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.

Next Audi TT glimpsed, same as it ever was?

Audi has teased the new TT coupe ahead of its Geneva Motor Show reveal with renderings and video, but now, what appears to be a photo of the new two-door has leaked onto the web, courtesy of Autofans.be. And if you're thinking, "Well, jeez, that looks familiar," you definitely aren't alone. Aside from the new lighting character in the taillamps, everything you see here looks pretty much unchanged from the old car. Of course, the front should get a nice freshening, and that interior should be super-high-tech. We'll reserve final judgments until we see the new TT live in Geneva next week.

How Audi will make roads friendlier to autonomous cars

Today, Audi announced some of the new projects it will be implementing on Germany's Digital Motorway Test Bed, which comprises a few sections of highway on which the government and industry can test autonomous and connected tech. Among Audi's projects is one specifically aimed at making roads easier for autonomous cars to navigate. Audi is looking to make the road and other objects more visible. The company has been researching materials that could make guardrails and road markers reflect radar waves more readily, and Audi will install test versions soon. The goal here is to help make these objects easier for the autonomous vehicle's sensors to see in inclement weather, and at greater distances in good weather. The company will also test additional road markings that will be easier to see for onboard cameras and will help the car place itself on the road. Audi will also try out new vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology that will be able to alert cars to speed limits, traffic conditions, ice patches and possibly allow for driving patterns such as platooning. This will be a significant step above the traffic light communication system Audi has released in select areas. The company will also be working on very detailed mapping of the area. Audi claims it will be accurate down to the centimeter. From what we've seen at MCity, the world as it stands presents all kinds of difficulties for autonomous vehicles, from worn-out signs to rough pavement. So any advances that make it easier for autonomous cars to see and communicate should help bring such vehicles to reality much sooner.
