The Abarth 500 (or Abarth 595), like all front-wheel drive sports cars, can suffer from poor traction due to the high torque that is discharged onto the wheels.
This is especially evident when exiting a curve, where the inside wheel is partially relieved of the weight that is on it due to the load shift caused by centrifugal force: one of the two wheels is thus able to unload a much lower torque to the ground than the other. Remember that a free differential has the characteristic of always dividing the torque into two equal parts, so the maximum torque that can be unloaded to the ground is limited by the grip of the wheel with the least load.
