Editing Weight transfer (section)

==Traction==
Load transfer causes the available [[traction (engineering)|traction]] at all four wheels to vary as the car brakes, accelerates, or turns. This bias to one pair of tires doing more "work" than the other pair results in a net loss of total available traction.  The net loss can be attributed to the phenomenon known as [[tire load sensitivity]].

An exception is during positive acceleration when the engine power is driving two or fewer wheels.  In this situation where all the tires are not being utilized load transfer can be advantageous.  As such, the most powerful cars are almost never [[front wheel drive]], as the acceleration itself causes the front wheels' traction to decrease. This is why sports cars usually have either [[rear wheel drive]] or [[all wheel drive]] (and in the all wheel drive case, the power tends to be biased toward the rear wheels under normal conditions).
