To be fair, that test way way above legal speeds. I don't think it's representative even of motorway performance. I don't see your point however - what I'm saying is that at 130kmh (standard motorway speed in most of europe) a 70-90hp subcompact (by far the most common car in europe and the world in general) is running at above 80% max power (testified by the fact that as soon as there's a significant incline their speed will fall back to 110-120). So running long times under heavy engine load is quite normal for cars
