Nice shot, but unfortunatley the car looks like it could be stopped on the track, waiting for the green flag... it lacks a sense of "speed", other than knowing that this car CAN go fast.
I'm sure this guy was moving fast but your equally fast shutter speed has frozen the motion. I would have preferred some motion blur to show the concept of speed.
You needed to be closer to the subject really, or shoot it as it passes you at the nearest point, which would give you more peripheral 'motion blur'. An off-centre subject could have improved it too (car to the right - suggesting it's passing fast). [4]
