What does front and rear track mean?

[JasonFitz]

Front track refers to the distance between the center planes of the two front wheels, while rear track is the distance between the center planes of the two rear wheels. These two measurements can be either identical or different. The difference between front and rear track is intentionally designed - having a wider front track than rear track provides benefits when cornering at high speeds: the outer front wheel bears greater force, and a wider front track reduces the moment of roll during cornering, which is why front track is generally wider than rear track. Generally speaking, a wider track is more favorable for handling stability, as well as for body styling and cabin spaciousness, while also improving lateral stability. However, a wider track usually increases the overall width and weight of the vehicle, and may also lead to the problem of mud being thrown onto the side of the vehicle body.
