Dual-Stage 4 Grid Ion Thruster

The DS4G is the most advanced ion engine in the pack in terms of fuel economy. It runs on Xenon Gas. It is possible to attain in the hundreds of km/s of delta-v with a small probe. Its large energy use means that a nuclear reactor is the most effective power source for it.

Description
"The DS4G is an advanced electrostatic engine. Four grids must be better than one, right? Immense fuel economy with low thrust means that this guy will be great for clustering or for probes."
