IGBT modules ...

Just don't forget that the car motor probably draws enormous start current
and you cannot let it have it. This means dynamic current limiting, which
is not so simple because you cannot use linear constant current regulation
at that dissipation and you cannot switch IGBTs that are so large quickly
(which is good in a way because of the 'broadcast factor').

You didn't happen to run across anything that might handle about 150-200A?

I just got asked if I could build a controller for a older electric car.
It uses a big honking (technical electrical car term ....) stainless steel
coil that operate as a cross between a rheostat and a heat sink. Very
inefficient to say the least.
