Basically think of the behaviour of a car when driving force is being applied to all four wheels instead of just the front or the back. It will bring the nose of the car back towards neutral, which is to say, if your car is oversteering, it will reduce that oversteer unless all four of your wheels have broken traction (which is another thing entirely), and if it is understeering already… well, you really shouldn’t be applying driving force to those front wheels!
There are certain cars that cleverly mitigate this or manipulate the power distribution, i.e. AWD is merely the means by which they can send power to some wheels and maybe even apply braking force to others, and this includes hybrid systems. That allows you to take extra liberties with certain cars, but of course the tradeoff is that it’s heavier (consider 918: 1650kg or so compared to the LaFerrari and P1 at about 1200kg). Or, even, the Focus RS, which is a very porky 1680kg and has that “drift mode” thing that people engage when they want to add about forty degrees of positive camber to their rear wheels by forcefully applying it to the kerb.
