I think that it is not necessary to change the parameters of those drives that are already in the game. With the exception of the fuel consumption parameter, it needs to be adjusted: if I understand correctly, even when the drive is running at only 10%, it burns almost as much fuel as if it were running at 100%. Too many ships have already been built by players, if you significantly change the parameters of the drives, it will cause problems. I think we need to add new drive models and make it so that the old models remain competitive
