Heheh...

For every wheel. That makes (for a 4WD) 200kW or 268HP. And max torque would be 2000Nm or 1500 lbf-ft

Diesels, eat your hearts out. 😀

Horsepower means little when dealing with such insane ammounts of torque.
 
Power equal force multiplied by speed. As speed increase, the force available decreases (at twice the speed at the same power, you have twice the force if the power figure is constant).
So you could have that insane amount of torque at 3 km/h, but at 100 km/h it won't have more torque than other engines developing 200kW.
This would be great for trucks, as their 8-speed or more gearboxes I assume are both expensive and heavy. Having such engine could totally remove their need for gearboxes

meh yea no gearbox...trade off i guess.

If you have 1500 lbf-ft at low rpm, you really don't need a gearbox. The gearbox is only used because all internal combustion engines have very low torque at low rpm (and even won't work at low rpm at all).
Have you seen the torque of an engine? It isn't even plotted at rpm lower than idle (cause it's not enough to pull the engine, not to move the car)

In-wheel motors? That's a LOT of unsprung weight right there.

That would be mostly a problem during breaking - accelerating it with such a huge torque is a joke. However, braking could be regenerative, or even electric with the energy sent to some resistive load to be lost there - just like on biiig diesel-electric trucks

might be useful at high speeds, though those speeds might be so high they are unecessary. gear box has loses too...trade off.
