From what I have found, generally FWD vehicles have better traction because the weight of the engine and transmission are over the front wheels. This means better traction in snow and rain than RWD. But RWD has better performance when turning. So does it mean FWD will have a higher maximum slip...
The graph is relationship between longitudinal force and slip ratio under the conditions of 0 longitudinal acceleration and flat road(0 angle of inclination). Which line represent FWD or RWD? Does FWD or RWD have higher maximum slip ratio?
