Turn 10 has revealed some new details for Forza Motorsport 4 in a feature on the MSN Autos site, explaining how the developer is taking the realism further by scanning vehicles - such as the oh-so tasty Bugatti Veyron - with 3D lasers to map every minute curve and detail. There's also some insight offered into the game's tyre behaviour and Kinect-tracking capabilities.

Collaborating with tyre manufacturer, Pirelli, Turn 10 is hoping to provide the "most up-to-date simulation of how modern tyres grip or slip in a variety of racing conditions". Extra lengths are even being taken in replicating its versions of real-world tracks, with each circuit being painstakingly recreated using terabytes of data including captured videos and images, as well as tracings of the surfaces spanning the track taken with a GPS system.

This will allow for "road crowning, tiny changes in camber or angle, and other anomalies with subcentimeter accuracy," meaning that the tracks are likely to be the most accurate and authentic yet seen in a racing game. Blimey.

As for the level of support that will be offered for Kinect, Forza 4 will have "limited functionality" including a "phantom steering wheel" that you'll grasp and use to tackle corners, alongside head-tracking for peering around blind curves as you lean to edge the driver's view. This can also be used to look around a car as you pass during an overtaking manoeuvre. You'll be able to "walk around" Forza 4's cars and poke around the interior as touched upon in the E3 2010 demo too.

"I think we're just scratching the surface," Turn 10's Dan Greenawalt said of Forza 4's Kinect support. "I have the feeling that we'll all look back at these first few years of Kinect and reflect on it as a huge inflection point in interactive entertainment."

Forza Motorsport 4 is lined up for release later this year.
