What is the difference between an engine built for speed, and an engine built for power

391 views

I’m thinking of a sports car vs. tow truck. An engine built for speed, and an engine built for power (torque). How do the engines react differently under extreme conditions? I.e being pushed to the max. What’s built different? Etc.

The simple answer is that there isn’t really a difference. All other things being equal, speed is directly a function of power. The engines are the same, the differences are in the gearing and the design of the vehicles.

The one area where differences may arise is that there will be a bit more focus on power-to-weight ratio over durability in engines for lighter, faster vehicles.
