Parisa, if a mid rear engined car doesn't have the excess speed before the corner then it doesn't steer as well into the corner as a front rear car. At a steady speed into the bend, or when accelerating, the front rear car has more grip on the front axle. But it also needs more friction to turn in so overall it is slightly slower than a mid rear engined car in the right circumstances.
The slowed down excess speed at the corner entry of the mid rear engined car causes the car to push outwards at the rear as a result of the braking energy in combination with the curve angle. You have more grip on the rear axle if you go on the gas again and the car drives the curve almost with very little steering movement because it rotates due to the mass forces through the curve and not mainly by the steering angle. So is has lower friction on the front wheels.
Just to add, this driving technique is far away from the classical drift because you do not counter steer which would reduce the speed any more but you can reduce the steering angle in this case.
