So a 9" series DC motor?!?
Warp 9"
Impulse 9"
Kostov 9"

Not too sure if anyone imported a Chinese equivalent.
So the short answer is NO but the long answer is YES.

These are bit small, looking for something bigger, like:
Motor type: DC or AC for 2000 kg car
Voltage(V): 72 -144V (max 230V)
Continuous current:
Peak Current: 250 Amps continuous
600 Amps for 30 Seconds
Continuous power:
Peak power: 25kW – 45kW
70kW – 100 kW
Speed(RPM): 4000RPM minimum
Maximum Temperature: 140C
Continuous Torque:
Maximum Torque: 140Nm min
300+Nm Max
Cooling: Liquid (Water)
Warranty: 1 year or more
Anything else? Recuperative breaking (use motor as generator when press brakes, for get back some power by charging battery)

21kW continuous, 75kW peak
144V
Description says drives a 2000kg vehicle very well.
No regen though
It's a 9" series DC motor...

An induction motor about the same size will typically have the same power.

300Nm peak at 100kW peak would be 3183RPM
So 140Nm at 3183RPM would be 46kW continuous.
2000kg is quite big.

Is this a 4WD or SUV?

TBH I don't know of any "cheap" permanent magnet motors that would fit this profile.
IF you had $10-15k to spend on the motor that would be ok. :o

Otherwise there are 11" series DC motors or equivalent induction motor that would do 100kW+.
But I don't think they are "cheap" either.
Leaning on the induction side I would probably look at 11kW 6-pole in a 160-frame industrial motors.
This should get you 100kW+ at 3,500RPM and weight about 110kg.
