Commercial vehicles are not as powerful as you think... The Scania P-series which is often used for garbage trucks in Europe has engines ranging from 200hp to 500hp [0]. Cargo vans like the Fiat Ducato are typically not much more than 100hp.

Cars on the other hand... The Mercedes GLE mid-range SUV starts at 245hp, and has options all the way up to 612hp. Why on earth do you need so much power in a family car?
