200KG for the motor sounds very high?

That's definitely extremely high - brushless motors with much higher power (~80hp) are in the 50kg range (see for example EV218).

Interesting! UQM has the "PowerPhase® Select 50" which is a 30kW motor. I would say this counts as the "very lightweight motor technology" I speculated they were using because you can't get any datasheets or information or even a price for the UQM products.

40hp 200kg brushless motors are extremely common by comparison. Dozens of places will sell you one for a few grand.

If I'm reading correctly, the AC-35 has a peak rating of 47.78 horsepower, and weighs 43.9kg.

Presumably the 200kg motors you're looking at are not intended to be part of a moving vehicle. Those are likely intended for use in factories or shops where the weight is of little concern but durability is at a premium.
