I have a dilemma. I'd set up a ship (it's a couple of centuries old) as an Ion drive ship and now my brain is exhausted trying to recall what would be faster. I think FTL is the way to go but what about the mechanics of it should I need to explain the newest ship in the fleet? This new, super sleek ship will be my protagonist's ride when she's not hopping in and out of the past. (It is not the Waverider, so it won't be going through time with her. It gets her from place to place in the present.)

MPD (Magnetoplasmadynamic) thrusters could potentially be faster than ion thrusters because, in theory, they would produce extremely high specific impulses and propel your ship up to about 110000 m/s, which is around three times the top speed of current xenon-based ion thruster systems.
They would also drastically increase the fuel efficiency of sharp delta-v maneuvers.
