Answer 1

Power = force x speed. The smaller engine makes less force but moves faster. This makes it ideal for lighter vehicles because it’s more fuel efficient. The larger engine spins slower with more force, making it ideal for heavy vehicles and towing. The higher force makes it easier to accelerate heavy loads up to speed.
