Why do cars have more horsepower than tractors?

Tractor engines are desired to produce high torque at relatively low RPM’s. Cars need high HP for speed (at the expense of pulling power or torque). Tractor engines generally don’t care how big or heavy they are and they are built for heavy loads, whereas car engines try to be light and compact.

Why do tractors have less HP than cars?

This has to do with rev band to get vehicle speed. An industrial, marine or agricultural diesel engine is all about torque and the car engine all about speed. If you could imagine driving a car that reved to just 2000rpm and you want to drive on the autostrade at 130km/hr.

Why do tractors have so little horsepower?

Originally Answered: Why do tractors have so little horsepower? They have a lot of torque, to pull heavy weigh. They’re not designed to go fast, also when you pull weight, you don’t want to go fast. It’s easy to lose control of the load, and puts a lot of strain on the drivetrain.
