Assuming everything else is equal (vehicle size, weight, driving style, tires), how do you make ICE engines be more fuel efficient? I noticed my dad’s 1996 Nissan Pathfinder V6 consumes 13L/100km (mixed driving) while a newer V6 is 9L/100km. Car manufacturers claim their engines are “more fuel efficient”, how do they accomplish that?

Alright, little buddy!
Step 1: Imagine your engine is like a person who eats food.
Step 2: Sometimes, the person eats too much or wastes food.
Step 3: To make an engine more efficient, we want it to use all its “food” (which is fuel) without waste.
Step 4: We can do this by making better engine parts, and designing them to work smoothly together.
Step 5: When the engine uses its fuel better, it’s like a person eating just the right amount of food and feeling strong!
