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.

Delphi plans automated-driving journey across the United States

Delphi is attempting to become the first company to pilot an automated car across the United States. The global automotive supplier will start a cross-country journey from a location near the Golden Gate Bridge in San Francisco starting on Sunday, March 22, and cover approximately 3,500 miles on a trip to New York, where it will arrive sometime during the New York Auto Show. Along the way, Delphi engineers will gather data on how the car, an Audi SQ5, performs in a variety of road and weather conditions that the company says could only be tested in a real-world environment. "Delphi had great success testing its car in California and on the streets of Las Vegas," said Jeff Owens, the company's chief technology officer. "Now it's time to put our vehicle to the ultimate test by broadening the range of driving conditions." A formal announcement is expected tomorrow during the SXSW festival in Austin, TX. The company recently demonstrated many of its advanced-safety and automated driving technologies during CES, driving in Las Vegas. The cross-country trip will include tests on its radar, vision and advanced-drive assistance systems, certain vehicle-to-vehicle and vehicle-to-infrastructure communications, and intelligent software, which includes automated highway pilot with lane-change technology, automated urban pilot and automated parking functions. Though a driver will be behind the wheel throughout the journey, Delphi says its active safety technologies can make complex decisions, like stopping and proceeding at four-way stops, timing highway merges and calculating safe maneuvers around bicyclists. While California has certain motor-vehicle laws that help regulate autonomous vehicles, it was unclear whether Delphi needs special arrangements or permission from other states to conduct automated-vehicle testing elsewhere – or if those concerns might be negated by an active driver. Earlier this year, Audi turned heads at CES by driving an A7 from San Francisco to Las Vegas in a similar display of automated-driving technology.

Mazda3 versus BMW 1 Series and Audi A3 in Euro diesel showdown

It's not exactly a Tesla Model S taking on a Ferrari, but for us green enthusiasts, a drag race and comparison between reasonably priced diesel hatchbacks does hold interest, and UK's Auto Express was kind enough to do the deed. When raced, the diesels actually laid a little rubber coming off the line, though the track was covered in rain. Did we mention it was in the UK? The comparison was between diesel hatchbacks priced at less than 22,000 British pounds (about $34,500 US), and Auto Express pitted a Mazda3, a BMW 1-Series and an Audi A3 against each other. The results are revealed in the 11-minute video you can watch below. In short, one car smoked the others. In order to set the tone, you should know that the Mazda's 150 horsepower is about 35 more than the other two entrants. The Mazda also earned points for its quiet motor (it sounds more like a petrol engine, the host says), standard equipment that would add about $4,000 to the other two cars if included and relative roominess in front and in back. The Audi gained points for its storage space, while the BMW had the only rear-wheel-drive car in the hunt. See for yourself how the competition stacks up.
