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?

That you think that is efficient is laughable.
“The UK’s average new car fuel consumption in 2020 was 52.6 miles-per-gallon (mpg) (5.4 litres per 100 km) for petrol vehicles and 56.1 mpg for diesel vehicles (5.0 litres per 100 km).”
You make things efficient by removing weight, increasing aerodynamics (make things smaller), controlling the engine better (ECU etc.) and having a smaller engine (the Ford Mondeo in the UK is the same car as the Fusion in the US… in the US it *starts* at 2.5L, in the UK the largest you can get is 2.0L and it starts at 1.5L).
Stop burning dinosaurs just to carry around tons of metal that do nothing. It doesn’t even make your cars any safer.
