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.

Audi confirms Q8, electric CUV in the works

Word got out in late 2012 that the Audi Q8 was reportedly approved for production, but the company has kept the model's development under wraps since then. In a recent speech during Audi's annual meeting, chairman Rupert Stadler confirmed a little more about the vehicle and dropped some hints about other upcoming projects. With luxury crossovers remaining a lucrative market, it should be no shock that Stadler emphasized them in his speech. He reiterated that the Q1 was on track to launch in 2016, and the chairman also confirmed the Q8 as "a sporty Q derivative" that's on the way. The last member of Audi's upcoming CUV onslaught, an electric Q series, is set for 2018 with a range of over 311 miles. An earlier report suggests that the Q1 might not go on sale in the US because it's not right for the market. However, Audi of America is pushing hard to get the Q8. That crossover is based on the latest Q7 (pictured above) and is a way for the Four Rings to take on the BMW X6 and Mercedes-Benz GLE Coupe. The electric Q model was only officially announced earlier this year, and it might use 90-kWh batteries to achieve its performance and range goals. The rest of Stadler's speech focused on the company's future. This year alone, the company is launching products like the second-gen Q7, the new R8, and latest A4. In the next five years, Audi plans to grow its product range from 52 vehicles "to about 60 models," according to the chairman. Rupert Stadler, Chairman of the Board of Management of AUDI AG Neckarsulm, 2015-05-22 Speech at the 126th Annual General Meeting of AUDI AG Outlook Thank you, Axel Strotbek, for your summary of financial year 2014. Ladies and gentlemen, that brings us to 2015 – the year of the next stage of our model initiative. We will present twelve new Audi models this year; the three most important of them are: the new Audi Q7, the new Audi R8 as the sporty spearhead of our brand and our top seller, the new Audi A4. You have already been able to admire the new Q7 and R8 at the entrance. Both of them make a strong statement. Both of them stand for sportiness and top premium quality. And both of them underscore our claim to leadership. We have produced more than 540,000 of the first-generation Q7. The new Audi Q7 is more than a worthy successor. It's the lightest vehicle in its segment. By means of intelligent lightweight construction, we have reduced its weight compared with the predecessor by up to 325 kilograms, depending on equipment levels.

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.
