eli5 why trucks don’t use small displacement high revving engines

246 views

Like, you see cars like ferrari making absurd power figures with small block engines, like a 4 liter making 800hp. Is it just a cost thing that they would rather use a 10 liter? It makes the same power, and thanks to the transmission it’ll get the same torque at the wheel.

I should clarify, when I say trucks I’m talking those tractor trailer style, 18 wheelers as we call them in the usa
