In total there are 45 Long Jump Locations in Need for Speed Unbound and successfully completing all the jumps with a 3-Star rating will unlock the Nissan 370Z Nismo '15. It will also unlock the Frequent Flyer and Cleaning Up achievement/trophy which requires 100% completion of the game.
The Long Jump activities start to become available after you have completed the prologue during the story (or immediately if you play online). The jump itself will have a ramp which you will need to use to reach a specific distance traveled in the jump to earn the star levels. Keep in mind most of the jumps have paths that lead up to them which means you can make your way back up to the end of the path before attempting the jump.
Take a look at the video below to see how you can perform all the jumps with 3-Stars and Rival Scores Beaten.
