How do I make a car go jump over a ramp?

[BatmanX12]

Like My car drves right through the ramp, and when I try to jump, the car stops and jumps. So how do I make the car without stopping to go over the ramp and jump (just like those old movie where a car drives fast and jump across).Like i know there has to be a way for the car not to go through the ramp.
