| Transwarp Drive | Beats all other engines at speeds of 48ly+. Still excellent at lower speeds, though Tylium Thrusters and FTL-4 Warp Drives are slightly better.
|
| FTL-5 Warp Drive | Only alternative to Transwarp Drive for speeds of 111-120 but burns 2-3x the fuel. Compares favorably to the FTL-4 Warp Drive for speeds of 61-110 where both compare more favorably to the Transwarp Drive as speed falls (rapidly drops from 3x to 1.5x the fuel burn at a speed of 95ly). At speeds of 60 and below, fuel burn jumps back up to 2-3x both FTL-4 Warp Drive and Transwarp Drive.
|
| FTL-4 Warp Drive | Second only to the Transwarp Drive for speeds of 48-110. For speeds of 31-48, this is the most fuel-efficient engine, followed at a close second by the Tylium Thruster. The Transwarp Drive very closely trails them both. Efficiency matches the Tylium Thruster and Lazar Drive for speeds of 28-30. Below a speed of 28, the Tylium Thruster wins out.
|
| FTL-3 Warp Drive | Better than the Tylium Thruster for speeds of 53-105; worse for speeds of 52 and below. Better than the Turbo Thruster for speeds above 40. Equivalent to Turbo Thruster at lower speeds. Better fuel-efficiency than the FTL-1 Warp Drive and FTL-2 Warp Drive.
|
| FTL-2 Warp Drive | Better than the Tylium Thruster for speeds of 53-100; worse for speeds of 52 and below. Better than the Turbo Thruster for speeds above 40. Equivalent to Turbo Thruster at lower speeds. Better fuel-efficiency than the FTL-1 Warp Drive.
|
| FTL-1 Warp Drive | Better than the Tylium Thruster for speeds of 53-90; worse for speeds of 52 and below. Better than the Turbo Thruster for speeds above 40. Worse than Turbo Thruster at lower speeds.
|
| Lazar Drive | Equivalent to the best engines when traveling at speeds of 16-30. Engine efficiency at speed 16 exceeds the efficiency at speeds 4-15.
|
| Scalar Wave Thruster | Burns 2-3x more fuel than the Tylium Thruster Roughly equivalent to the Turbo Thruster at at speeds of 21-40. Worse than Turbo Thruster at lower speeds.
|
| Energy Conversion | Falls only slightly behind the high efficiency engines except near the half- and quarter-speed marks, where it experiences a 3x spike.
|
| Tylium Thruster | An extreme fuel hog at speeds of 52-105, burning up to 7x what a more efficient engine would. Performs much better at lower speeds, comparing very favorably against the FTL-4 Warp Drive and Transwarp at speeds of 27-52. At even lower speeds, the Tylium Thruster is the most fuel-efficient engine around.
|
| Turbo Thruster | At speeds of up to 40, the Turbo Thruster burns around 2x what a more efficient engine would. For speeds of 41-80, it is a fuel hog, though it is considerably better than the I-series Impulse engines.
|
| Electrogravitic | While much better than anything of lower tech, the Electrogravitic burns at least 1.5x more than the higher tech, high-efficiency engines. At speeds of 1-20, the fuel burn jumps to 3-4x that of the best engines.
|
| I-25 Impulse | Better than anything of lower tech, it burns 2-4x the fuel that an Electrogravitic would.
|
| I-20 Impulse | Slightly worse than the Lasno Ion Drives at speeds of 11-20. Otherwise better than anything of lower tech.
|
| I-17 Impulse | Slightly worse than the Lasno Ion Drives at speeds of 11-20. Otherwise better than anything of lower tech. Has slightly better fuel-efficiency then the I-20 Impulse at speed 11.
|
| R50 Mega-Fusion | Beats N30 Fusion Drive at speeds of 1-7, and is slightly worse at speeds of 8-15. Beats Lasno Ion Drives at speeds of 1-7, and is much worse at speeds of 8-15. Better than N20 Fusion Drive.
|
| Lasno-2 Ion Drive | Best of low-tech engines, at speeds of 11-20, until the Electrogravitic. The I-series Impulse engines beat it out at lower speeds and all other engines, except the Lasno-1 Ion Drive, beat it out at speeds of 1-5.
|
| Lasno-1 Ion Drive | Compares to the other low-tech engines in the same manner as the Lasno-2 Ion Drive, though it burns up to 1.5x the fuel.
|
| N30 Fusion Drive | Slightly better than the R50 Mega-Fusion and better than the N20 Fusion Drive. Better than the Lasno Ion Drives at speeds of 1-5.
|
| N20 Fusion Drive | Better than the Lasno-1 Ion Drive and Lasno-2 Ion Drive at speeds of 1-5.
