly pulling around anything less-well-endowed than the M5/E63/CTS-V set. Now up to 450 horsepower and 406 pound-feet of torque (versus the 420 hp and 406 lb-ft of last year's model), there's enough pull in the easily accessible powerband to satisfy all but lunatic drivers. It doesn't feel staggeringly fast, but that's only because 500 horsepower has become so commonplace in the new uber sedan game. It's quick enough. Remember when 250 hp was a crazy number? The car sounds like it has a V8, too. That may seem obvious, but in Generation Direct Injection things tend to get a bit clattery. You'll get some of that if you open the hood with the engine running (as I did in one of the Short Cuts above), but none where it counts: behind the wheel, windows up, stereo down, foot to the floor. That recipe delivers a hushed, baritone-sung song about understatement. Less subtle is the braking force when used at or near the top of its ability. After a moment of surprise and delight while decelerating in normal traffic, I went back-road hunting to test a few pseudo panic stops. Vented 15.7-inch front discs, with 14-inchers in the rear, provided a fast and steady haul-down from 70 miles per hour. Remember when wheels were 15 inches? I mean, you need those big brakes and potent engines to move and stop a car this hefty. With a base weight of 4,486 pounds – no doubt heavier still in my loaded, Dutchman-driven example – it still kind of blows my mind to see the 27-miles-per-gallon highway number.
