Final answer:
A forward CG on a car typically results in a slower cruise speed due to increased drag caused by increased downforce on the front tires.
Step-by-step explanation:
In physics, the position of the center of gravity (CG) plays an important role in determining the stability and performance of an object. When the CG is located towards the front of an object, it is said to have a forward CG. Now, in terms of a car's cruise speed, a forward CG generally results in a slower cruise speed.
This is due to the fact that a forward CG shifts the weight of the car towards the front, causing increased downforce on the front tires. This increased downforce improves traction and stability, but it also increases drag, which can limit the car's top speed.
On the other hand, a rearward CG shifts the weight towards the back of the car, reducing downforce on the front tires and decreasing drag. This can result in a faster cruise speed.
