Tom Kristensen walks through a perfect lap of Le Mans in Forza 5

One of the best ways of learning a new track, aside from driving it, is to hear someone that's intimately familiar with it give you a good walkthrough. That's just what you'll get here, as the winningest driver in 24 Hours of Le Mans history, Tom Kristensen, walks you through the Circuit de la Sarthe's high-speed, 8.5-mile strip of pavement.
Kristensen is dubbed over scenes of drivers from a Forza Motorsport 5 contest lapping the track at the wheel of an Audi R18 E-Tron Quattro, adding a bit of visual sense to the Danish drivers description of the track.
With the 2014 24 Hours of Le Mans kicking off this weekend, this is just the sort of video you'll want to watch to get you in the mood. Take a look below, and then let us know what you think in Comments.

2016 Audi A8 L 4.0T Sport bridges the gap to S8

Want to get your hands on an Audi S8, but can't quite make the stretch? You may be interested, then, in the newest addition to the A8 family. Because it just may be the next best thing. As the moniker suggests, the 2016 Audi A8 L 4.0T Sport packs a similar 4.0-liter twin-turbo V8 to the one in the S8 (and the Bentley Continental GT for that matter). But instead of 520 horsepower, it's tuned to produce a somewhat more modest 450. That's also less than the 500 hp offered in the W12 model, but then the V8 engine is a fair bit lighter, and it produces 15 more horses than the previous 4.0T model. Along with the upgraded engine comes a sportier look, with larger air intakes at the front, more sculpted side sills, and 20-inch (or available 21-inch) alloys. It also comes standard with the Executive and Luxury packages, complimented by diamond-quilt stitching, and a headliner upholstered in Alcantara with a panoramic sunroof. Of course, it's also priced a fair bit lower than the aforementioned more powerful versions: $90,500 (plus $925 destination) is a relative bargain compared to the $114,900 commanded by the S8 and $137,900 for the A8 L W12. Audi has yet to release performance figures, but we'd expect it to drop a tenth or so off the 4.4-second 0-60 sprint achieved by the previous, 435-hp model. Those looking for more power than the S8, not less, may still hold out hope for the S8 Plus with its 605 hp to make its way to US showrooms.

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.
