In this video guide I will show you how to jump over 100 meters with a ground vehicle. Once you are able to get into free roam and get your phoenix you can get this. No upgrades required to obtain this either. Just head to where I am at on the map which is north of one of the enemy bases to capture. Once you see the ramp head down the road and turn around. Make sure to drive straight as possible and keep heading towards the ramp. If any vehicles get in the way just start the run over again. Once you get to the concrete by the ramp DON"T USE TURBO YET. You need to wait until you get over the little bump transition from the dirt road. Once over it use as much of the turbo as you can even when in the air. If you flew far enough the achievement will pop. If you didn't get it just retry until it does.
