Gaming blog Kotaku, who visited Rockstar Games yesterday for a single player hands on of GTA IV, revealed today that they were informed by R* that the recent trailer consists 70% of actual game play footage. Most notably the impressive chase scene where the car turns a 180 at high speed.
"During my visit with the Rockstar folks yesterday they told me that about 70 percent of the video was actual gameplay footage. Yes, that chase scene is actual footage. It took one of their guys hours to perfect that high-speed 180."

Just to be clear, the trailer is still cinematic because the build that they have internally comes with several tools for creating the trailer, amongst other things, such as using the built-in detachable camera and freezing the game at any point. Kotaku also promises to have a preview on their single player impressions up soon.
