Audi testing long-tail version of R18 e-tron quattro for Le Mans

Race teams are always looking for ways to shave hundredths of seconds of their lap times. Case in point: Audi is making some slight changes to its prototype racecar to make it ever so much more slippery as it cuts through the air.
Debuting at the second round of the FIA World Endurance Championship at Spa on May 4, Audi will be testing a long-tail version of its R18 E-tron Quattro racecar. As its name suggests, the long-tail car gets a lengthened rear section with the goal of improving aerodynamics. The long-tail will be run alongside the standard version of the racecar as a testbed for possible changes that might be in store, heading into the 24 Hours of Le Mans.
Audi did not say how many inches were added to the racecar, but as you can see in the image above, "long-tail" definitely doesn't take on the same meaning of classic long-tail cars of the past such as the Porsche 917. More information about the car, Audi's team and even some info about the track itself can be found below.

Auto Express gets close-up look at the 2016 Audi R8

Audi invited Auto Express to the Ascari circuit in Spain to get a ride in the new R8 that will be introduced at the Geneva Motor Show. Jack Rix starts by giving us a walkaround of the camouflage-covered coupe, the obvious difference between it and the leaked image from a couple of weeks ago being the slatted front intakes. However, those intakes are present on the image Audi teased showing off one new, slimmer, laser headlight. The biggest shock: there will be no V8 model at launch - there will be one engine in two levels of tune. The first is the 5.2-liter R8 V10 with 540 horsepower, a bump of 15 hp over the present car. The second is the 5.2-liter R8 V10 Plus with 610 hp, a leap of 60 hp over the current model. That hotter trim, identified by its fixed rear wing, drops the 0-60 mile per hour time by a half-second to 3.2 seconds, and increases top speed seven miles per hour to 205 mph. Rix ran his fingers along the intakes behind the door and said he could feel sideblades, so all is not lost - what would an R8 be without sideblades? More obviously, on the V10 Plus Rix looked over there are new trapezoidal exhaust tips framing a serious diffuser in back. Underneath, the aluminum chassis adapted from the Lamborghini Huracan is 15 percent lighter than before and 40 percent stiffer. Shifting will be done via a seven-speed S-tronic dual-clutch transmission only. There are seven driving modes, a switchable exhaust note, and more direct variable steering. The German test driver Rix rode with said the new R8 is easier to drive faster, which - no matter what you think of the looks - will make it pretty special.

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.
