I would say Xdiox is correct. Any grav vehicle can get to and from orbit, it may take a while and required the craft either be pressurised or the passengers wear vacc suits.
To calculate space performance of a grav vehicle, divide the top speed by 1080. This give acceleration in Gs, to compare to the acceleration of Starships. So while you can get a grav vehicle to fly to and from orbit, its usually much better to take a spaceship.
