Kinda-sorta.

An engine's power is determined by two factors, the turning force the engine can create and how fast it can spin for a given amount of turning force.

To get good acceleration you need a bit of both. Amazing turning power but only one turn/minute wouldn't work particularly well. Nor would an engine that'd spin like crazy but very weakly.

Generally, bigger engines are better at turning force and poorer on spin, while smaller engines are better at spin but poorer at turning force.

Now, obviously there are things you can do with gear boxes, to turn slow and strong into fast and a bit weaker, or fast and weak into slower and stronger.

But usually, for two engines with a similar power(horsepower or kW) rating, a bigger engine is better for acceleration.

Can a small car with a small engine accelerate as much a larger car with a lager engine?

A small car with a small engine can accelerate as much as a larger car with a larger engine, but it depends on various factors such as power-to-weight ratio, traction, and drivetrain efficiency. If the smaller car is significantly lighter or has a more efficient design, it can potentially match or exceed the acceleration of a larger car. Additionally, the type of transmission and driving conditions can also play a crucial role in determining acceleration performance. Ultimately, while size and engine displacement matter, they are not the sole determinants of acceleration capability.


Does the height of a car affect a car's speed?

The cross sectional area of a car is dependent on its height. As the area changes the drag on the car, it is likely that increasing the height of a car will also reduce its top speed. There are many other factors that affect a car's maximum speed so a change in height may not always result in a change in top speed.

How does gearing down affect the speed of a car?

Gearing down increases the engine's revolutions per minute (RPM) and torque, but decreases the speed of the car. This allows the engine to work at a more efficient RPM range for the desired speed or acceleration.


Why would a car shake during acceleration?

The pistons are running in the cylinders of the engine, so when the rpm of the engine rises, the pistons quickley build up speed. It is this rapid acceleration of the pistons that casue the car to shake.

Does the acceleration of a car affect its speed?

Yes, acceleration directly impacts the change in speed of a car. A higher acceleration will cause the car to increase its speed more rapidly, while a lower acceleration will result in a slower increase in speed.
