Large engine = large consumption??

Hello, I always ask myself the question if a car with a lot of ps/cm3 really consumes more than a car with less PS/hubroom. A low-performance car you have to press constantly to get ahead with it. Best example highway: First it is very cumbersome to get the car to speed so you can drive on the AB and second the overcrowding process with a 70 PS gulf is in my opinion very uncomfortable! You almost need a start to be able to overcrowd safely. n 70 hp car with a 100 hp or 150 hp (you don’t really need more!) compare car, would the 70 hp car always have to pay the most on the motorway at approx. 130 KM/H. Would the consumption be higher than with the engine capacity-stronger cars? My incompetent logic tells me: The more engine capacity, the less speed, so the quieter you can run the car and the less fuel consumption. To be able to say what is most economical, one must know w o you drive the most. For people who drive a lot of AB at a speed of approx. 130 km/h upwards, a 150 hp car is probably cheaper than a 70 hp rotary organ, which must be constantly pressed out. For people who drive a lot of city is probably the low-performance small car first choice. But also I think you could drive a car with more engine capacity more economical than a weakling. A hybrid probably (if at all) only interesting for city drivers, but there comes m What do you say? Please tell me what the reality looks like!
