What impact or difference is there between impulse engines that are efficient at low vs. high power levels.

I really do not understand this language and how it impacts the device in-game.

As I understand it, efficient and combat impulse engines yield a higher top speed at low power levels and increasing power levels has a minimal impact on overall speed. Hyper impulse engines yield the highest top speed at high power settings.

So in general you want combat impulse engines since most of the time in combat your going to have your power going to weapons or shields not engines.

combat gives you better steering and more efficient lower power turning, but once you get to fullpower, you can be outrun by hyper and standard impulse.

This is something I'm currently looking into, but based on what I've seen so far:
  • Combat Impulse engines lose less speed at low engine power settings, but also gain less speed at high engine power settings
  • Hyper Impulse engines lose more speed at low engine power settings, but also gain more speed at high engine power settings
  • Normal impulse engines are in the middle, losing a moderate amount of speed at low engine power levels and gaining a moderate amount of speed at high engine power levels
In addition, Combat engines tend to have slightly higher turn rate bonuses, and Hyper engines tend to have higher Full Impulse speeds.

Like I said, still working on this, so can't give you any specific numbers yet.

I will experiment, that you for this post. Very helpful.

Not necessarily. The difference isnt's that much between a Combat Impulse Engine and an Impulse Engines at lower power at the usual 25 that most people run. With Mk IV engines the difference is like Impulse 13 vs Impulse 16. I suggest that you try things for yourself to see if it makes a big enough different for you.

Oh and FYI: That delightful blue Efficient Impulse Engine Mk IV you can get as a reward from the City of the Edge of Never mission? It's a Hyper Impulse Engine as well. I compared the Efficient Impulse Engine vs a blue Mk IV Hyper Impulse Engine. They had identical speeds at all power levels.

Edit: The distinction between high power and low power seems to be power allocation level of 75. 75 and higher is considered high power, Less then 75 is considered low power.

I want to know my power level stats with Hyper Impulse Engine Mk X at subsystem engine power levels 25, 50, 75, and 100. But mainly 75 and 100. What would my total engine power be at those levels? (aka: ??/75 or ???/100)? And tell me if [Full], [Aux], [Turn], and I think there is one more I'm forgetting, effects these outcomes.

Thanks. I'm planning on establishing a good Escort "Hit-and-Run" build, utilizing the Weapons and Engine Subsystem powers (with the new patch, it will help turn rates as well). I want a high speed so that it will add to bonus defense. It effects enemy accuracy which can tremendously benefit the weak Escort. I have tested speed and noticed that the defense goes up as it is increased, as most people know. I have not tested if turning effects the bonus even beyond this so if anyone can place an input on that it would be most appreciated. If Turn rates help, then RCS Accelerators might be appliable. Also any consoles (eng, tac, or sci) that could help with Bonus Defense ratings or increased speed would be appreciated as well (Injectors are one example console). Remaining Consoles will affect weapon damage and transfer rates (EPS Flow Regulator is probably a must).

Subsystem Power is pretty annoying to figure out. I'm thinking I should go (example: weapons/shields/engines/auxiliary) 100 / 25 / 50 / 25 but if I really want my defense bonus, I'm gonna have to do 75 / 25 / 75 / 25. I might be switching between the two alot.

You are confusing two different things. You power level stats are displayed in you power contol area. There is the base power allocation (number on the right of the ''/' I.e. */25 or the yellow part of the bar graph) and the net power setting (base + bonuses). The number on left of the ''/' (i.e. 45/*) or the yellow (base) + green (bonuses) of the bar graphs).

You net engine power determines your maximum speed at full throttle. (The SPD stat). The different engines have different behavrious. The normal Impulse Engines have a linear max speed to power setting ration. Combat Engines have a skewed max speed / power setting. When the power setting is low (i.e. lower then 75). I don't know the exact curve, but I suspect that the lower the power the more skewed the curve it. That means that Combat Impulse Engines will have a higher max speed then the other engines types. Hyper Impulse are just the opposite. Their max speed to power setting is skewed when the power setting is high (higher then 75). That means that Hyper Impulse engines have a higher max speed at high power settings then the other two types.

Those comparissons assume identical engines other then the types (Hyper, Combat, etc). If you Engine power is going to be in the middle power range say 40-60 , no engine will have a better max speed then any other the others. (I haven't tested it, but the normal impulse engine may have advantage.) You can determine your current speed by hovering the mouse pointer on top of the bar of of the throttle. Your current speed will show as a tool tip.

The extra attribues of the engines boost that parotuclate stat for the engine. SPD means the top speed of the engine is increased over a like non SPD engine. SPDx2 means you move faster still. And if you want to have the full story about Ship's Power, read my Ship's Power Guide. Link is in my sig below.

@ Orion_Starchaser: If you want to see the effect of changing your power settings, when you are in a sector, increase your impulse speed and then change the Engine power setting. The chages are real time, so you'll see your speed and turn rate change as your engine setting goes up and down.
