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

245 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.

They need an engine capable or pulling 40 tons up a slope without breaking down and a high revving engine won’t cut it.
