Since balancing gasoline versus diesel engines isn’t something most people think about, I think I came up with a clever solution. Currently in-game, diesel engines’ fuel tanks have the ability to act as spall liners, preventing all primary spall from a penetration. This means that solid shot often fails to even harm the target, with the worst of the damage consisting of a fire that must be extinguished. Although gasoline fuel tanks can possibly do the same thing, they often fail to do so.
So how do we create some asymmetry in favor of gasoline engines? The answer is the smoke!
Diesel engines in real tanks often have thicker exhaust clouds, especially on engine startup. This can be used to passively affect the visibility of a vehicle. If diesel engines received a more opaque or white cloud of exhaust, or gasoline’s exhaust became more transparent, this could be accomplished very easily. Essentially, diesel engines with their attractive power and spall-liner-like fuel tanks would be slightly more visible at a distance. This would give gasoline driven vehicles a slight advantage in being able to hide (especially from CAS).
